UNIT II - ANATOMY & PHYSIOLOGY OF THE REPRODUCTIVE SYSTEM

2.1 Female Organs of Reproduction

External genitalia (Vulva): Mons pubis, labia majora, labia minora, clitoris, vestibule (urethral and vaginal openings), Bartholin's glands, hymen.
Internal genitalia:
  • Vagina - muscular canal, 8-10 cm, acid pH (3.5-4.5), Doderlein's bacilli
  • Uterus - pear-shaped, 7.5 × 5 × 2.5 cm (non-pregnant); parts: fundus, body (corpus), isthmus, cervix
  • Fallopian tubes - 10 cm; parts: interstitial, isthmus, ampulla (fertilization site), infundibulum
  • Ovaries - almond-shaped, 3 × 2 × 1 cm; produce ova and hormones

2.2 Female Pelvis

Bones: 2 innominate bones (ilium + ischium + pubis), sacrum, coccyx
Joints: Sacroiliac (×2), sacrococcygeal, symphysis pubis (slight mobility in pregnancy due to relaxin)
Pelvic planes and diameters:
PlaneAP DiameterTransverseOblique
Inlet (brim)11 cm13 cm12 cm
Mid cavity12 cm12 cm12 cm
Outlet13 cm11 cm-
Pelvic types (Caldwell-Moloy classification):
  1. Gynecoid (round) - most favorable for vaginal delivery - 50%
  2. Android (male-type, heart-shaped) - poor prognosis
  3. Anthropoid (oval AP) - posterior position common
  4. Platypelloid (flat) - flat, wide - rare

2.3 Fetal Skull

Bones: 2 frontal, 2 parietal, 2 temporal, 1 occipital, 1 sphenoid (base)
Sutures: Sagittal (between parietals), coronal (frontal-parietal), lambdoid (parietal-occipital), frontal (between frontals)
Fontanelles:
  • Anterior (bregma): Diamond-shaped; junction of sagittal + coronal + frontal sutures; closes at 18 months
  • Posterior (lambda): Triangle; junction of sagittal + lambdoid; closes at 6-8 weeks
Key diameters of fetal skull:
DiameterMeasurementSignificance
Suboccipitobregmatic9.5 cmFully flexed head - most favorable
Suboccipitofrontal10 cmPartially deflexed
Occipitofrontal11.5 cmAverage head engagement
Mentovertical13.5 cmBrow presentation - largest
Submentobregmatic9.5 cmFace presentation
Moulding - temporary change in shape of fetal skull due to overlapping of cranial bones during passage through birth canal. Helps delivery but excessive moulding is pathological.
Fetopelvic relationship:
  • Lie - relationship of long axis of fetus to long axis of uterus (longitudinal, transverse, oblique)
  • Presentation - part of fetus in lower pole (cephalic, breech, shoulder)
  • Position - relationship of denominator to maternal pelvis
  • Attitude - relationship of fetal parts to each other (flexion = normal)
  • Engagement - widest diameter has passed through pelvic inlet

2.4 Menstrual Cycle

The menstrual cycle is ~28 days, regulated by the hypothalamic-pituitary-ovarian axis.
                    MENSTRUAL CYCLE OVERVIEW
       
  Phase:      Menstrual  | Follicular (Proliferative) | Ovulation | Luteal (Secretory)
  Days:        1-4/5     |         6-13               |   Day 14  |      15-28
  Hormone:     Low E+P   |      Rising Estrogen       |  LH surge |  Progesterone ↑
  Endometrium: Shedding  |      Proliferating         |  Mature   |  Secretory changes
Follicular phase (days 1-14):
  • FSH stimulates follicle growth → rising estrogen
  • Estrogen causes endometrial proliferation (glands elongate, spiral arteries grow)
  • Cervical mucus becomes watery, "ferning" pattern - sperm-friendly
  • LH surge triggers ovulation at day 14
Luteal phase (days 15-28):
  • Ruptured follicle → corpus luteum → produces progesterone
  • Progesterone: endometrium becomes secretory (glycogen-rich, coiled glands)
  • Cervical mucus thick, non-elastic - "no ferning"
  • Basal body temperature rises ~0.5°C
  • If no fertilization: corpus luteum degenerates → progesterone/estrogen fall → menstruation

2.5 Fertilization, Conception & Implantation

Fertilization - occurs in the ampulla of the fallopian tube, within 12-24 hours of ovulation. Sperm survive 2-5 days; ovum survives 12-24 hours.
Process:
  1. Capacitation of sperm in female genital tract
  2. Acrosome reaction - enzymes dissolve zona pellucida
  3. Only one sperm enters ovum (zona reaction prevents polyspermy)
  4. Formation of zygote (2n = 46 chromosomes)
  5. Cleavage - rapid mitotic division (blastomeres)
  6. Morula (16-cell solid ball) at day 3-4
  7. Blastocyst at day 4-5
Implantation - day 6-10 after fertilization; blastocyst embeds into posterior wall of uterus (decidua); HCG secreted maintains corpus luteum.

2.6 Placental Development & Functions

Placenta Development Diagram - showing decidua capsularis, decidua basalis, amnion, chorionic villi, umbilical vesicle at various stages from weeks 4-22
Fig: Development of the placenta and fetal membranes, weeks 4-22 (The Developing Human)
The placenta is a fetomaternal organ with two components:
  • Fetal part - derived from chorionic sac (villous chorion)
  • Maternal part - derived from endometrium (decidua basalis)
Decidua regions:
  • Decidua basalis - deep to conceptus; forms maternal placenta
  • Decidua capsularis - overlies conceptus
  • Decidua parietalis - remainder of uterine lining
Functions of the placenta (NREEH):
  1. Nutrition - glucose, amino acids, fatty acids to fetus
  2. Respiration - O2 from mother, CO2 from fetus
  3. Excretion - fetal waste products pass to maternal blood
  4. Endocrine - produces HCG, HPL, estrogen, progesterone
  5. Host defense - partial barrier (placental barrier); transmits maternal antibodies (IgG) → passive immunity
Placental barrier - 4 layers: syncytiotrophoblast, cytotrophoblast, connective tissue, fetal capillary endothelium (thins as pregnancy advances).
Weight/size at term: 500-600 g, 15-20 cm diameter, 2-3 cm thick; about 1/6 fetal weight.

2.7 Fetal Growth and Circulation

Key developmental milestones:
WeekDevelopment
4Heart begins beating; neural tube forms
8All major organs formed; embryo becomes fetus
12External genitalia differentiated; spontaneous movement
16Quickening (multiparae); lanugo appears
20Quickening (primiparae); vernix caseosa
24Viability (with NICU); surfactant production begins
28Eyelids open; 1 kg weight
36Lanugo disappearing; fat deposition
40Full term; 3-3.5 kg, 50 cm length
Fetal Circulation - Key Shunts (bypass routes):
  • Foramen ovale - right atrium → left atrium (bypasses lungs)
  • Ductus arteriosus - pulmonary artery → aorta (bypasses lungs)
  • Ductus venosus - umbilical vein → inferior vena cava (bypasses liver)
  • Umbilical vein - carries oxygenated blood from placenta to fetus
  • Umbilical arteries (×2) - carry deoxygenated blood from fetus to placenta
At birth: lungs expand → pulmonary resistance falls → foramen ovale, ductus arteriosus, ductus venosus all close.

UNIT III - ASSESSMENT & MANAGEMENT OF NORMAL PREGNANCY

3.1 Pre-conception Care

Goals: Optimize health before conception; identify and reduce risk factors.
Pre-conception counseling includes:
  • Folic acid (400 mcg/day) to prevent neural tube defects - start 3 months before conception
  • Rubella immunization
  • Management of chronic diseases (diabetes, hypertension, thyroid)
  • Genetic counseling (if family history of hereditary conditions)
  • Avoidance of teratogens (alcohol, smoking, certain drugs)
  • BMI optimization
  • Psychosocial readiness

3.2 Diagnosis of Pregnancy

Presumptive (subjective) signs:
  • Amenorrhea
  • Nausea and vomiting (morning sickness - 6th-12th week)
  • Breast changes (tingling, enlargement, darkening of areola)
  • Quickening (18-20 wks primi; 16-18 wks multi)
  • Frequency of micturition
  • Fatigue
Probable (objective) signs:
  • Uterine enlargement
  • Hegar's sign (softening of lower uterine segment - 6-10 wks)
  • Goodell's sign (softening of cervix)
  • Jacquemier's/Chadwick's sign (bluish discoloration of vagina)
  • Uterine souffle
  • Braxton Hicks contractions (painless, irregular - from 16 wks)
  • Positive pregnancy test (urine/serum HCG)
Positive (diagnostic) signs:
  • Fetal heart sounds (FHS - from 10-12 wks by Doppler; 20 wks by Pinard's stethoscope)
  • Fetal movements felt by examiner
  • Ultrasound visualization of fetus (gestational sac from 5-6 wks; fetal cardiac activity from 6 wks)

3.3 Physiological Changes in Pregnancy

Cardiovascular:
  • Blood volume ↑ 40-50% (plasma 50%, RBC 20-30%) → physiological anaemia
  • Cardiac output ↑ 30-50%
  • Blood pressure slightly ↓ in 2nd trimester, returns to normal at term
  • Physiological systolic murmur common
Respiratory:
  • Tidal volume ↑ 40%
  • Respiratory rate unchanged
  • Diaphragm raised by uterus → breathlessness in late pregnancy
Renal:
  • GFR ↑ 50% → glycosuria and proteinuria can be physiological
  • Urinary frequency 1st trimester (pressure of uterus) and 3rd trimester
  • Ureteral dilatation (right > left)
Gastrointestinal:
  • Nausea/vomiting (HCG)
  • Constipation (progesterone slows bowel)
  • Heartburn (gastric reflux due to relaxed lower esophageal sphincter)
  • Pica (abnormal food cravings)
Hematological:
  • Hb falls to 10.5-11 g/dL (physiological)
  • WBC increases
  • ESR rises
  • Clotting factors I, VII, VIII, IX, X increase → hypercoagulable state
Endocrine:
  • HCG: peaks at 10-12 wks; maintains corpus luteum; basis of pregnancy test
  • HPL (Human Placental Lactogen): anti-insulin; ensures fetal glucose supply
  • Progesterone: maintains uterine quiescence; raised from placenta from 10 wks
  • Estrogen: uterine growth, breast development, softening of ligaments
Musculoskeletal:
  • Relaxin softens pelvic ligaments
  • Centre of gravity shifts → exaggerated lumbar lordosis → backache
  • Diastasis recti (separation of rectus abdominis)

4.2 Stages of Labour

STAGES OF LABOUR
─────────────────────────────────────────────────────
1st Stage  │  Onset of labour → Full dilation (10 cm)
           │  Primi: ~12 hrs | Multi: ~7 hrs
           │  ├── Latent phase: 0-4 cm
           │  └── Active phase: 4-10 cm (≥1 cm/hr)
─────────────────────────────────────────────────────
2nd Stage  │  Full dilation → Delivery of baby
           │  Primi: ~50 min | Multi: ~20 min
─────────────────────────────────────────────────────
3rd Stage  │  Delivery of baby → Expulsion of placenta
           │  Normally ≤30 min (90% within 15 min)
─────────────────────────────────────────────────────
4th Stage  │  First 1-2 hours after delivery of placenta
           │  Critical observation period
─────────────────────────────────────────────────────

4.3 Mechanism of Labour (Cardinal Movements - for vertex presentation)

  1. Engagement - widest diameter passes through pelvic inlet
  2. Descent - continuous throughout labour
  3. Flexion - chin on chest; suboccipitobregmatic diameter (9.5 cm)
  4. Internal rotation - occiput rotates to anterior (OA position)
  5. Extension - head delivered by extension under symphysis pubis
  6. External rotation (restitution) - head rotates back to align with shoulders
  7. Expulsion - anterior then posterior shoulder delivered; rest of body follows

4.4 Monitoring Labour - Partograph

The partograph (also "labour care guide" per WHO 2020) is a graphical record of labour progress.
Components:
  • Fetal heart rate (every 30 min - 1st stage; every 5 min - 2nd stage)
  • Amniotic fluid (colour: clear/meconium/absent/blood)
  • Moulding (0/+/++/+++)
  • Cervical dilation - plotted against alert and action lines
  • Descent of head (in fifths above brim: 5/5 → 0/5)
  • Uterine contractions (frequency, duration per 10 min)
  • Oxytocin, drugs
  • Maternal vitals (BP, pulse, temp, urine)
Alert line - starts at 4 cm, moves at 1 cm/hr Action line - 4 hours to the right of alert line

4.5 First Stage Care

  • IV access, monitor vitals, auscultate FHS every 30 min
  • Per vaginal examination for cervical dilation, station, effacement
  • Partograph monitoring
  • Encourage ambulation and upright positions
  • Non-pharmacological pain relief: breathing techniques, back massage, warm water, TENS, hydrotherapy
  • Emotional support; birth companion (doula/family)
  • Oral hydration; light diet in early labour
  • Bladder care - void every 2 hours

4.6 Second Stage Care

  • Push with contractions; coach breathing
  • Birth position of woman's choice (upright, lateral, squatting, hands-and-knees)
  • Perineal support; warm compresses
  • Watchful waiting - no fundal pressure
  • Crowning → gentle head delivery, check for nuchal cord
  • Encourage spontaneous pushing (non-directed)
  • Birth of baby → note time
Immediate newborn care (after birth):
  • Dry and stimulate
  • Skin-to-skin contact (within 30-60 min)
  • Assess breathing; if not breathing → newborn resuscitation
  • Delayed cord clamping (1-3 min or until pulsation stops)
  • Initiate breastfeeding within 1 hour

4.7 Third Stage Management

Active Management of Third Stage of Labour (AMTSL) - Recommended:
  1. Oxytocin 10 IU IM within 1 min of baby's birth
  2. Controlled cord traction (Brandt-Andrews method) after signs of separation
  3. Uterine massage after placenta delivery
Signs of placental separation:
  • Uterus becomes globular and firmer
  • Gush of blood
  • Cord lengthens
  • Uterus rises in abdomen
Examination of placenta:
  • Maternal surface: 15-20 cotyledons, dull grey/red
  • Fetal surface: shiny, vessels visible
  • Membranes: complete
  • Umbilical cord: 3 vessels (2 arteries + 1 vein); length 50-60 cm
Stages of Labour - showing second stage spontaneous vaginal delivery sequence
Fig: Spontaneous vaginal delivery - second stage; crowning, head delivery, shoulder delivery (The Developing Human)

4.8 Fourth Stage

  • Close observation for 1-2 hrs post-delivery
  • Monitor: BP, pulse, uterine fundal height, lochia, perineal site
  • Uterus should be firm, contracted, at or below umbilicus
  • If uterus soft/boggy → uterine massage → oxytocin
  • Initiate breastfeeding; mother-baby bonding
  • Documentation - birth record
Drugs used in labour (GoI guidelines):
DrugUseDose
Oxytocin3rd stage, augmentation10 IU IM; 2-5 IU slow IV
Misoprostol3rd stage (if no oxytocin)600 mcg SL or oral
Magnesium sulphateEclampsia preventionPritchard regime: 4 g IV + 5 g IM each buttock
LignocainePerineal infiltration1% solution

UNIT V - NORMAL PUERPERIUM / POSTNATAL CARE

5.1 Definition and Duration

Puerperium - the period from delivery of the placenta until the return of the reproductive organs to their pre-pregnant state. Duration: 6 weeks (42 days) after delivery.

5.2 Physiological Changes (Involution)

Uterus:
  • Immediately post-delivery: 1 kg, at umbilicus
  • Descends ~1 cm/day
  • Day 7-10: midway between symphysis and umbilicus
  • Day 14: no longer palpable abdominally
  • 6 weeks: back to pre-pregnant size (~60 g)
  • Process: myometrial contraction, autolysis
Lochia (uterine discharge):
TypeDaysColourComposition
Lochia rubra1-4 daysBright redBlood, decidua, mucus
Lochia serosa5-14 daysPink/brownishSerous exudate, WBCs
Lochia albaDay 14 onwardsPale yellow/whiteLeucocytes, decidua, mucus
Offensive/purulent lochia = endometritis; heavy bleeding = subinvolution
Cervix: Soft immediately; internal os closed by 3 days; external os remains open (fish-mouth appearance in multiparae)
Vagina: Oedematous initially; regains tone by 6 weeks (but remains slightly lax)
Perineum: Oedema, bruising initially; heals by 2 weeks
Breasts:
  • Colostrum - days 1-3; thick, yellow; rich in antibodies (sIgA), proteins, fat-soluble vitamins
  • Transitional milk - day 4-10
  • Mature milk - day 10 onwards
Blood changes:
  • WBC leukocytosis (up to 20,000/µL) in first 24 hrs - physiological
  • Urine output increases (diuresis) in first few days
  • Hematocrit rises initially then normalizes
Temperature: Slight rise (milk fever) Day 2-3 as milk comes in - but >38°C on any day other than first 24 hrs = infection.

5.3 Postnatal Care

Immediate postnatal (first 24 hrs):
  • Monitor vitals, fundus, lochia every 30 min for first 2 hrs
  • Ensure bladder is emptied (urine retention common)
  • Initiate breastfeeding
  • Perineal hygiene
Ongoing postnatal care:
  • Encourage ambulation (reduce DVT risk)
  • Perineum: sitz bath, analgesics, hygiene
  • Breast care: correct latch, feed on demand, prevent engorgement
  • Bowel care: stool softeners if needed; first bowel movement by day 3
  • Contraception counseling before discharge
Minor disorders of puerperium:
  • After-pains (uterine cramps) - more common in multiparae and breastfeeding
  • Perineal discomfort - managed with ice packs, sitz bath, analgesics
  • Breast engorgement - frequent feeding, warm compresses
  • Hemorrhoids - sitz bath, laxatives

5.4 Lactation

Physiology of lactation:
  • Prolactin (anterior pituitary) - stimulates milk production (surge with each feeding)
  • Oxytocin (posterior pituitary) - milk ejection reflex (let-down); also promotes uterine involution
WHO recommendation: Exclusive breastfeeding for 6 months; continued for 2 years with complementary feeds.
Benefits of breastfeeding:
  • Passive immunity (sIgA)
  • Ideal nutrition, easily digestible
  • Bonding and emotional security
  • Reduces maternal breast cancer risk
  • Natural child spacing (LAM)
  • Economical, convenient, always right temperature
Lactational Amenorrhea Method (LAM): 98% effective if: baby <6 months + exclusive breastfeeding + amenorrhea.
Post-natal depression:
  • Baby blues (days 3-5): mild, tearfulness, anxiety - self-limiting
  • Postnatal depression (weeks 2-8): persistent low mood, anxiety - requires treatment
  • Postpartum psychosis (rare, 1 in 1000): confusion, hallucinations - emergency

5.5 Postpartum Family Planning

  • Progestogen-only pill: safe from day 21; suitable for breastfeeding
  • IUCD: can be inserted within 10 min of placenta (PPIUCD) or 6 wks post-delivery
  • Condoms: from first intercourse
  • Sterilization: can be done at cesarean or 6 wks postpartum

UNIT VI - ASSESSMENT & CARE OF THE NORMAL NEONATE

6.1 Newborn Assessment - APGAR Score

Assessment at 1 minute (resuscitation decisions) and 5 minutes (prognosis).
Sign012
AppearanceBlue/paleBlue extremitiesCompletely pink
PulseAbsent<100 bpm≥100 bpm
Grimace (reflex irritability)NoneGrimaceCry/cough/sneeze
Activity (muscle tone)LimpSome flexionActive flexion
RespirationAbsentSlow/irregularStrong cry
Score interpretation:
  • 7-10: Normal
  • 4-6: Moderate asphyxia → stimulate, oxygen
  • 0-3: Severe asphyxia → immediate resuscitation

6.2 Normal Neonate - Characteristics

Measurements at term:
  • Weight: 2.5-4 kg (average 3-3.5 kg)
  • Length: 48-52 cm
  • Head circumference: 33-37 cm (average 34-35 cm)
  • Chest circumference: 30-33 cm (HC > CC at birth)
Normal physiological adaptations at birth:
  • Lungs expand with first breath → surfactant reduces alveolar surface tension
  • Fetal shunts close (foramen ovale, ductus arteriosus)
  • Temperature regulation begins (non-shivering thermogenesis - brown fat)
  • Gut colonization begins
  • Jaundice (physiological) peaks at day 3-4; resolves by day 10 in term babies

6.3 Essential Newborn Care (ENBC)

W-A-R-M-T-H principle:
  • Warmth - dry immediately, skin-to-skin contact, KMC
  • Airway - clear if necessary (suction only if required)
  • Resuscitation - if not breathing by 30 seconds
  • Mother's milk - early initiation within 1 hour
  • Treatment/prevention of infection
  • Hepatitis B vaccine + Vit K1 (1 mg IM)
Routine care of newborn:
  • Cord care: keep dry; no application of powder/dung
  • Eye care: 1% tetracycline or 1% silver nitrate drops (ophthalmia neonatorum prophylaxis)
  • Vitamin K1 (phytomenadione) 1 mg IM - prevents hemorrhagic disease of newborn
  • Temperature: maintain at 36.5-37.5°C; prevent hypothermia
  • Feeding: exclusive breastfeeding; no prelacteal feeds
  • Kangaroo Mother Care (KMC) for low birth weight babies

6.4 Newborn Resuscitation

NEWBORN RESUSCITATION STEPS (NRP Algorithm)
─────────────────────────────────────────────────
Initial steps (30 seconds):
  → Warm, dry, stimulate, clear airway (position)
  → Assess: breathing? heart rate?
  
If HR <100 or gasping/apnea:
  → Positive Pressure Ventilation (PPV) with room air
  → 40-60 breaths/minute
  
At 30 seconds - re-assess:
  If HR <60 despite PPV:
  → Chest compressions (3:1 ratio with PPV)
  → 100% O2
  
If HR remains <60:
  → Epinephrine (0.1-0.3 mL/kg of 1:10,000 IV)
─────────────────────────────────────────────────

6.5 Congenital Anomaly Screening

  • First trimester: Nuchal translucency (NT) scan, combined test (NT + PAPP-A + Free β-HCG)
  • Second trimester: Triple/quadruple screen (AFP, HCG, estriol, inhibin A); anomaly scan at 18-20 wks
  • Screen for: Down's syndrome, neural tube defects, cardiac anomalies, cleft palate, club foot

UNIT VII - FAMILY WELFARE SERVICES

7.1 Methods of Contraception

Temporary Methods

A. Hormonal Methods:
MethodCompositionMechanismEffectiveness
Combined OCP (e.g., Mala-N, Mala-D)Estrogen + progestinInhibits ovulation; thickens cervical mucus; atrophies endometrium99.7%
Progestin-only pill (Mini pill)Progestin onlyThickens cervical mucus; thin endometrium99% (if taken correctly)
DMPA (Depo-Provera)Injectable progestinInhibits ovulation99.7%
Implant (Implanon)Etonogestrel rodInhibits ovulation>99%
Combined injectableEstrogen + progestinInhibits ovulation99%
Emergency contraception (EC):
  • Levonorgestrel 1.5 mg (or 2 × 0.75 mg) - within 72 hours (ideally 12 hours)
  • Ulipristal acetate - up to 120 hours
  • Cu-IUCD - most effective EC; up to 5 days
  • Mechanism: delays/inhibits ovulation; NOT abortifacient
B. Non-hormonal Methods:
MethodDescriptionEffectiveness
Condom (male)Latex barrier; also prevents STIs98%
Female condomPolyurethane; inserted before intercourse95%
Diaphragm + spermicideDome-shaped cap over cervix88-92%
Spermicides (Nonoxynol-9)Foam/gel/cream; disrupts sperm70-80% alone
IUD - Cu-T 380A (Copper-T)Copper device; inhibits sperm motility; prevents implantation99.4%
PPIUCDCopper-T inserted within 10 min of placenta99.4%
IUD - LNG-IUS (Mirena)Levonorgestrel-releasing; reduces menstrual blood loss>99%
Barrier principle - condoms must be stored away from heat/sunlight; check expiry; use from beginning to end of intercourse.
C. Natural/Traditional Methods:
MethodBasisNotes
Calendar/rhythm methodAvoid fertile days 10-17Unreliable for irregular cycles
Basal body temperature (BBT)Temperature rises after ovulationRetrospective only
Cervical mucus method (Billings)Spinnbarkeit (stretchy) mucus near ovulationRequires training
Lactational Amenorrhea (LAM)Breastfeeding suppresses ovulationEffective only <6 months, exclusive BF, amenorrhea
Withdrawal (coitus interruptus)Withdrawal before ejaculationVery unreliable (85% typical use)

Permanent Methods

Female Sterilization (Tubectomy / TL):
  • Mini-laparotomy (Pomeroy's method, Fimbriectomy) - most common in India
  • Laparoscopic sterilization (Filshie clip, Fallope ring) - preferred now
  • PPTL (postpartum tubectomy) - within 48 hrs of delivery
  • Reversal possible in <30% cases
  • Failure rate: 0.5/100 woman-years
Male Sterilization (Vasectomy / NSV):
  • No-Scalpel Vasectomy (NSV) - preferred technique; low complications; under local anaesthesia
  • Vas deferens occluded bilaterally
  • Does NOT affect sexual function or hormone levels
  • Not immediately effective - use contraception for 3 months/20 ejaculations (until azoospermia confirmed)
  • Failure rate: 0.1-0.15/100 woman-years
Medical Eligibility Criteria (MEC) - WHO Classification:
  • Category 1: No restriction (can use)
  • Category 2: Benefits outweigh risks (generally use)
  • Category 3: Risks outweigh benefits (generally do not use)
  • Category 4: Unacceptable health risk (do not use)

7.2 Balanced Counseling Strategy (BCS)

A job-aid tool developed for family planning counseling:
  1. Rule out pregnancy
  2. Ask about desire for future children
  3. Discuss all available methods
  4. Confirm choice
  5. Provide/refer for chosen method
  6. Follow-up and side-effect management

7.3 Role of Nurse/Midwife in Family Planning

  • IEC (Information, Education, Communication)
  • Eligible couple registration and follow-up
  • Distribution of oral pills and condoms
  • Insertion of IUCD (trained staff)
  • Referral for permanent methods
  • Follow-up for acceptors
  • Management of minor side effects
  • Motivating community through ASHA, ANM network
  • Maintaining eligible couple registers

7.4 Gender-Based Violence (GBV) in SRH

Types:
  • Physical abuse
  • Sexual abuse/rape
  • Psychological/emotional abuse
  • Economic abuse
Laws in India:
  • Protection of Women from Domestic Violence Act 2005
  • Sexual Harassment at Workplace Act 2013
  • IPC 376 (rape), IPC 304B (dowry death)
  • POCSO Act 2012 (child sexual abuse)
Role of nurse/midwife:
  • Universal screening for GBV in ANC/PNC visits
  • Non-judgmental listening, maintain confidentiality
  • Document injuries objectively
  • Refer to social worker, counselor, legal aid
  • Know local support resources/helplines

7.5 Youth-Friendly Services / SRHR

  • RKSK (Rashtriya Kishor Swasthya Karyakram) - adolescent health program
  • ARSH (Adolescent Reproductive and Sexual Health) clinics
  • Services: menstrual health, STI counseling, contraception info, nutrition, mental health
  • Nurses must provide non-judgmental, confidential care to adolescents
  • Reporting of MTP: mandatory under 18 yrs even with consent, must involve guardian
