"menthol cigarette" AND fertility

Short answer: The "mint" (menthol) flavoring itself isn't what causes infertility — it's the tobacco smoke in the cigarette. Menthol cigarettes carry the same fertility risks as regular cigarettes, and possibly more indirectly, because menthol makes smoking feel smoother/easier to inhale, which can lead people to smoke more or find it harder to quit.

What actually damages fertility

Cigarette smoke (menthol or non-menthol) contains nicotine, cyanide, carbon monoxide, and other toxicants that harm reproduction through several well-documented mechanisms:

In males (Campbell-Walsh Urology; Goldman-Cecil Medicine):

Reduced sperm count and density (smokers show roughly 13-17% lower sperm density than non-smokers)
Decreased sperm motility and abnormal sperm morphology
Increased seminal oxidative stress and sperm DNA fragmentation/damage
These effects are dose-dependent - more cigarettes per day, worse outcomes

In females (Berek & Novak's Gynecology; Harrison's Principles of Internal Medicine):

Accelerated loss of ovarian egg reserve - since eggs can't regenerate, this can bring on menopause 1-4 years earlier than in non-smokers
Damage to fallopian tube function, raising rates of both infertility and ectopic pregnancy
Reduced likelihood of embryo implantation and lower success rates with IVF/fertility treatment
Shorter, more irregular menstrual cycles

A psychiatry reference table (Kaplan & Sadock's Comprehensive Textbook of Psychiatry) lists smoking as raising the relative risk of infertility by about 60%, in both sexes combined. General reproductive health sources put infertility rates in smokers (male or female) at roughly double that of non-smokers.

Does the "mint" part matter specifically?

No strong evidence singles out menthol as adding a unique fertility-toxic effect beyond what any cigarette smoke does. The peer-reviewed literature on menthol cigarettes (systematic reviews, toxicology studies) focuses mainly on:

Menthol increasing smoking's appeal/addiction potential, especially in youth, because it cools and numbs the throat, making harsh smoke feel milder
This can lead to deeper inhalation, more cigarettes smoked, and greater difficulty quitting - which indirectly increases cumulative toxic exposure and therefore fertility risk

I did not find any study directly attributing infertility to menthol/mint flavoring as a distinct chemical cause, separate from tobacco smoke exposure itself.

Bottom line

"Mint cigarettes" cause infertility risk through the same mechanism as any cigarette - toxic combustion products damaging sperm and eggs, tubal/ovarian function, and implantation. The mint flavor isn't a separate fertility toxin, but it can make the habit easier to sustain, which means more smoke exposure over time. Quitting smoking (any type) is the single most effective step to protect fertility in both partners - sperm quality can improve within about 3 months of quitting, since that is the length of one full spermatogenesis cycle.
