Life style and infertility
Fertility of an individual may be influenced by life style choice . Tobacco smoking and alcohol intake contribute
to infertility. Cigarette smoking interferes with folliculogenesis (nicotine and other harmful chemicals in cigarettes
interfere with estrogen synthesis), embryo transport, endometrial receptivity, endometrial angiogenesis, uterine
blood flow and the uterine myometrium . Some damage is irreversible, but stopping smoking can prevent
further damage . Smokers are 60% more likely to be infertile than non-smokers. Smoking reduces the chances of
IVF producing a live birth by 34% and increases the risk of an IVF pregnancy miscarrying by 30% . Canabis
smoking, such as marijuana causes disturbances in the endocannabinoid system, potentially causing infertility .
Alcohol intake, on the other hand, is associated with elevated oestrogen level and this elevated oestrogen level
reduces FSH secretions which then suppresses folliculogenesis and results in anovulation
