It is not known how long the damaging effects of smoking last after quitting butOne important investigation showed that cessation of smoking for at least two months before attempting IVF significantly improved chances for conception.
1.The phasing out and banning of smoking in home should be an integral part of human infertility treatment.
2.Further studies to show the correlation between the duration of exposure to cigarette smoke and the fertilization rate, are needed.
3.Further studies on the levels of reactive oxygen species (ROS) in the follicular fluid in passive smokers are needed.
