FERTILITY FACTS1 . A man is, in theory, fertile all the time . 2. A woman matures one egg per cycle, which is fertilizable for no more than 12 hours after release. 3. About six days before ovulation, the cervix opens and produces a mucous secretion which keeps sperm alive for 3-6 days, enabling them to survive inside the woman until the egg is released . 4 . A woman is fertile due to this mucous for about 6 days before ovulation and only 2 days after, allowing for the release and life of the egg. 5. The rest of the time she is infertile because the cervix is sealed with a sticky mucous plug which blocks the passage of sperm.Ferility Education Trust, Cardiff, U.K . 1997. --> return to menu / back ...
