Sperm dies after how long

The sudden release of LH is what triggers ovulation see fig. Within eleven to eighteen hours the male and female pronuclei sitting on opposite sides of the egg appear extremely prominent and get ready to converge. Pregnancy would not be likely if all the sperm got into the fallopian tubes at one time, because they would soon pass on into the abdominal cavity, and not be available to fertilize the egg except during a very brief, lucky interval. The decrease in progesterone and estrogen levels during menstruation then stimulates a renewed increase in FSH. The time required for the egg to develop the proper follicle necessary for ovulation is about fourteen days.

Occasionally women actually feel several hours of discomfort in their lower abdomen during ovulation; this discomfort is called Mittelschmerz.
