How long it takes for sperm to reach the egg

Fertility basics Achieving a healthy pregnancy is a complicated, multi-stage process involving two people.

How Long Can Sperm Survive After Ejaculation?

Watch as the ovulation process occurs, and then millions of sperm swim upstream on a quest to fertilize an egg. Once the vaginal, cervical, and uterine barriers have been overcome, the sperm have to go through the narrowest part of the journey: There is still a chance that fertilization will occur, but there is likely an underlying fertility issue that may be causing you difficulty getting pregnant. Estrogen from the developing ovarian follicle then inhibits further pituitary production of FSH. A long, whiplike tail propels each sperm toward the waiting egg. By releasing GnRH, the hypothalamus is simply permissive in allowing the pituitary to stimulate the ovary in the female and the testicle in the male. This fertile period of time may be associated with an increase in one's basal body temperature the day after ovulation," he says.

How long does it take for sperm to reach to reach the egg – what can affect this flow?

The same phenomenon occurs in women. In women who require hormone treatment to stimulate ovulation, so many follicles may grow so large that when ovulation occurs it causes strong cramps, and a woman may even become sick enough to require several days of rest in the hospital. Even if a man has perfectly healthy sperm and enough of them, it can still be a struggle for fertilization to actually happen. Sperm can survive for a few days in the female reproductive system — hence a sperm ejaculated during intercourse on a Monday could fertilise an egg ovulated on the Tuesday or Wednesday! Yet this is where the fertilized egg must implant itself and grow during the next nine months into a full-size baby.

There is no particular amount of time that it takes, it just depends on a number of factors. Can sperm meet egg before ovulation? In the first half of the cycle, before ovulation, estrogen stimulates the buildup of a thick, hard layer of tissue called the endometrium to line the uterus, but this lining does not become receptive to the fertilized egg until after ovulation, when the secretion of progesterone causes it to soften. Most sperm die within minutes after ejaculation inside the vagina or outside the woman's genital tract. Sperm then continue to invade the cervical mucus at that point much like a single-file line of army ants.
