I think you mean 'viable' . . .
If the spermatazoa are lucky enough to get into the uterus (baby bed), they are viable only for a couple of days.
Sperm is indeed considered a foreign structure when in the female reproductive system. However, it is not considered an antigen because it does not come into contact with the blood, therefore the antibody process does not happen.
Sperms meet eggs through the process of fertilization. Sperms swim through the female reproductive tract towards the egg, which is released from the ovary during ovulation. When a sperm successfully penetrates and fertilizes the egg, it forms a zygote which eventually develops into an embryo.
after intercourse,millions of the sperms get deposited in the vagina...with the peristaltic movement of the sperms and the cilia present they move through the cervix..only thousands of sperms will be alive and reaches the uterus and only one sperm penetrates the ovum
Sperms are ejaculated into the female reproductive tract during sexual intercourse. They travel through the cervix, uterus, and fallopian tubes to reach the egg. When a sperm successfully penetrates the egg's outer layer, fertilization occurs, leading to the formation of a zygote.
Male sperm can survive in the female reproductive tract for up to 5 days, while female sperm can survive for up to 3 days.
Male sperm typically survive in the female reproductive tract for up to 5 days, while female sperm can survive for up to 7 days.
Lady's finger (OKRA), helps producing sperms... believe it. RESEARCHER myself.
stomach and female reproductive tract
The upper female genital tract consists of the body of the uterus, the fallopian or uterine tubes, and the ovaries.
The lower female reproductive tract consists of the vagina, cervix, and uterus. It is where sperm travel to reach the egg for fertilization, and where a fertilized egg implants and grows during pregnancy.
Sperms need to swim to reach the egg for fertilization. The journey from the male reproductive tract to the female reproductive system is lengthy, and active motility is essential for navigating this distance. Additionally, swimming allows sperm to overcome various barriers, such as cervical mucus, and helps them reach the egg during the short window of ovulation. Overall, swimming is vital for successful reproduction.
The penis is the organ than delivers semen to the female reproductive tract during sexual intercourse.
