Sperm within the testicle itself are not capable of fertilizing an ovum on their own. They complete the maturation process in the epididymis.
No, sperm are small packets of genetic material designed to fertilize an oocyte in the female reproductive tract. In fact, the sperm have just enough resources to get to the oocyte - the oocyte must supply much of the energy and resources necessary to complete fertilization. However, if a female were to ingest sperm, the female's digestive tract would break the sperm down into component amino acids which would provide minimal nutrients to the female.
Fertilization occurs in the oviduct of the female reproductive tract
capacitation. Capacitation is a series of biochemical changes that sperm go through in the female reproductive tract. It involves removing certain coatings from the sperm head and increasing the sperm's ability to swim and penetrate the egg. Once capacitated, the sperm is able to fertilize the egg and initiate the process of conception.
It is called the vulva, which is literally the opening of the vaginal tract.
the nucleus is where DNA is stored and the flagellum is another major part commonly linked to the sperm cell.
The woman's whomb.
The fallopian tubes.
1-5 days
The penis is the organ than delivers semen to the female reproductive tract during sexual intercourse.
Sperm entering a woman's stomach cannot make her pregnant. The stomach is not connected to the reproductive tract.
Because the female reproductive tract is continuous with the peritoneal cavity through the fallopian tubes, it is possible for sperm to enter the peritoneal cavity.
Yes. Unless one of the testes or tubes leading from them is damaged, both testes will produced and deliver sperm to the reproductive tract.
Vas deferens, urethra, and penis. The vas deferens transports sperm from the epididymis to the ejaculatory duct, which empties into the urethra; the urethra carries sperm through the penis to the outside of the body and into the female reproductive tract. -masteringbiology.com
Yes, sperm can live up to 72 hours after ejaculation
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.
It is called the cloaca The male chicken does not have a penis and there is no penetration of the female reproductive tract at the time of mating. Instead the female inverts her cloaca which comes in contact with the male's inverted cloaca and receives the sperm. The cloaca is then drawn back into the hen's body and the sperm are captured. They then begin the journey up the length of the reproductive system. The sperm live inside the female reproductive system for up to 10 days and each time an ovulation occurs (every 24-26 hours in good egg producers) the egg can become fertile.
If the sperm do not find the egg they die off in about 5-7 days depending on how hostile the reproductive tract of the women and are absorbed by the womens body or disposed of just like a period or discharge.
