258 views

Only a few dozen sperm out of millions make it to the fallopian tube after ejaculation. The fallopian tubes are the site where sperm and egg meet for fertilization. The journey is rigorous, and only the strongest sperm survive the trip through the cervix, uterus, and into the fallopian tubes. This natural selection ensures only the healthiest sperm have the chance to fertilize an egg.

FAQs & Answers

  1. Why do only a few sperm reach the fallopian tube? Only a few sperm reach the fallopian tube because the journey through the cervix and uterus is challenging, allowing only the strongest and healthiest sperm to survive.
  2. How many sperm are typically released during ejaculation? Millions of sperm are typically released during ejaculation, but only a few dozen make it to the fallopian tube.
  3. Where does fertilization occur in the female reproductive system? Fertilization usually occurs in the fallopian tube, where the sperm meet and merge with the egg.
