Begin at the ovaries of susie and the testes of billy.track the processes of ovulation for susie and ejaculation of billy.
Shkiper50 [21]

Ovulation and ejaculation are the processes that involve the release of the female and male gamete  for the process of fertilization.

<u>Ovulation</u>

  • The release of an egg from one of a woman's ovaries is known as ovulation.
  • Ovulation usually lasts for one day and takes place two weeks before a woman anticipates getting her period, in the midst of her menstrual cycle.
  • However, the procedure takes a different amount of time for every woman, and it might even change from month to month.
  • A sperm cell can fertilize an egg when it exits a woman's ovary and enters the fallopian tube.
  • Sperm can survive for three to five days inside a woman's reproductive system.
  • The uterine walls thicken during ovulation in order to accommodate a fertilized egg. On the other hand, if the egg is not fertilized, the uterine lining is lost around two weeks later, which results in menstruation.

<u>Ejaculation</u>

  • Ejaculation, the male reproductive system's discharge of sperm cells and seminal plasma.
  • Sperm are transported from the testicles and the epididymis, where they are stored, to the beginning of the urethra, a hollow tube that runs through the pen!s and transports either sperm or urine.
  • In the second stage, known as the actual ejaculation, the semen is transported through the urethra and expelled from the body.
