What happens to a sperm as it passes through the epididymis?

The epididymis (plural, epididymides) is a tightly coiled mass of thin tubes that carries sperm from the testes to the ductus deferens in the male reproductive system. Sperm matures as it passes through the epididymis so that it is ready to fertilize ova by the time it enters the ductus deferens.

Which of the following will occur immediately after ovulation?

After ovulation , if you are not pregnant, within 48 hours, the egg moves along the fallopian tubes, disintegrates and is absorbed back into the body. The corpus luteum survives and continues to produce progesterone for around 12 to 14 days.

Why does only one egg rather than for eggs develop during oogenesis?

The unequal cytoplasmic division that results in one egg and three polar bodies ensures that a fertilized egg has ample nutrients for its journey to the uterus.

Which layer of the uterus is the site for implantation?
