Question

1. how sperm are formed and delivered by the male reproductive anatomy into the female reproductive anatomy

2. where ova come from and how and where the gametes meet.

Answer 1

1. Testes are important part of male reproductive system. Together with other accessory glands, testes are responsible for production of sperms and its movement towards female reproductive tract. The phenomena of spermatogenesis are predisposed by gonadotropic hormone produced by anterior pituitary. Testosterone and follicle stimulating hormone are required to produce sperms. Tunica albuginea comprise of very fine coiled tubes known as seminiferous tubules. These tubes lined with a layer of germ cells that mature into spermatozoa. The sperm cells are matured in epididymis. These sperm cells move into the vas deferens and ejected urethra through urethral orifice. Once sperm approach vagina, they move through cervical canal into the uterine cavity and move towards fallopian tubes. Nearly 500 sperm reach the tubes. If one of the sperm fertilizes an egg, It begins to multiply.

2. Ovaries produce ova/oocytes. Oocytes are transported towards fallopian tube. This is the place where the fertilization takes place by sperms. The fertilized egg moves towards uterus. The thick uterus lining promotes attachment of oocyte.
