Answer 2

Sperm production or spermatogenesis

• Within the brain, the hypothalamus and anterior pituitary control sperm production.
• The hypothalamus secretes gonadotropin-releasing hormone (GnRH), which acts on the anterior pituitary gland, stimulating it to release follicle stimulating hormone (FSH) and leutinizing hormone (LH).
• FSH and LH are released into the bloodstream and act only on the testes to encourage spermatogenesis within seminiferous tubules (action of FSH) and testosterone production by neighboring Leydig cells (action of LH) between the seminiferous tubules

• Millions of sperms are produced.
• Only one healthy sperm penetrates the ovum .
• Sperm tip has enzymes like hyaluronidase which helps to penetrate the ovum.
• Sperm fuses with the ovum to produce a zygote.
• The zygote undergoes rapid cell division to form emryo and further to foetus.
• The foetus is within a membrane sac attached to the uterus .
