Gamete Production And Fertilisation

Sperm are the male gametes which are produced from germline stem cells by meiosis Testes produce sperm cells in the seminiferous tubules and testosterone in the intersticial cells The prostate gland and seminal vesicles secrete fluids that maintain the mobility and viability of the sperm

The ovaries contain immature ova in various stages of development. Each ovum is surrounded by a follicle that protects the developing ovum and secretes hormones Mature ova are released into the oviduct where they may be fertilised by sperm to form a zygote
