These processes are complex and involve intricate interactions between maternal physiology, fetal development, hormonal regulation, and structural adaptations. Pregnancy Pregnancy begins with fertilization of an egg by sperm, leading to the formation of a zygote. The … Read more

It is initiated by the fertilization of an egg by sperm, leading to the formation of a zygote, which undergoes successive stages of development. Key Stages of Pregnancy 1.Fertilization Fertilization typically occurs in the … Read more
Gonads are reproductive organs that play a central role in the development of sexual characteristics and the production of reproductive cells (gametes). In males, the gonads are the testes, and in females, they are the ovaries. Hormones Produced by Gonads • Male Gonads (Testes): 1.Testosterone: The primary male sex hormone responsible for developing male reproductive … Read more
