2. HUMAN REPRODUCTION

Human reproduction encompasses various processes including gametogenesis, insemination, fertilisation, and development during pregnancy. The male and female reproductive systems each play distinct roles, with spermatogenesis occurring in the male testis and oogenesis in the female ovaries. Following fertilisation, the zygote undergoes division and implantation leading to pregnancy, which culminates in parturition, the delivery of the baby.

    Human Reproduction

    Human reproduction involves the formation of gametes, fertilization, and subsequent embryonic development leading to childbirth.

    The Male Reproductive System

    The male reproductive system comprises the testes, accessory ducts, glands, and external genitalia, and is responsible for sperm production and hormonal regulation.

  • 2.2

    The Female Reproductive System

    The female reproductive system plays a crucial role in human reproduction, including the formation of ova, fertilization, and support during pregnancy.

    Gametogenesis

    Gametogenesis is the process of gamete formation, which includes sperm production in males and ovum production in females.

    Menstrual Cycle

    The menstrual cycle is the reproductive cycle in female primates marking the hormonal changes that regulate ovulation and menstruation.

  • 2.5

    Fertilisation And Implantation

    Fertilisation in humans involves the fusion of sperm and ovum, leading to the formation of a zygote, followed by implantation in the uterus.

    Pregnancy And Embryonic Development

    This section details the stages of pregnancy and the development of the embryo following fertilization.

  • 2.7

    Parturition And Lactation

    Parturition involves the delivery of the fetus, driven by neuroendocrine signals, while lactation refers to milk production for feeding the newborn.
