Pregnancy and parturition (childbirth) are physiological processes that involve the development and birth of offspring in mammals, including humans. 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 …

Oogenesis: Definition, Steps, Development, Regulation
Oogenesis is the process by which female germ cells, known as oogonia, develop into mature ova (eggs). It is a complex and highly regulated process that occurs within the ovaries, involving several stages of cell division and maturation. Understanding oogenesis is crucial for comprehending female fertility, reproductive health, and the …
Spermatogenesis: Definition, Steps, regulation
Spermatogenesis is the process by which male germ cells, called spermatogonia, undergo transformation into mature spermatozoa (sperm cells). It is a complex and tightly regulated process that occurs within the seminiferous tubules of the testes. Understanding spermatogenesis is crucial for comprehending male fertility, reproductive health, and the development of treatments …
Physiology of Fertilization: Definition, Steps, Regulation
Fertilization is a complex physiological process where spermatozoa (sperm) and oocyte (egg) fuse to form a zygote, initiating the development of a new organism. This process involves intricate interactions between male and female reproductive systems, culminating in the fusion of genetic material and the onset of embryonic development. Understanding the …
Physiology of Menstruation: A Detailed Overview
Menstruation, also known as the menstrual cycle or menses, is a complex physiological process that occurs in females of reproductive age. It involves the cyclical shedding of the endometrium (the lining of the uterus) and is regulated by intricate interactions between hormones from the hypothalamus, pituitary gland, ovaries, and uterus. …
