Human Reproduction

This chapter introduces the complete reproductive biology of humans — from the anatomy of male and female reproductive systems to the cellular processes of gametogenesis (spermatogenesis and oogenesis), the menstrual cycle and its hormonal control, fertilisation, implantation, embryonic development, parturition (childbirth) and lactation. You'll trace the journey of a sperm from the seminiferous tubule to the fallopian tube, the egg from the primary oocyte to the secondary oocyte, the development from zygote → cleavage → morula → blastocyst → embryo → fetus, and the complex hormonal interplay involving FSH, LH, testosterone, oestrogen, progesterone, hCG, hPL, oxytocin, prolactin, and relaxin. For NEET, this is one of the highest-yield chapters in the syllabus, contributing 5–8 questions every year on gametogenesis stages, menstrual cycle phases and hormones, fertilisation events, blastocyst structure, and parturition mechanism.
