human reproduction class 12 biology handwritten notes

Here, these notes of human reproduction are efficient and very useful for NEET as well as class 12 boards. Human reproduction involves the process of creating offspring through sexual reproduction. In males, the primary reproductive organs are the testes, which produce sperm, while in females, the ovaries produce eggs. Fertilization occurs when a sperm cell from the male unites with an egg cell from the female, forming a zygote. The zygote then undergoes development in the female’s uterus, leading to pregnancy. Key stages include gametogenesis, fertilization, embryonic development, and childbirth. The menstrual cycle regulates female reproductive functions, while hormones like testosterone and estrogen control reproductive processes in both sexes. Reproduction ensures the continuation of the species.
