In this Video lecture, I have covered Male and Female Reproductive System of Human Reproduction Chapter( Class XII BIOLOGY ).
The male reproductive system consists of external organs. The testes in the scrotum produce the male gamete, sperm, which is ejaculated in seminal fluid by the penis.
The female reproductive system primarily consists of internal organs. The female gamete, ovum, is produced in the ovaries and is released monthly to travel to the uterus via the Fallopian tubes.
Fertilization can occur if the penis is inserted through the vulva into the vagina and sperm is ejaculated towards the cervix. If an ovum is currently in the uterus, it can then be fertilized by sperm that manage to enter the cervix.
Once fertilized, an ovum becomes a zygote and if all goes well, develops into a fetus in the uterus.
Natural birth occurs when the fetus is pushed from the vagina after nine months in the uterus.
