Sexual reproduction is a method of reproduction in which the male sex cell fuses with the female reproductive cell. This process results in the formation of a zygote, which gradually develops into an adult that is similar to the parents. Sexual reproduction is one of the two types of reproduction, the other being asexual reproduction. In sexual reproduction, the offspring produced are genetically different from both parents, which increases genetic diversity. Sexual reproduction is the mode of reproduction in animals and humans. The reproductive organs in females include ovaries, fallopian tubes, uterus, cervix, and vagina, while the reproductive organs in males include testes, vas deferens, urethra, and penis.
