Explain the primary concept of the male and female reproductive systems.

(N/A) Reproduction is a biological process that ensures the continuity of a species by passing genetic material from one generation to the next. In this process,the genetic material of a single cell is doubled and transmitted.
Humans are sexually reproducing and viviparous organisms. The reproductive events in humans include the formation of gametes (gametogenesis). The transfer of sperm into the female genital tract is known as insemination. The fusion of male and female gametes is called fertilization,which leads to the formation of a zygote.
Following fertilization,the zygote undergoes cleavage to form a blastocyst,which attaches to the uterine wall (implantation). This is followed by embryonic development (gestation) and the delivery of the baby (parturition).
These reproductive events occur after puberty. There is a significant difference between reproductive events in males and females; for example,sperm formation continues even in old men,whereas the formation of ova (oogenesis) ceases in women around the age of $50$ years.
