Why is the female reproductive system more complex than the male reproductive system ?
Female reproductive system is more complex as compared to that of males. The complexity of sexual structures in females is due to the fact that it produces sex cells, accepts sperms from male and supports their movement up to egg, fertilization , implantation, embryo development and supports subsequent post fertilization changes. Production of hormones, having complex reproductive organs (Ovary, Oviducts, Uterus and Vagina) and mammary glands are also the other features of the female reproductive system.
