Question

how csn we say tat the repriductive system of a female is compleax than a male one??

Answer 1

The female reproductive system is complex than a male one because the male needs only to produce and deliver the gametes. But female need to produce nutrition and safe harbor for fatal development and then give birth and nourish the infant. And female reproductive physiology is cyclic and female harmones are secreted by a complex sequence compared to the relatively steady simultaneous secretion of regulatory harmones in the male.

Answer 2

it is due to the fact that it produces sex cell,accepts sperms from male,and support their movement to the egg,fertilisation,implantation,embryo development and post fertilisation changes 
on that basis we can say that reproductive system of female is complexed than male
