Examples
The increase in progesterone from the corpus luteum transforms the endometrium into a secretory structure, making it receptive to the newly fertilized ovum. 
The main difference between the male and female production of gametes is that oogenesis only leads to the production of one final ovum from each primary oocyte; in contrast, in males four sperm result from each primary spermatocyte.
