gonads are endocrine glands that produce gametes like sperm and egg. And they're also going to be responsible for secrete ing sex hormones. They're gonna be regulated by lutin izing hormone and follicle stimulating hormone from the pituitary. Now, the test is there gonna be male gonads and these air gonna produce steroid hormones called androgens, which are male sex hormones. The most famous and the main one is testosterone. This is going to regulate the development and maintenance of male sexual characteristics. For example, the deepening of the voice now malaria, inhibitory substances also gonna be secreted by the test ease. And this is going to prevent female reproductive anatomy development.
