Estrogen and Testesterone
If the testes are not maintained at a temperature about 2 °C lower than body temperature the process of spermatogenesis will not take place, so that is why it is important for the testes to descend into the scrotum during maturation.
Testes is balls, pennis is pen
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The main endocrine glands include the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal glands. The hypothalamus is a neuroendocrine organ. Other organs which are not so well known for their endocrine activity include the stomach, which produces such hormones as ghrelin.
Sperm production requires an environment that is neither too hot or too cold. The cremaster muscles are those that will raise or lower the scrotal sac. If the testes are too warm, the cremaster muscles loosen and the scrotal sac will hand lower. If the testes are too cold, the cremaster muscles will control and draw them up closer to the body for warmth. So it's all about temperature control.
Steroids are a class of lipid molecules that have 4 carbon rings.
Testosterone

There are typically two testes situated in the scrotum. The scrotum is a sac of skin that houses and protects the testes, which are responsible for producing sperm and hormones.
gonodotropic hormones
Females do not have testes. Testes are male reproductive organs. The female equivalent of testes is ovaries, which produce eggs and female sex hormones.
Male hormones, such as testosterone, are primarily produced in the testes. The Leydig cells within the testes are responsible for producing and releasing testosterone into the bloodstream.

Cryptochidism- failure of testes to descend from the abdomen (develop there) to scrotum. 1. surgery or hormones to correct 2. sterility is not fixed 3. testes atrophy, potential site of cancer
The male testes secrete two different types of hormones. The first hormone that is secreted through the testes is the reproductive hormone. The second hormone that is secreted from the testes is the endocrine hormone secretions.
The brain, testes, ovaries and the pancreas even if its a little.
The testes gland secretes testicles.
