Testosterone is a male hormone and has no influence in the development of breasts (mammary glands), estrogen the female hormone does,
It stimulates lactation in the mammary glands, and is produced by pituitary gland
Estrogen is the primary hormone that stimulates the development of the mammary gland. It promotes the growth of breast tissue and ducts, preparing the gland for potential milk production during pregnancy and lactation.
Being healthy is the only real stimulant of production of spermatozoa. (Sperm cells).
Andosterone and Testosterone are secreted by the adrenal gland.

Mammary gland
Mammary glands can be enlarged through hormonal changes, such as during puberty, pregnancy, or breastfeeding. Hormone therapy or certain medications may also be prescribed to stimulate growth in some cases. However, it's important to consult with a healthcare provider before attempting to increase mammary gland size due to potential risks and side effects.
The mammary papillae can also be referred to as the mammary gland or the teat. The adult female pig or aka sow, has anywhere from 4-9 pairs of teats. Each teat has streak canals which is where the milk is delivered to the end of the teat for drinking by her young, aka piglets.
Mammary glands are the source of milk production in female (and some male) mammals
Dihydrotestosterone (commonly abbreviated as DHT) is the hormone that promotes the development and growth of the prostate gland, as well the external genitalia (penis and scrotum) in men.
Cleavage itself is not necessary during development - it is a result of development, specifically of mammary gland development during puberty in humans. Mammary gland development is important because the mammary gland provides 100% of a newborn's nutrition up to 24 months after birth.
