Prolactin
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.
Prolactin is not considered a tropic hormone because it does not act on another endocrine gland to regulate the secretion of another hormone. Instead, prolactin primarily functions to stimulate milk production in mammary glands after childbirth.

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.
Thickness in the pituitary gland could be caused by a prolactinoma. It is a benign tumour of the pituitary gland that produces a hormone called prolactin.

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.
The hormone involved in milk production is prolactin, which is produced by the anterior pituitary gland. Oxytocin is the hormone responsible for the ejection or release of milk from the mammary glands in response to suckling or stimulation of the nipples.
The hormone primarily responsible for the growth of mammary gland ducts during pregnancy is estrogen.
There are four in all:Estrogen is the hormone that helps control breast cell proliferation and division. Breast development during puberty begins after the ovaries start to secrete estrogen.Progesterone is a steroid hormone that works together with estrogen to regulate breast development.Prolactin causes the alveoli to take nutrients (proteins, sugars) from the blood supply and turn them into breast milk.Oxytocin causes the cells around the alveoli to contract and eject milk down the milk ducts. This passing of the milk down the ducts is called the “let-down” (milk ejection) reflex.
Prolactin is not considered a tropic hormone because it does not act on another endocrine gland to regulate the secretion of another hormone. Instead, prolactin primarily functions to stimulate milk production in mammary glands after childbirth.
The hormone that causes ovulation to occur is called luteinizing hormone (LH). LH is produced by the pituitary gland in the brain.
