In men, EE can additionally cause breast development, feminization in general, hypogonadism, and sexual dysfunction. Rare but serious side effects include blood clots, liver damage, and cancer of the uterus. [7] EE is an estrogen, or an agonist of the estrogen receptors, the biological target of estrogens like estradiol. [7]

Other potential causes of male breast enlargement such as mastitis, [27] [56] lipoma, sebaceous cyst, dermoid cyst ...

Progesterone is a progestogen, or an agonist of the nuclear progesterone receptors (PRs), the PR-A, PR-B, and PR-C. [1] In one study, progesterone showed EC 50 Tooltip half-maximal effective concentration values of 7.7 nM for the human PR-A and 8.0 nM for the human PR-B. [5] In addition to the PRs, progesterone is an agonist of the membrane progesterone receptors (mPRs), including the mPRα ...
[151] [153] In addition to breast cancer risk, estrogen alone and estrogen plus progestogen therapy are associated with higher breast cancer mortality. [154] With 20 years of use, breast cancer incidence is about 1.5-fold higher with estrogen alone and about 2.5-fold higher with estrogen plus progestogen therapy relative to non-use. [151]
