Equine estrogens, or horse estrogens, are estrogens found in horses. [1] [2] [3] They include the following: [1] [2] [3] Estradiol; Estrone; Equilin (Δ 7-estrone) Equilenin (Δ 6,8-estrone) 17α-Dihydroequilin (Δ 7-17α-estradiol) 17β-Dihydroequilin (Δ 7-17β-estradiol) 17α-Dihydroequilenin (Δ 6,8-17α-estradiol) 17β-Dihydroequilenin (Δ ...
Conjugated estrogens (CEs), or conjugated equine estrogens (CEEs), sold under the brand name Premarin among others, is an estrogen medication which is used in menopausal hormone therapy and for various other indications.
8,9-Dehydroestradiol, or Δ 8-17β-estradiol, also known as estra-1,3,5(10),8-tetraen-17β-ol-3-one, is a naturally occurring steroidal estrogen found in horses which is closely related to equilin, equilenin, and estradiol, and, as the 3-sulfate ester sodium salt, is a minor constituent of conjugated estrogens (Premarin).

Alternatives exist for many animal-derived ingredients, and healthcare providers are increasingly incorporating awareness around animal-free drugs in their medical practice. [ 9 ] [ 4 ] A 2013 study in the BMC Medical Ethics contacted branches of six of the world's largest religions.
In 2002, the Women's Health Initiative study (WHI) that was designed to demonstrate additional benefits of conventional hormone therapy (study participants were given Prempro or a placebo) was terminated prematurely after preliminary data indicated small increases in the risks of breast cancer, heart attack and stroke in older women using ...
Estradiol is an estrogen, or an agonist of the estrogen receptors, whereas norethisterone acetate is a progestin (synthetic progestogen), or an agonist of the progesterone receptors. [14] Relugolix suppresses ovarian sex hormone production , whereas estradiol and norethisterone acetate provide hormonal add-back to reduce hypogonadal and ...
Estradiol is an estrogen, or an agonist of the nuclear estrogen receptors (ERs), the estrogen receptor alpha (ERα) and the estrogen receptor beta (ERβ). [1] [2] [6] In one study, the EC 50 Tooltip half-maximal effective concentration value of estradiol for the human ERα was 50 pM (0.05 nM) and for the human ERβ was 200 pM (0.2 nM).
