Relative to dihydrotestosterone, the affinities of progesterone, norgestimate, 3-ketodesogestrel, gestodene, and levonorgestrel for the androgen receptor are 0.003, 0.005, 0.118, 0.154, and 0.220, respectively. 91,92 The relevance of this latter finding in humans is unknown. It is a prodrug B. This synthetic version of progesterone, unlike natural progesterone, has androgenic activity, which means it may have effects comparable to male hormones. These include levonorgestrel and norgestrel. The progestins of this class retain varying degrees of androgenic activity that possibly accumulate with that of the exogenous androgen. Norethisterone acetate. Desogestrel, norgestimate and drospirenone (3rd / 4th generation) have the least androgenic activity. The least 'androgenic' progestins often added to OCPs include norethindrone, norethindrone actetate, desogestrel, norgestimate and drosperisone.The most 'androgenic' progestins in OCPs have names like levonorgestrel and norgestrel. This means it has low progestational and estrogenic activity and also tends to be less androgenic than second generation progestins. Using Progestins in Clinical Practice. It has both strong progestational and strong antiovulatory activities C. It has additional androgenic acitivity D. It does not counteract the beneficial effect of estrogen on lipid profile. Desogestrel (DSG) is an oral third-generation progestogen with potent progestational activity and lower androgenicity. These potentially favorable properties led to the study of DSG in combination with TE. Desogestrel (3.4) Progestins with least Androgenic Activity. ... Hormonal … The clinical efficacy is as good as that of the old progestogens. In 1969 I discovered that it was the progestogens with inherent oestrogenic activity, norethisterone acetate and ethynodiol diacetate, PIP: The androgenic activity of progestins used in oral contraceptives (OCs) may be responsible for the adverse changes in lipid and lipoprotein metabolism, so researchers are continuing to work on developing progestins that reduce androgenicity. subdermal implants have the disadvantages of androgenic side effects and unpredictable bleeding patterns. Moreover, the androgenic activity of progestins within the testosterone derivatives also varies, and while some may have high or moderate androgenic activity, others have only low or no such activity. Pregnane Progestin (0) Norethynodrel (0) Ethynodiol Diacetate (0.6) Norethindrone (1.0): Lower limit reference. It is a prodrug B. Medroxy progesterone acetate. Receptor selectivity. I started Yaz, an anti-androgen birth control, 3 months ago in addition to adopting a healthier diet. These potentially favorable properties led to the study of DSG in combination with TE. ... particularly norgestimate, desogestrel, and gestodene. Androgenic activity. In this category, the low-androgen index of these pills makes them the ones with the least androgenic activity. no androgenic activity. i.e., extent of maximization of progestational … Progestational activity is the desired pharmacologic effect of progestins used in OCs, whereas androgenic activity, which increases the potential for adverse metabolic and physical side effects, is undesired. Desogestrel (DSG) is a highly effective progestin with low androgenic activity and high antigonadotrophic activity (De Bastos et al., 2014). Nestorone showed no androgenic or anabolic activity. A synthetic progestogen structurally related to levonorgestrel, with progesterone hormone receptor agonistic activity, used as a contraceptive and hormone replacement agent.

The effect of 19-nortestosterones on lipoproteins prompted the development of less androgenic compounds, but the obvious benefit of the new progestins (desogestrel, gestodene, norgestimate) is a reduction in the symptoms associated with the androgenicity of the older compounds. Gestodene has relatively high affinity for the glucocorticoid receptor, about 27% of that of the corticosteroid dexamethasone. The varying progestational “potencies” attributed to different COC preparations are based on pharmacological experimental models. Ortho Tri-Cyclen ( Norgestimate ): 0.15. Drospirenone [SEDA-32, 748; SEDA-33, 86] Electrolyte balance Drospirenone has antimineralocorticoid activity that is eight times greater than that of spironolactone, of which it is an analogue [37R ]. For example, desogestrel is a very potent and androgenic progestin but its usual oral contraceptive dose is 0.15 mg instead of 1.00 mg for norethindrone. desogestrel. Oral DSG in combination with various TE doses produced 100% azoospermia (Table I ). oincreased androgen potency related to estranes (norgestrel, levonorgestrel, norgestimate, norelgestromin, desogestrel) Dienogest - a 19-norprogestin gonane with increased progesterone receptor activity and decreased androgenic activity Desogestrel is a prodrug of etonogestrel (3-ketodesogestrel), and, via this active metabolite, it has progestogenic activity, antigonadotropic effects, very weak androgenic activity, very weak glucocorticoid activity, and no other hormonal activity.

A Comparative Study of Drospirenone and Desogestrel: An Overview of Benefits and Side Effects. Pregestational only … Desogestrel Desogestrel (DSG) is an oral third-generation progestogen with potent progestational activity and lower androgenicity. The potencies and activities of six progestational agents, norethindrone, levonorgestrel, desogestrel, medroxyprogesterone acetate (MPA), progesterone (P) and norgestimate have been evaluated using standard laboratory bioassays. Ortho Tri-Cyclen ( Norgestimate ): 0.15. Femilon For Ovarian Cyst: Androgen excess disorders in women range from hirsutism and seborrhea to polycystic ovaries, Insulin resistance, and Acne vulgaris (pimples). The endocrine activities measured are those most closely related to the clinically important actions of contraceptives. Progestogens without androgenic activity used in implants would be a significant advance. For example, levonorgestrel has a high androgenic index, which can cause adverse reactions in women who are sensitive to androgenic activity. It is a prodrug B. Desogestrel is a prodrug of etonogestrel (3-ketodesogestrel), and, via this active metabolite, it has progestogenic activity, antigonadotropic effects, very weak androgenic activity, very weak glucocorticoid activity, and no other hormonal activity.
