Furthermore, all three progestins exhibited weak GR-mediated antagonistic activity. It is a prodrug B. Desogestrel (DSG) is a less-androgenic progestogen than levonorgestrel (LNG). 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. V. Progestins with least Androgenic Activity. Last Answer : C. It has additional androgenic acitivity. These potentially favorable properties led to the study of DSG in combination with TE. The third generation progestins are preferred as these progestins have the lowest androgenic activity." These results demonstrate the synergistic action of this steroid … They have developed norgestimate (NGM) which is a progestin with improved selectivity. Desogestrel is a new, potent progestogen with very low androgenic properties. Progestational activity is usually tested using the McPhail Index in immature rabbits, and also the pregnancy maintenance and the ovulation inhibition tests in rats.2 https://www.verywellhealth.com/different-progestin-types-906936 In 2011 it is COCs containing 150ug desogestrel and 3mg drospirenone which significantly increased endothelium-dependent vasodilation in both large vessels and peripheral microvasculature.3 .

Oral Contraceptive Androgenic Activity (low to high) Andogen activity based on Methytestosterone mg/28 days. Androgenic activity. 35 The androgen activity of the older oral contraceptives also inhibits the estrogen-related increase in sex hormone binding globulin (SHBG), and low SHBG has been associated with an … 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. Femilon controls hyperandrogenic states very efficiently by Ethinyl estradiol’s ability to raise SHBG as well as desogestrel’s inherent anti-androgenic activity. 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. Desogestrel (3.4) Progestins with least Androgenic Activity.

The androgenic potency of progestins in COC varies, as shown in Table 34.5. Desogestrel and norgestimate are newer progestins with a lower androgenic index. Q34.8 Dienogest and drospirenone are progestins with antiandrogenic properties. Medroxy progesterone acetate. Some have antiandrogenic activity but not as much as cyproterone acetate has.

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 (DSG) is a highly effective progestin with low androgenic activity and high antigonadotrophic activity (De Bastos et al., 2014).

Correlation with nuclear magnetic resonance signals. The androgenic properties of progestins determine their biological activity in the breast epithelium and reveal an unexpected role for AR activity in breast epithelial cell proliferation. These include levonorgestrel and norgestrel. The reported decrease of SHBG levels and displacement of T from its binding sites caused by these progestins may further contribute to increased free T levels ( Pugeat et al, 1981 ; Darney, 1995 ).

Although approved by the US Food and Drug Administration (FDA) in 1959 as a treatment for endometrial and renal cancers, it is now primarily used for contraception because of its ability to inhibit follicular maturation and ovulation. A selective progestin has progestational effects at relatively low concentrations or doses and androgenic effects at only relatively high concentrations or doses. In this category, the low-androgen index of these pills makes them the ones with the least androgenic activity. desogestrel.
