Norgestrel is a progestogen, or an agonist of the progesterone receptor. [6] The biological activity of norgestrel lies in the levo enantiomer, levonorgestrel, whereas the dextro isomer is inactive. [6] As such, norgestrel is identical in its hormonal activity to levonorgestrel except that it is half as potent by weight. [6]
Norgestimate is a rapidly and completely converted prodrug, mainly of norelgestromin (17β-deacetylnorgestimate or levonorgestrel 3-oxime), but also of levonorgestrel (3-keto-17β-deacetylnorgestimate) to a lesser extent (22 ± 6% of an administered dose or about 40–70 μg) [2] and of levonorgestrel acetate (levonorgestrel 17β-acetate) in ...
[44] [45] Recognizing that some patients cannot receive combined oral contraceptives due to a contraindication to the estrogen component, these findings show promise that progestogens can be an alternative therapy capable of producing adequate symptom relief. Progestogen-only pills are typically not given to patients experiencing severe symptoms.
Possible weight gain: Some women may experience slight weight gain when using the implant. [24] However, current studies are not conclusive because they do not compare the weight of women using implants with a control group of women not using the implant. The average increase in body weight in studies was less than 5 pounds (2.25 kg) over 2 years.
Research shows that older men and women with low testosterone have lower red blood cell counts and an increased risk of developing anemia. Anemia can produce symptoms like fatigue, weakness, loss ...
NETE is a prodrug of norethisterone in the body. [13] Upon reaching circulation, it is rapidly converted into norethisterone by esterases.Hence, as a prodrug of norethisterone, NETE has essentially the same effects as norethisterone, acting as a potent progestogen with additional weak androgenic and estrogenic activity (the latter via its metabolite ethinylestradiol). [14]

An online survey conducted by the Cleveland Clinic of 1,174 men 18 years or older, found that 72% of men would rather do household tasks, such as cleaning the bathroom or mowing the lawn, than see ...
