*  Lynestrenol - Wikipedia
Lynestrenol itself does not bind to the progesterone receptor and is inactive as a progestogen.[7][8] It is a prodrug, and upon oral administration, is rapidly and almost completely converted into norethisterone, a potent progestogen, in the liver during first-pass metabolism.[7][8] No other metabolites besides norethisterone are formed from lynestrenol.[8] As such, its pharmacological activity is essentially identical to that of norethisterone.[9] The conversion of lynestrenol into norethisterone is catalyzed by CYP2C9 (28.0%), CYP2C19 (49.8%), and CYP3A4 (20.4%), while other cytochrome P450 enzymes are each responsible for no more than 1.0% of the total conversion.[8] It appears that lynestrenol first undergoes hydroxylation of the C3 position, forming etynodiol as an intermediate,[12] followed by oxygenation of the hydroxyl group to form norethisterone.[11] The peak blood levels are reached within 2 to 4 hours after oral administration, 97% of the administered dose being bound to plasma ...

*  Etonogestrel birth control implant - Wikipedia
Irregular bleeding and spotting: Many women will experience some type of irregular, unpredictable, prolonged, frequent, or infrequent bleeding when using Nexplanon or Implanon.[18] Some women also experience amenorrhea. For some women, prolonged bleeding will decline after the first three months of use. However, other women may experience this bleeding pattern through all three years of use. While these patterns are not dangerous, they are the most common reason that women give for discontinuing the use of the implant. After removal, bleeding patterns return to previous patterns in most women.[13][14][15][16]. Insertion complications: Some minor side effects such as bruising, skin irritation, or pain around the insertion site are common.[13] However, there are some rare complications that can occur, such as infection or expulsion.[13][19] In some cases, a serious complication occurs when the provider fails to insert, and the rod is left in the inserter. An Australian study reported 84 ...

*  Ethylestrenol - Wikipedia
Ethylestrenol, also known as ethyloestrenol or ethylnandrol and sold under the brand names Maxibolin and Orabolin among others, is an androgen and anabolic steroid (AAS) medication which has been used in the past for a variety of indications such as to promote weight gain and to treat anemia and osteoporosis but has been discontinued for use in humans.[1] It is still available for veterinary use in Australia and New Zealand however.[2] It is taken by mouth.[1] Side effects of ethylestrenol include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire.[1] It can also cause liver damage.[1] The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).[1][3] It has strong anabolic effects relative to its androgenic effects.[1] The drug also has strong progestogenic effects.[1] Ethylestrenol is a prodrug of ...
