V. Progestins with least Androgenic Activity. Different combined oral contraceptives and the risk of ... Time-Dependent Effects of Oral Contraceptive Use on Breast ... Studies have found that combined birth control pills containing newer-generation progestins such as desogestrel, gestodene, norgestimate, drospirenone, and cyproterone acetate are associated with a 1.5- to 3-fold higher risk of VTE than birth control pills containing first-generation progestins such as levonorgestrel and norethisterone. 1,2 Consequently, new forms of COCs were developed containing 20 to 35 μg EE2 and new progestins that can provide effective contraception with less . These pills contain a synthetic estrogen, usually ethinylestradiol, and a synthetic progesterone or progestin, of which several are available, combined in the same pill.

It includes a combination of an estrogen (usually ethinylestradiol) and a progestogen (specifically a progestin).When taken correctly, it alters the menstrual cycle to eliminate ovulation and prevent . For this reason, a major design target was the antigonadotropic action ( Henzl and Edwards, 2000 ). The Gonane Family: This classification is further subdivided into two groups: Second-generation progestins have varying degrees of androgenic and estrogenic activities. 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. 4 All generations of progestin were associated with an increased risk of VTE, and third-generation users (GSD, DSG) had a slightly higher risk compared with second-generation users (LNG). However, the authors focused on the . Rather than referring to arbitrary 'generations' of progestins, a more scientific approach is to consider progestins in 'families,' grouped by structural similarities. Second-generation combined oral contraceptive pills contain lower doses of estradiol (20, 30, or 35 mg) and the progestin norethindrone and its derivatives, including levonorgestrel (4). Hemostatic effects of third- and second-generation oral contraceptives: absence of a causal mechanism for a difference in risk of venous thromboembolism. 117 Downloads; Abstract. Finally, the newest progestins, such as chlormadinone acetate (not available in the . COCs contain an estrogen component and one of a dozen different progestins ().Low-dose COCs (formulations containing <50 mcg ethinyl estradiol) are a safe and reliable contraceptive option for the vast majority . Pregnane Progestin (0) Norethynodrel (0) Ethynodiol Diacetate (0.6) Norethindrone (1.0): Lower limit reference. 2-6 Cohort analysis of trends in mortality due to ovarian cancer demonstrate that women who were born after 1920, ie, from generations who had used OCs, consistently show decreased rates of . Norethindrone is a synthetic progestational substance with some anabolic, estrogenic, and androgenic properties. The aim for use in oral contraception is for high progestational selectivity and low androgenic effects. Third-generation combined oral contraceptive pills con- INTRODUCTION — Combined estrogen-progestin oral contraceptives (COCs), also known as birth control pills, provide reliable contraception as well as several noncontraceptive benefits. Affecting the ovulation in a dose-dependent manner: This activity occurs by suppressing the midcycle peaks of LH and FSH. - Rebuilds endometrium. Progestins can also act to decrease levels of some hormones so can be used to treat hormonally sensitive cancers, for transgender hormone suppression and for precocious puberty. Globally, oral contraceptives are the third most widely used contraceptive method and used by over 100 million women [1, 2].As an effective method of birth control, oral contraceptive use could not only prevent unintended pregnancies but also generate numerous non-contraceptive health benefits, including alleviating premenstrual dysphoric disorder symptoms, ameliorating dysmenorrhea and . The main difference between them is the type of progesterone which is used. The Estrane Family (typically, first-generation progestins): consists of norethindrone and other progestins that metabolize to norethindrone.These include norethindrone acetate and ethynodiol diacetate. Abstinence 2. Download. - Increases cervical mucus fluidity and production. Other progestins such as drospirenone or cyproterone acetate combined with ethinyl-estradiol (EE . Since then it has gone through several incarnations. Since then, use of the pill has spread exponentially, overtaking other reversible methods of contraception and providing simple, safe and effective protection against pregnancy (United Nations Department of Economic and Social Affairs, 2007).According to recent estimates, the pill is used by 9% of . 1 Oral contraceptives (OCs) have been consistently linked to reduced risk of ovarian cancer. It works by stopping a woman's egg from fully developing each month. Changes the motility & secretion pattern within the fallopian tube. This leads to an alteration in protein synthesis and results in an inhibition of LH release. Among women who used pills containing desogestrel, gestodene or norgestimate (the new generation of prog- Previously described increased levels of coagulation factors were also greater with third-generation preparations, probably as a result from the greater reversal of the effects of the estrogen component of combined oral contraceptives by second-generation progestins not observed with the third-generation preparations (68). 1) Diethylstilbestrol (DES) 2) Bisphenol A. There are four generations of progestins in the market, with varying levels of androgenic activity; therefore, various kinds of OCP [12] [13][14][15] harbor diverse desired or adverse defects .

Both studies found that users of third-generation oral contraceptives had an increased risk of venous thromboembolism when compared with users of levonorgestrel-containing second-generation oral contraceptives (odds ratio [OR] 2.7; 95% confidence interval [CI] 1.6, 4.6; 17 and 1.5 [95% CI 1.1, 2.1], 18 respectively)(Table 2) Bloemenkamp et al .
