While the benefits of progestin use in hormone replacement therapy (HRT) are well recognised as far as endometrial protection is concerned, their risks and drawbacks have generated controversial articles. The data related to the progestin effect on breast tissue has been interpreted differently from country to country. However it has been admitted that,

Role of progestins in contraception
Acta Obstetricia et Gynecologica Scandinavica, 2005Progestins have been used for contraception for more than 30 years. The main goal was to develop a contraceptive method devoid of the metabolic or clinical side‐effects associated with the use of estrogens. The development of new contraceptive methods and formulations is time‐consuming and requires devotion, belief, and also strong economical basis. As

Progestin implants for contraception are highly effective, safe, and the most convenient choice for many women. Progestin implants currently on the market, preparing for launch, or under investigation are reviewed here. Their basic galenic and pharmacokinetic features, as well as their contraceptive effectiveness, are described.

Nomenclature of the gonane progestins
Contraception, 1999The use of gonane nomenclature can be traced back to the early 1960s when the first compound submitted for trial the carbon-18 homologue of the anabolic agent Nilevar was named bisnortestosterone. However the confusion about how this compound was named led scientists to introduce the gonane system for naming bisnortestosterones and structurally ...
