Pills containing one of the newer types of progestogen hormone - such as drospirenone, desogestrel, gestodene, and cyproterone - are associated with an increased risk of VTE than pills containing older progestogens such as levonorgestrel and norethisterone, it was found.
In addition, noting the changes in the World Health Organization's medical eligibility criteria, and possible increased risk of HIV acquisition with injectable progestogens, there is a shift in emphasis away from injectable progestogens towards alternative long-acting reversible contraceptives (Cu IUDs, intrauterine systems, subdermal implants); and, because of the possible increased risk of HIV acquisition, emphasis is given to the importance of condom use for women who choose to use injectable progestogens.
Among specific topics are why the choice of progestin matters in neuroprotection, neuroactive steroids and peripheral neuropathy, somatostatin and neuroprotection in the retina, thyroid hormone action on glioma cells, and the obligatory functions of gonadotropins and progestogens during early embryogenesis and their role in adults.
Injectable contraceptives, ideal for women who struggle to remember to take the pill regularly, contain only synthetic progestogens administered every two to three months.
The OCs with desogestrel or gestodene and 20 meg of ethinyl estradiol implied relative risks of VTE that were 23% and 17% lower, respectively, than the risks for the same progestogens with 30 meg of ethinyl estradiol.
The OCs with desogestrel or gestodene and 20 mcg of ethinyl estradiol implied relative risks of VTE that were 23% and 17% lower, respectively, than the risks for the same progestogens with 30 mcg of ethinyl estradiol.
So Lidegaard and colleagues carried out a large-scale study to assess the risk of VTE for women using oral contraceptives with different progestogens.

It may, however, be dependent on whether it is given as a continuous combination versus a sequential regimen, how long it is given, at what dose and how it is administered, as well as which progestogens are used.
Progestogens are included in combination hormonal therapies with estrogen to prevent endometrial buildup, which can lead to cancer.
Synthetic progestogens (drugs with progesterone-like actions) are the "non-natural" progesterone often in HRT.
After reviewing the scientific literature on the biology of oestrogens and progestogens, the scientists concluded that HRT should be given a chance.
