progestogencontaining

Progestogen-containing refers to substances that contain progestogens, which are a group of steroid hormones. These hormones are crucial for the menstrual cycle, pregnancy, and embryogenesis in females. Naturally occurring progestogen is progesterone, but synthetic progestogens are also widely used. Progestogen-containing medications and devices are common in modern medicine. They are frequently employed in hormonal contraception, such as combined oral contraceptive pills (which contain both estrogen and a progestogen), progestogen-only pills (the "mini-pill"), injections, implants, and intrauterine systems (IUS). These contraceptives work by preventing ovulation, thickening cervical mucus to impede sperm, and thinning the uterine lining. Beyond contraception, progestogen-containing treatments are used in hormone replacement therapy to manage menopausal symptoms, particularly in women who still have a uterus, to protect the endometrium from estrogen's effects. They are also used to treat menstrual irregularities, endometriosis, and certain types of cancer. The specific type and dosage of progestogen used will depend on the intended medical application.
