Endometrial biopsy study in people using hormonal birth control
Part of Women’s health & pregnancy clinical trials.
This early-phase study looks at doing an endometrial biopsy (a small tissue sample from the uterus) in people using a progestin-type contraceptive. It’s meant to test whether this approach works safely and how the uterus responds under these specific conditions.
Summary written for real people, not researchers, by Clin2.

This study looks at how well HIV treatment (ART) and a hormonal birth control method (DMPA shot or implant) work together, using small blood samples. It may help ensure safer, more effective HIV care and contraception for young women.
This study tests a new birth control pill to see how well it prevents pregnancy and if it's safe. It combines a lower dose of estrogen with a different type of progestogen that blocks male hormones.
This trial tests a new contraceptive patch to see if it can prevent ovulation (the release of an egg). If you are a healthy woman looking for a non-hormonal birth control option, this study may be a good fit.
This trial studies whether placing an etonogestrel hormonal implant can work as emergency contraception and prevent pregnancy. You may be a good candidate if you have regular periods and are not currently pregnant or trying to get pregnant.
This trial tests a new way to place a contraceptive implant (a small rod that prevents pregnancy) into the shoulder blade area instead of the arm. It might be a good option if you want long-term birth control and are healthy.
This study looks at how genes affect the way the body processes birth control pills. You take a low-dose pill for one cycle and have blood draws to measure hormone levels.
