   Nyckelord :Mifepristone; levonorgestrel; endometrial receptivity; emergency contraception; blastocyst implantation; integrins; cyclooxygenase;

   Sammanfattning : Ovulation and endometrial development as well as contraceptive efficacy was studied after treatment with the antiprogestin mifepristone. Mechanism of action after treatment with the gestagen levonorgestrel or mifepristone in doses effective for emergency contraception was also evaluated. LÄS MER

Many underlying causes of human infertility have been overcome by assisted reproductive techniques; nevertheless, the implantation process remains one of the rate-limiting step as regards the success of the treatment.

   Sammanfattning : Background: The dialog between the developing embryo and receptive endometrium is under the control of ovarian steroids and numerous biomolecules, some of which have been suggested as markers of endometrial receptivity. Unintended pregnancies are common. The standard treatment with levonorgestrel (LNG, 1. LÄS MER

7. 5. Progesterone receptor modulators in contraception : clinical implications of ovarian and endometrial effects

   Författare :Cecilia Berger; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Emergency contraception (EC) offers a last chance to prevent an unwanted pregnancy after unprotected sexual intercourse (UPSI) but before pregnancy occurs, for example after contraceptive failure, non-use of contraception or after rape. Progesterone receptor modulators (PRMs) exert their effect through acting as partial antagonists and partial agonists of the progesterone receptor (PR) and have proven effective for EC in low doses by postponing or inhibiting ovulation if it was taken preovulatory in the menstrual cycle.
