2. 6. Regulation and function of the human fallopian tube

   Author : Kjell Wånggren; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Fallopian tube; endometrium; embryo; transport; prostaglandin; receptors; progesterone; mifepristone; LIF; LIFR; gp130;

   Abstract : The Fallopian tube is essential for human reproduction. Transport of the spermatozoa, the egg, and later the pre-embryo is believed to be aided by muscular contractions in the wall of the Fallopian tube and cilia in the mucosa. READ MORE

4. 7. Factors of importance for the outcome of IVF-treatment in women with tubal infertility

   Author : György Csemiczky; Karolinska Institutet; Karolinska Institutet; []
   Keywords : In vitro fertilization; grade of tubal damage; extent of reconsructive surgery; E2; P4; prognostic factors; ovarian failure; endometrium; implantation.;

   Abstract : In vitro fertilization embryo transfer (IVF-ET) is a well-established infertility treatment caused by damage of the fallopian tube, which is one of the largest diagnostic categories in most IVF programs. This study evaluates factors of importance for the outcome of IVF-treatment: age, tubal damage grade, extent of reconstructive surgery, endocrine ovarian function and endometrial development.

5. 8. Culture and vitrification of human preembryos

   Author : Fredwell Hambiliki; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Despite improvements in stimulation protocols, culture media formulations and laboratory protocols, the success rates in human IVF remain disappointingly low. The ability to successfully cryopreserve supernumerary embryos in a given IVF cycle without losing significant embryo viability is essential to maximize the cumulative benefit of a given treatment cycle.

6. 9. Progesterone receptor modulators in contraception : clinical implications of ovarian and endometrial effects

   Author : Cecilia Berger; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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.

7. 10. Immune cell composition and cytokine expression in the pregnant and non-pregnant uterus

   Author : Ylva Crona Guterstam; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The success of implantation and further development of the embryo is heavily dependent on the endometrial immune cell composition and its ability to communicate with fetal semi-allogeneic trophoblast cells. Although our understanding of the immune cell population in the uterus has improved, its precise role in normal reproduction and reproductive disorders is still not fully resolved. READ MORE
