21. Structural studies of proteins essential for fertilization
Sammanfattning : Where do babies come from? Even though it sounds like a fairly obvious question, it took more than 200 years to discover that sperm, whose first observation dates back to the 17th century, can penetrate into the oocyte and fuse with it. Interestingly, this initial study was carried out in starfish, and since then, scientists have addressed the fascinating question of how gamete recognition functions using very different model systems.

22. Women's experience of pain and pain relief in assisted reproductive technology
Sammanfattning : The overall aim of this thesis was to evaluate and compare different methods for pain relief during oocyte retrieval and to study women’s expectations and experiences of pain during oocyte retrieval in conjunction with in vitro fertilization. Paper I, an open prospective randomized controlled trial, including 160 women had the primary aims of comparing the pain relieving effects of electro-acupuncture and conventional analgesia, comprising opiates, in conjunction with oocyte retrieval, and to compare post-operative well-being between groups.

23. Factors of importance for the outcome of IVF-treatment in women with tubal infertility
Sammanfattning : 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. LÄS MER
24. Prenatal diagnosis in routine antenatal care : a randomised controlled trial
Sammanfattning : Nuchal translucency (NT) measurement combined with maternal age has been shown to identify women at an increased risk of carrying a fetus with Down's syndrome (DS) more accurately than does maternal age alone. The aim of this study was to evaluate more widely the effects of two different strategies for prenatal diagnosis. LÄS MER
25. Culture and vitrification of human preembryos
Sammanfattning : 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.
