RESEARCH QUESTION: Elective single-embryo transfer (eSET) at blastocyst stage is widely used to reduce the frequency of multiple pregnancies after IVF. There are, however, concerns about increased risks for the offspring with prolonged embryo culture. Is it possible to select embryos for transfer at the early cleavage stage and still achieve low twin rates at preserved high live birth rates? DESIGN: A prediction model (PM) was developed to optimize eSET based on variables known 2 days after oocyte retrieval (fresh day 2 embryo transfers; double-embryo transfers 1999-2002 (n=2846) and SET 1999-2003 (n=945); n total=3791)...

We present the first systematic review and meta-analysis of sexual function in women with polycystic ovary syndrome (PCOS) compared with women without PCOS. Data on this topic are limited and often contradicting. Sexual function is influenced by endocrine, mental and social factors, which are often compromised in women with PCOS. The main outcome measures were validated sexual function questionnaires and visual analogue scales (VAS). We identified and assessed 1925 original articles; 18 articles were included...
