Is post-natal growth during the first 2 years of life in IVF singletons affected by type of medium used for culturing human embryos during an IVF treatment? ⋯ W.V. was funded with an unrestricted research grant from the Stichting Fertility Foundation. The authors declare no conflict of interest.

Do paternal and maternal lifestyle factors influence the risk of hypertensive pregnancy complications, gestational diabetes mellitus (GDM), spontaneous preterm birth and small-for-gestational-age (SGA)? ⋯ Paternal lifestyle factors do not have an independent effect on the investigated adverse pregnancy outcomes. However, as paternal and maternal lifestyles are positively correlated, both partners should be involved in preconception counselling regarding the investigated outcome measures.

What is the prevalence in a normal population of polycystic ovary syndrome (PCOS) according to the Rotterdam criteria versus revised criteria including anti-Müllerian hormone (AMH)? ⋯ None.

What is the reliability of preimplantation genetic diagnosis (PGD) based on polar body (PB), blastomere or trophectoderm (TE) analysis in a heteroplasmic mitochondrial mouse model? ⋯ To avoid the transmission of heritable mtDNA disorders, PGD techniques should accurately determine the level of heteroplasmy in biopsied cells faithfully representing the heteroplasmic load in oocytes and preimplantation embryos. Unlike previous PGD studies in mice, our results accord with PGD results for mitochondrial disorders in humans, and question the reliability of PGD using different stages of embryonic development.

Does the interaction between integrin and its ligand osteopontin (OPN) mediate embryonic attachment to endometrial epithelium at implantation? ⋯ No external funds were used for this study, which was supported by funds from the Universities of Manchester and Oxford. None of the authors has any conflict of interest to declare.
