Background Platelets contain a significant amount of growth factors that have positive effects on local tissue repair and endometrial receptivity. Case Here we present a 45-yr-old woman with primary infertility and two failed in vitro fertilization (IVF) cycles who was candidate to receive donor eggs. Five consecutive frozen-thawed embryo transfer cycles with good quality embryos were perform...

This study in Turkey evaluated the impact of age-based mandatory single-embryo transfer (SET) legislation with the subsequent increase in frozen-thawed embryo transfer (FT-EU) on pregnancy outcome of in vitro fertilization (IVF) patients. SET, FT-FT and double-embryo transfer were used in 5632 patients after legislation, while traditional IVF and FT-FT approach was used in 6029 patients before ...

STUDY QUESTION Are childhood measures of phenotype associated with peri-conception parental, IVF treatment and/or embryonic characteristics of IVF children? SUMMARY ANSWER Birthweight, childhood body mass index (BMI) and height of pre-pubertal IVF children were strongly associated with peri-conception factors, including follicular and embryonic characteristics. WHAT IS KNOWN ALREADY A growi...

BACKGROUND The timing of embryo transfer (ET) after in vitro fertilisation (IVF) remains controversial, and there are no reliable guidelines available to prospectively identify which patients would benefit from either day-3 or blastocyst transfer. While blastocyst transfer is generally favoured over day-3 transfers, very few IVF patients get both in the same treatment cycle. CASE DESCRIPTION ...

BACKGROUND Assisted hatching (AH) in fresh embryo transfer (ET) cycles increases the implantation and pregnancy rates, especially in women with a poor prognosis, repeated implantation failures and in older women. Little information exists in the literature regarding the role of AH in frozen-thawed embryo transfer (FET) cycles. METHODS Embryos were cryopreserved at the cleavage stage. On the d...
