Psychosocial and physical wellbeing in women and male partners undergoing immediate versus postponed modified natural cycle frozen embryo transfer after ovarian stimulation and oocyte pick-up: a sub-study of a randomized controlled trial.

Study Question: Are there differences in psychosocial and physical wellbeing among women and male partners undergoing modified natural cycle (mNC) frozen embryo transfer (FET) in immediate compared to postponed cycles after ovarian stimulation (OS) and oocyte pick-up (OPU)?

Summary Answer: Significantly more women in the immediate group reported physical symptoms than women in the postponed group whilst fewer were emotionally affected by waiting time, although the latter difference lost statistical significance after adjustment for multiple testing.

What Is Known Already: Infertility and fertility treatment are known to cause psychosocial distress in women and couples longing for a child. The treatment may be long-term and delayed for various reasons, such as the elective postponement of FET after a fresh transfer without pregnancy or an elective freeze-all cycle, possibly further increasing the level of distress.

High sperm deoxyribonucleic acid fragmentation index is associated with an increased risk of preeclampsia following assisted reproduction treatment.

Objective: To study the association between sperm deoxyribonucleic acid fragmentation index (DFI) and the odds of preeclampsia and other adverse perinatal outcomes after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment.

Design: A prospective cohort study including infertile couples undergoing conventional IVF or ICSI treatment and their children. Data regarding preeclampsia and perinatal outcomes were derived from the Swedish National Birth Register.

Progesterone concentrations on blastocyst transfer day in modified natural cycle frozen embryo transfer cycles.

Research Question: Are serum progesterone concentrations on the day of modified natural cycle (mNC) frozen blastocyst transfer (FET) without luteal phase support (LPS) associated with clinical pregnancy rate (CPR)?

Design: Data were collected between January 2019 and October 2022 as a sub-study of an ongoing randomized controlled trial assessing pregnancy outcomes in mNC-FET. The sub-study included all women (n = 209) randomized to mNC-FET without LPS at the time of data extraction. Participants were aged 18-41 years, had regular menstrual cycles and underwent mNC-FET treatment with single-blastocyst transfer.

Single mothers by choice - experiences of single women seeking treatment at a public fertility clinic in Denmark: A pilot study.

Problem: There has been an increase in the number of single women deciding to have children through the use of medically assisted reproduction (MAR). These women are referred to as 'single mothers by choice' (SMC).

Background: Previous studies have shown how SMC can feel stigmatised.

The prevalence of late-follicular phase progesterone elevation and impact on the ongoing pregnancy rate after fresh and frozen blastocyst transfer. Sub-study of an RCT.

The effect of late-follicular phase progesterone elevation (LFPE) during ovarian stimulation on reproductive outcomes in ART treatment remains controversial, but recent studies indicate lower pregnancy rates with rising progesterone levels. This study aims to investigate the prevalence of late-follicular phase progesterone elevation (LFPE) and possible impact on ongoing pregnancy rate after fresh or frozen blastocyst transfer in a sub-study setting of a randomised controlled trial. A total of 288 women were included (n=137 and n=151 in the fresh transfer and freeze-all group, respectively).
