Higher obstetric complications, twin births with delayed embryo transfer during IVF

Elvira Manzano, 20190801141000

Delaying the transfer of embryo until the blastocyst stage during in-vitro fertilization (IVF) increased obstetric complications and twin births in a Nordic study. This finding is particularly important as there’s a spike in assisted reproduction technology (ART) treatments being performed with blastocyst transfer (BT) in recent years, according to the investigators.

No benefit of ICSI over IVF in non-male factor infertility

Roshini Claire Anthony, 20190725140302

Patients undergoing assisted reproduction for non-male factor infertility do not derive greater benefit from intracytoplasmic sperm injection (ICSI) over in vitro fertilization (IVF), according to a study presented at ESHRE 2019.

Frozen, fresh embryo transfers yield similar growth outcomes

Elaine Soliven, 20190723093639

Children who were born after frozen embryo transfer (FET) showed comparable growth outcomes during their first 5 years of life as those who were born after fresh ET, according to a study presented at ESHRE 2019.

Long-term sperm cryopreservation does not affect pregnancy success

Roshini Claire Anthony, 20190722140303

Likelihood of pregnancy following artificial insemination by donor (AID) or in vitro fertilization (IVF) was not negatively affected by using sperm that had been cryopreserved for up to 15 years, according to a study from China.

Immediate frozen embryo transfer improves pregnancy, live birth rates

Elaine Soliven, 20190719093300

Women who underwent immediate frozen-thawed embryo transfer (FET) following a stimulated in vitro fertilization (IVF) cycle were more likely to have ongoing pregnancy and live birth compared with those who underwent delayed FET, according to a study presented at ESHRE 2019.

New study questions widespread use of freeze-all strategy in IVF

Pearl Toh, 20190718190000

The increasingly adopted strategy to freeze all IVF* embryos for transfer in a later cycle offers no improvement in ongoing pregnancy rates over the conventional strategy of fresh embryo transfer among normo-ovulatory women, thus calling into question a general freeze-all strategy in a growing number of clinics.

Increasing paternal age may reduce IVF/ICSI success rate

Roshini Claire Anthony, 20190718140203

The likelihood of pregnancy following in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is significantly reduced when male partners are aged 51 years and older, according to a retrospective study from the UK.

Exposure to prenatal paternal smoking tied to lower sperm count

Paternal smoking exposure tied to lower sperm count in male offspring

Pearl Toh, 20190715190000

In addition to the known evils of maternal smoking during pregnancy on the sons' semen quality, prenatal exposure to paternal smoking can also be harmful, according to data from the large Danish National Birth Cohort (DNBC) presented at the ESHRE 2019 Meeting.

Myo-inositol improves quality of oocyte, embryo in ART-treated women with PCOS

Audrey Abella, 20190712100000

Women with polycystic ovarian syndrome (PCOS) undergoing assisted reproductive technology (ART) cycles may benefit from the administration of myo-inositol (MI) which improves oocyte and embryo quality due to alterations in gene expression in granulosa cells, according to a study presented at ESHRE 2019.
