Intracytoplasmic Sperm Injection

Use of embryos from donor or autologous oocytes resulted in no significant differences in live birth, implantation, ectopic pregnancy and miscarriage rates, gestation duration or infant birth weight, researchers reported.

In Europe, use of medically assisted reproduction increased in 2021 compared with 2020, according to preliminary data presented at the European Society of Human Reproduction and Embryology annual meeting.

Live birth rates were lower for women with vs. without deep infiltrating endometriosis and/or endometrioma undergoing first IVF/intracytoplasmic sperm injection, according to study results published in Fertility and Sterility.

For women using IVF/intracytoplasmic sperm injection, SARS-CoV-2 infection within 10 weeks after embryo transfer may not negatively affect pregnancy, implantation and miscarriage rates, researchers reported.

Children born to women with infertility who utilized assisted reproduction methods had slightly higher risk for autism spectrum disorder, independent of fertility treatment used, according to study results published in JAMA Network Open.

Women who underwent assisted reproduction had a similar risk for developing multiple sclerosis as women who conceived without being exposed to assisted reproductive technology, according to a Danish register-based cohort study.

Researchers identified techniques and interventions implemented in embryo transfer that affect clinical pregnancy rates, and they specifically advised against post-embryo transfer bed rest.

For women undergoing assisted reproductive treatment, having a previous unilateral oophorectomy was associated with lower odds of pregnancy and live birth, according to a meta-analysis published in Fertility and Sterility.
