Live Birth
No significant IVF, perinatal differences with embryos from donor, autologous oocytes
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.
IVF live birth rate lower with deep infiltrating endometriosis, endometrioma
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.
Shorter, longer interpregnancy intervals tied to spontaneous abortion risk
After a healthy live birth, interpregnancy intervals shorter than 18 months or 36 months or longer were associated with an increased risk for subsequent spontaneous abortion, according to cohort study results published in JAMA Network Open.
Long-term embryo storage not tied to live birth rate after frozen embryo transfer
Long-term embryo cryopreservation was not associated with live birth rates for women undergoing elective or nonelective frozen embryo transfers, according to an analysis published in the American Journal of Obstetrics and Gynecology.
High live birth, low preterm delivery rates with gestational carriers
NEW ORLEANS — Live birth rate was higher and preterm delivery risk lower with gestational carriers, or surrogates, compared with assisted reproduction cycles not using a gestational carrier, according to study findings.
Controversial embryo screening method improves live birth rates
Preimplantation genetic testing for aneuploidy, or PGT-A, improved in vitro fertilization success rates and guarded against miscarriage, despite guidance suggesting that it is not effective or safe, according to researchers.
