Infertility Factors vs. IVF: Key Contributor to Birth Defects

A Seminars in Fetal & Neonatal Medicine study reveals 20% of birth defects in subfertile couples occur even without IVF, compared to IVF-related ART risks at 30%. The research concludes infertility’s biological factors are the primary driver, not IVF protocols themselves.

Thawed Embryo Transfers Reduce Multiple Pregnancy Risks

Choosing thawed embryo transfers over fresh cycles lowers multiple gestation risks by 15%. This method allows embryo culture and selection, improving implantation rates while reducing the need for embryo splitting in multiple births.

IVF Advantages for Women with Blocked Tubes, Male Infertility, or PCOS

IVF offers 40% higher pregnancy success rates for women with tubal blockages compared to natural conception. For male infertility cases, intracytoplasmic sperm injection (ICSI) achieves 50% fertilization rates. Women with PCOS benefit from IVF’s controlled ovarian stimulation protocols.
