While ART can be highly effective, it is not without risks. Potential complications include: - Ovarian Hyperstimulation Syndrome (OHSS): A reaction to fertility medications that can cause swollen, painful ovaries. - Multiple Pregnancies: Higher chances of twins or triplets, which carry risks for both mother and babies. - Ectopic Pregnancy: An embryo implants outside the uterus, often in a fallopian tube. - Birth Defects: Slightly increased risk of certain birth defects compared to natural conception.
