In women aged 40-44 years old using single embryo transfer (instead of double embryo transfer) may work better and decrease twins and other pregnancy complications.

Selective serotonin reuptake inhibitors (SSRI) are used to treat depression. SSRI use is associated with possible reduced infertility treatment efficacy as well as higher rates of pregnancy loss, preterm birth, pregnancy complications, neonatal issues and long-term neurobehavioral abnormalities in offspring. In the study: "The risks of selective serotonin reuptake inhibitor use in infertile women" the researchers found that infertile women do not benefit from using SSRIs.

Mothers who reported a fever without taking any medication to reduce fever during pregnancy were at higher risk to deliver a child that later developed autism. On the other hand, if they had a fever and took a medication to reduce fever, their child was not at higher risk. 

Is IVF assiociated with an increased risk of congenital heart disease? Assisted reproductive technologies (ART), and particularly intracytoplasmic sperm injection (ICSI), are specifically associated with a higher risk of tetralogy of Fallot (TOF), but not hypoplastic left heart syndrome, transposition of great arteries, or coarctation of the aorta.
