With reproductive technology, families may end up with more children than they wanted because it is more fertile. For example, Nadya Suleman (a.k.a. octomon) had 14 children using in vitro fertilization. This could cause issues with the women.
Reproductive clinics are expanding on the idea of preimplantation genetic diagnosis, which is similar to eugenics. It allows the parent to choose the gender and it helps prevent defects. It allows parents to slightly modify their soon to be children without giving the parent full control over customizing the baby.

Reproductive Technology is riskier than normal pregnancies. Women are prone to having a higher rate of multiple-birth pregnancies. This also increases risk of complications lke preterm deliver and preclampsia.
Some parents aren't able to have children themselves. Some women's wombs' are very hostile and will kill any sperm that try to penetrate the egg. By manually combining the sperm and the egg outside the womb and placing the fertilized egg in another women's womb that is safe for the embryo, the parents are given the chance to have a child in which they may not have, otherwise, been able to have.
In vitro fertilization is more expensive than regular births and could put families in dept. IVF prices range from $10,000 to $15,000 but averagly it is $12,000. Prices are set per attempt so if the first try doesnt work you must have a lot of money if you want to try again.
