Why not just use a surrogate instead? That's what every one of my friends who faced infertility, did.

A few reasons I can think of, having been through IVF twice now:

- Capability. Many couples are perfectly capable of carrying a pregnancy, they’re just having trouble conceiving.

- Cost. Surrogacy in a lot of countries is very expensive compared to IVF. Where I live in the UK, IVF is free on the NHS, or ~£8,000-£10,000 a round privately. Surrogacy can be £20,000 to £100,000 (or more), depending on the arrangement.

- Legal issues. In the UK, for example, the surrogate mother is the legal mother of the child at birth.

- Availability. Finding a surrogate can be very hard, especially in countries where commercial surrogacy is illegal. People go use surrogates abroad instead, which has its own range of issues (read up on orphaned surrogate kids in Ukraine).

- Ethical barriers. Using a surrogate involves issues of bodily autonomy. You can’t stop your surrogate smoking or drinking while pregnant, for example.

- Emotional barriers. Emotionally, motherhood starts at conception. Most mothers do not want to skip those 9 months of bonding they have with their baby prior to it being born.
