For the most part, it’s safe to presume that a woman over the age of 40 has the mental and emotional maturity to be a surrogate. We have age limits because of physical health concerns.
Yes, lots of women get pregnant in their late 30s and even into their 40s. However, health risks increase substantially with advanced maternal age. We see higher incidents of miscarriage, premature labor, gestational diabetes, hypertension (high blood pressure), placental abruption, and pre-eclampsia, which can be fatal to both surrogate and baby.
In conclusion, any woman who is willing to give of herself by being a surrogate is a special human being. However, their willingness to do this should not supersede safety considerations. Agencies and clinics must always thoroughly screen potential carriers and adhere to age guidelines to ensure the best outcome for everyone involved.
