Surrogacy at an advanced age comes with increased risk

DEAR DR. ROACH »

Would you please comment on common or uncommon issues that might be expected in a pregnancy at age 57? I am overall very healthy, with no issues other than slightly elevated LDL. I have not gone through menopause. I had four full-term pregnancies, the last at age 35 (after which I had my tubes tied), and no miscarriages. I asked my doctor two years ago if I would have an issue being a surrogate and was told there was no reason I couldn’t be, but my current physician told me that it can be very dangerous at my age. I’d like the real truth regarding any potential issues I would be likely to encounter. I appreciate your thoughts. — M.V.

DEAR READER » I admire your willingness to consider being a surrogate. However, the risks of pregnancy in a 57-year-old woman are significant.

A study from the U.K. from 2016 quantified the risks pretty thoroughly; however, of the 233 women studied, only two of them were older than 57, so your risks are probably higher than the average risk for an older mother in the study (which was defined here as 48 years or older at the date of delivery).

Compared with younger mothers, older mothers have a higher risk for: high blood pressure during pregnancy (15 percent vs. 5 percent); pre-eclampsia, also called toxemia (6 percent vs. 2 percent); diabetes during pregnancy (18 percent vs. 4 percent); hemorrhage after delivery (26 percent vs. 15 percent); Caesarean section (78 percent vs. 33 percent); preterm delivery (22 percent vs. 8 percent); and admission of the baby to the intensive care unit (3 percent vs. less than 1 percent). Miscarriage rate (after 11 weeks) in women over 55 is estimated to be about 10 percent, compared with 1 percent in younger women.

Overall, these risks are not small. You should think through your risks before making a decision. I’m disappointed in the lack of advice you received.
