I'm 50 years old and i still would like to have a child but my ob-gyne discouraged me. what is your advice?

Depends on situation: Any pregnancy has at least 4% risk of unexpected issues, includeing birth defects, prematurity or other problems. To that basic risk you must add that of your health & the increased in chromosome defects with age.At 50 your Down syndrome risk rises to 10%. The ds kid has a potential lifespan of 6+decades of supervised care. With at least a 14% risk of problem & long lasting issues, consider all 1st.
