It takes ten times longer to conceive at 43 than at 37 – doctors say

Women who delay starting a family have been warned that it is ten times harder to get pregnant at age 43 than at 37.

Researchers found that, on average, a 37-year-old needs to produce 4.4 eggs for one normal embryo – but at 43, there’s an astronomical rise to 44 eggs.

​Researcher Dr Meredith Brower (of the University of California, Los Angeles,USA) told a conference that the number of eggs needed for a viable pregnancy rises ‘almost exponentially’ after 42, and urged women to freeze their eggs without delay.​
