A woman’s fertility declines after she turns 35. The probability of achieving a pregnancy naturally is only approx. 5-6% when the woman turns 40, and at the same time the risk of spontaneous abortions increases.
What factors affect a pregnancy?
The woman’s age is one of many risk factors for pregnancy. Other risk factors for a pregnancy are:
Chronic diseases such as diabetes or arthritis.
Metabolic diseases.
Unhealthy lifestyle (poor diet, too little exercise).
