Numerous studies have addressed this question, each with its own strengths and weaknesses. From my perspective, the most useful studies are those that identify women with PCOS and follow them forward (cohort studies) to see if the risk of miscarriage is greater compared to women without PCOS. One closely followed group of women are those undergoing assisted reproductive technologies (ART), as clinics are required by law to monitor the outcomes of IVF cycles.

Many couples have concerns about the effects of age and fertility. Reproductive aging has become an increasingly important issue as our society has experienced longer life expectancy, advances in assisted reproductive technology (ART) and a changing role for women.
As noted in an earlier blog Age Related Decline in Female Fertility, maternal age significantly influences pregnancy outcomes, with maternal fertility peaking between the ages of 22 and 26 years and starting to decline around the age of 32 years. The progressive decline in fertility is caused by a loss of both the quantity and quality of the remaining eggs. Consequently, women experience an age-dependent increase of miscarriages, obstetric complications and chromosomal abnormalities of the fetus (Down’s syndrome for example).
I cannot stress enough the negative impact of female aging on reproductive outcomes. Every day that I see patients in the clinic, I discuss the importance of the age-related decline in female fertility. I typically describe this as a case of "cruel biology," because for women, unlike for men, the passage of time is a treacherous adversary in terms of achieving a pregnancy and building a family.
Modifiable lifestyle practices have an important impact on a couple’s chances of having a healthy child. Diet, weight and other lifestyle habits, including alcohol consumption and caffeine intake, have been shown to directly impact pregnancy chances.
