We’ve been getting a lot of questions about fertility tests and other predictors of fertility from our customers who’re preparing for their fertility treatment with Ovally. For the purpose of this post, we’re going to focus on women’s fertility and what is available to test it, though keep in mind that it’s only half the story. The one predictor of fertility that probably comes to mind for most of us is age. We could write a whole post about the controversies of age-related fertility decline but will focus on hormone levels and fertility tests here. Suffice it to say that some frequently cited data on age-related fertility decline are very old and come with all kinds of confounds, but there is well established evidence that pregnancy success rates for women needing treatment for fertility issues decrease significantly with age, while rates of miscarriage and chromosomal abnormalities increase. A few studies comparing natural conception rates of women in their 30s and 40s have also shown that conception rates decrease and time to conception increases with age.
