My answer to Does making abs make it difficult for getting pregnant in women?
Answer by Connie b. Dellobuono:
Each person is unique. Fats in our bodies are important for pregnancy hormones to work. We know that a narrow pelvis would have difficult labor and childbirth. But exercise is always good in facilitating all bodily functions including childbirth. Stress will affect us in a way that it interferes in our sexual reproductive hormones. Fertility rates in men and women are the same and there is higher infertility in most industrialized countries. Stress and environmental toxins might be contributing to infertility. As we age, our bodies are not in tune to reproduce as our reproductive organs are aging.
