2) Ovulation disorders: Normal and regular ovulation, or release of a mature egg, is essential for women to conceive naturally. 8–16 One retrospective case-control study of 650 men with infertility and 698 control participants questioned the role of environmental risk; no association could be determined after assessing for multiple factors including shift work, stress, and pesticides.
