Problems with conceiving? Some researchers say that improper footwear might be contributing to the issue, particularly high heels. Shoes with a heel, especially a heel over five inches high, impact a woman's posture. High heels force the lower back outwards, causing a forward tilt in the pelvis. With the pelvis at an awkward angle, the inner organs tend to get squished together in an unnatural manner. Some scientists believe this may cause some damage to the female reproductive system because this can slow down the gastric functions which leads to menstrual dysfunction and can ultimately impair fertility. It is not likely that high heels will disappear from the fashion scene any time soon, they are a favorite staple of many designers. But if you are looking to conceive any time soon perhaps a switch to flats might be a better option. It will prepare you for the future when you will lead a life on the run as you trail after your toddler.
