When a woman has a retroverted uterus, this means that her uterus is not facing up and down like normal. Instead, it has been tipped, typically towards the stomach. In the past, it was believed that this condition meant that it was harder for a woman to become pregnant, but this is not always the case.
Typically, when a woman is struggling to become pregnant, it is usually the sign of a secondary medical issue. For example, issues like endometriosis can actually cause scar tissue that will tip the uterus. This condition can make it harder to conceive.
However, there are some positions that can help make it easier for a couple to conceive. For example, having intercourse in the rear entry position can make it easier for the sperm to get into the uterus where the egg is. You can also try lying flat on your stomach for several minutes after intercourse.
It can also be helpful to have intercourse with the woman on top. This can help put the sperm in the right position to help it reach the egg easier. It can also be helpful to have intercourse that is shallow can help put the sperm in the right location. As always, it is best to lie still for 10-15 after intercourse.
