You mean like when your Pregnant?
Cat faeces can carry a parasite that causes toxoplasmosis, an infection that isn't serious for you but can pose a danger to your developing baby. Some birds and other animals, as well as some raw or undercooked meats, can also carry the parasite. Toxoplasmosis causes most severe damage to the fetus if a woman comes down with it in her first trimester.
Happily, the odds of contracting toxoplasmosis during pregnancy are low, and if you've had it once, you can't catch it again. Wha's more, it's rare for a woman to be infected for the first time during pregnancy. If you live with cats, the likelihood is even higher that you've already contracted the disease and developed an immunity to it.
I've never heard of it affecting a womans Ovaries before though,
maybe someone else on here might have a better idea.
