"If the ovaries were removed between the start of pregnancy and the second month then.....because....."

"If the ovaries were removed after the second month....."

I'm confused because I thought that once pregnancy begins, no more ovulation occurs until pregnancy is over. So I assume the ovaries don't play a role in pregnancy. And so if they were removed (no matter what time after pregnancy), shouldn't there be no effect?

Oh! Does it have something to do with the loss of the corpus luteum? If the CL is gone, then no estrogen/progesterone would be produced. These hormones are essential for pregnancy, and so the removal of ovaries would lead to...the loss of the pregnancy...or abnormalities?

Also, I'm thinking that in the first question, there wouldn't be as much effect because estrogen/progesterone levels are not really that high anyways. But after 2 months, the levels increase significantly, and so loss of pregnancy/abnormalities would be the result.

Am I thinking about this correctly?

You are correct that during pregnancy, ovulation does not occur. Once fertilization occurs, the fertilized egg implants into the uterus and begins developing into an embryo. The ovaries primarily produce eggs and release hormones necessary for conception, but they are not directly involved in the development or maintenance of pregnancy after implantation.

If the ovaries were removed between the start of pregnancy and the second month, it would likely have minimal effect on the pregnancy. By this point, the embryo is already implanted in the uterus, and crucial pregnancy hormones, such as human chorionic gonadotropin (hCG), are being produced by the developing placenta. So, even if the ovaries were removed during this early stage of pregnancy, the pregnancy could still progress normally.

If the ovaries were removed after the second month, once again, it would not directly impact the existing pregnancy. By this time, the placenta has taken over the production of hormones required to sustain the pregnancy. However, the removal of the ovaries would lead to permanent infertility, as the eggs stored in the ovaries would no longer be accessible for fertilization.

So, while the removal of the ovaries during pregnancy may not directly affect the ongoing pregnancy, it will have long-term consequences for fertility. It's essential to consult with a healthcare professional to discuss the potential risks and implications of such a procedure.
