Infertility: What are the causes? Dr. John A. Schnorr: Primary infertility, many many causes. We know that primary infertility can be inadequate timing of intercourse. It can be low sperm counts. About 40% of all cases of infertility are due to male factors; which is the sperm counts low. It could be that the cervix has an abnormality and the sperm aren't able to swim up through the cervix and get into the uterine cavity. It could be that the uterus has a structural abnormality, such as fibroids. It could be that we have blocked fallopian tubes, that's the connection between the uterus and the ovary has a tube called the fallopian tubes, one on each side, they could be blocked and that could make it so that you can't get pregnant. Then you can have other thing such as the ovary is not working well. Maybe they are just not ovulating this plenty of eggs but they are not ovulating every month, or it could be that there is no more eggs left and that's why they are not ovulating every month. We also have common disorders called endometriosis, and scar tissue can happen inside the thalamus. So we now know probably 50 different causes of infertility. Secondary infertility: Secondary infertility similar causes, but we start thinking about what changed. The case you were able to conceive before but now you are not able to conceive, what's specifically changed? Did you have an infection since you had your child? Did your husband have testicular injury or testicular trauma since you had your last child? Are you still having a regular menstrual cycle since you had your last child? Are you having hot flashes, vaginal dryness, signs of menopause, variety of different things we can look at. So we are more focused on a change in secondary infertility than we are with primary infertility.
