Testing the Man
Testing on the man focuses on the number and health of his sperm. The lab will look at a sample of his sperm under a microscope to check sperm number, shape and movement. Blood tests also can be done to check hormone levels. More tests might be needed to look for infection or problems with hormones. These tests can include:
- X-ray (to look at his reproductive organs)
- mucus penetrance test (to see if sperm can swim through mucus)
- hamster-egg penetrance assay (to see if sperm can go through hamster egg cells, showing their potential to fertilize human eggs)
Other tests can show whether sperm and mucus are interacting in the right way or if the man or woman is forming antibodies that are attacking the sperm and stopping them from getting to the egg.
