Pituitary tumors often have many ways to classify, which include hypersecreting (hyperhormonal) and non-hypersecreting (not related to hormones). Usually, the problem with infertility comes from a prolactin-secreting pituitary tumor.
More specifically, tumors that arise from prolactin-secreting cells will increase the production of this hormone in the blood many times. This will interfere with fertility in both sexes:

When FSH is low, the patient is likely to have polycystic ovaries, difficulty in ovulating and leading to difficulty conceiving. LH: LH hormone stimulates the production of Estradiol in the ovaries.
