Fertility Center of Dallas

Glossary Terms


A condition in which the thyroid gland produces an insufficient amount of thyroid hormone. The resulting lowered metabolism interferes with the normal breakdown of “old” hormones and causes lethargy. Men will suffer from a lower sex drive and elevated prolactin (see Hyperprolactinemia ), and women will suffer from elevated prolactin and estrogen, both of which will interfere with fertility.
