It is common to use the term unexplained infertility for such cases. Empirical hormonal treatment of the male partner (even in those with normal gonadotropin levels) is sometimes reported to be effective in restoring fertility. The reasons for this are unknown, but it may be that, in some of these patients, the natural hormones are themselves defective and therefore fail to stimulate the testes adequately. Empirical treatment may also sometimes be successful in patients with oligospermia or impaired sperm motility, for whom no other more specific treatment is indicated or available.
