Evaluation of the infertile couple.

Infertility may be caused by gross pelvic pathology, difficulties with insemination of the cervix and uterine cavity, partial or complete occlusion of the fallopian tubes, female endocrine abnormalities or male factors. Some forms of pelvic pathology as well as some tubal occlusions are amenable to surgical correction. Clomiphene citrate has given good results in some patients with endocrine abnormalities.
