Prevalence of hyperprolactinemia among infertile patients with menstrual abnormalities and/or galactorrhea at a University Teaching Hospital, North West Nigeria

Objective: Hyperprolactinemia may be associated with galactorrhea, menstrual abnormalities, and infertility. When diagnosed and appropriate treatment instituted, there may be early relief of these symptoms and pregnancy rate may increase. This study determined the prevalence of hyperprolactinemia among infertile patients with menstrual abnormalities and/or galactorrhea. Patients and Methods: A cross-sectional study of women attending the infertility clinic who had galactorrhea and/or menstrual abnormalities. Menstrual abnormalities for this study refer to those with oligomenorrhea and amenorrhea. Results: Out of the 207 women studied, 75 of them have hyperprolactinemia, giving a prevalence of 36.2%. Galactorrhea has higher sensitivity (68%), a higher positive predictive value (39.5%), and a higher negative predictive value (69.3%) when compared with menstrual abnormalities which had sensitivity of 44%, positive predictive value of 29.7%, and negative predictive value of 56.3%, respectively. They, however, have the same specificity of 40.9%. Conclusion: The prevalence of hyperprolactinemia is high in this study. Galactorrhea is a better clinical indicator of hyperprolactinemia when compared with menstrual abnormalities.
