Background: Cabergoline is effective in the treatment of hyperprolactinemic hypogonadism. It is a highly effective and long-acting inhibitor of prolactin secretion. The rate of cabergoline-induced pregnancy in women with prolactinoma, is unknown. Objective: The aim of present study is to evaluate the efficacy and safety of high-dose cabergoline therapy for hyperprolactinemic infertility among Bangladeshi women. Method: This descriptive cross- sectional study was conducted among 50 patients from January, 2020 to January, 2022 in at The Medinova Diagnostic Centre, Sylhet, Bangladesh. Results: In our study, maximum (14) patients belong to the age group of 19 to 23 years, and minimum number of patients (4) was between 39 to 43 years. Maximum (52%) patients had the primary infertility and 48% had secondary infertility. The mean values of thyroid stimulating hormone (TSH), Follicle-stimulating hormone (FSH), luteinizing hormone (LH) and prolactin PRL is 3.93±6.58, 10.96±13.58, 9.83±6.8, and 12.46±14.39 respectively and these were significant. 12% patients had PCO and 88% patients were normal in our study. 78% semens were normal, 4% semen showed Azzospermia, 14% semens showed Oligo Astheno Spine and 4% semens showed Astheno spine. Conclusion: In infertile women with prolactinoma, cabergoline can achieve a high pregnancy rate with uneventful outcomes. The findings demonstrated that cabergoline can be used safely to improve menstrual cycles in hyperprolactinemia.
