Prolactin Deficiency is a condition where the body produces insufficient levels of the hormone prolactin. This hormone is primarily responsible for stimulating milk production in breastfeeding women and plays a role in regulating various reproductive functions. Low levels of prolactin can lead to issues such as difficulty breastfeeding and irregular menstrual cycles. Symptoms of prolactin deficiency may include reduced milk supply, infertility, and changes in libido. Diagnosis typically involves blood tests to measure prolactin levels, and treatment may include hormone replacement therapy or addressing underlying causes. Early detection and management are important for overall reproductive health.
