RESUMEN
Studies have been made on the semen of three categories (borderline, borderline tuberculoid and lepromatous) of leprosy patients to evaluate the seminal biochemical constituents viz. fructose, glycerylphosphorylcholine and acid phosphatase besides the physical properties viz. volume, pH, liquefaction time, sperm density and sperm motility. In all categories of leprosy patients, seminal pH, liquefaction time and sperm density underwent significant decline. The decline in the seminal volume and sperm motility was significant only in borderline leprosy. It was observed that seminal glycerylphosphorylcholine (GPC) concentration and acid phosphatase activity declined in all categories of leprosy patients but GPC showed a significant decline only in borderline tuberculoid and acid phosphatase declined significantly only in borderline and lepromatous leprosy.
