Potential markers of epididymal function include carnitine and glycerol phosphocholine. Sperm take approximately two weeks to get through the epididymis. Sperm are stored near the tail portion and in the vas deferens until they are ejaculated. Accessory organs Seminal vesicles Contribute prostaglandins and fructose. Contribute two-thirds of volume of ejaculate.
Qualitative fructose is useful for verifying presence and the presence of the vas deferens.
Prostate Contributes acid phosphatase, Zn and citric acid. Chronic inflammation may contribute to infertility. Two or more complete semen analyses Should evaluate volume, agglutination, viscosity, quantitative motility and morphology, count, viability and membrane quality. Laboratory improvement of sperm with insemination Can make semen quality better with lab manipulation techniques and then utilize with intrauterine insemination. Serum FSH levels provide an important diagnostic parameter in determining the pathological basis of azoospermia.
