[Value of prostaglandins in andrology]

In humans, the highest concentration of prostaglandins is found in the seminal fluid, where they are stored. They probably act as hormones by exercising--via receptors--an influence on cell function. Views on the role of prostaglandins in fertility vary. An explanation for this may be the methodological differences discussed. It remains for future research to establish the true functions of this highly versatile class of compounds in the area of fertility.
