High follicle stimulating hormone in males is rare clinically and may be caused by the following reasons: 1. Male hermaphroditism, malformation of the reproductive system, or pseudohermaphroditism can cause an increase in follicle stimulating hormone levels. This can be further diagnosed clinically by ultrasonography and hormone level measurement and treated accordingly. 2. Follicle stimulating hormone can also be increased due to the effect of some medications, which can cause follicle stimulating hormone increase in men. If it is caused by drug factors, it is clinically recommended to suspend the drugs to relieve the symptoms.
