Summary

Every year in France, more than 60 000 people are operated for benign prostatic hyperplasia (BPH). This surgery is accompanied by a change or even a loss of ejaculations externalized what constitutes the main constraint for patients. Empirically, the investigators talk to the patient "retrograde ejaculation" to explain a possible loss of ejaculation. Yet the underlying mechanism of this modification or loss of ejaculation remains completely unknown. Yet the underlying mechanism of this modification or loss of ejaculation remains completely unknown. No study could not determine whether the predominant mechanism was a real retrograde ejaculation or aspermia. Moreover, technical changes are sometimes tempted to preserve antegrade ejaculation but no scientific rationale can not validate.

• Benign Prostatic Hyperplasia

Interventions

Type	Name	Description
PROCEDURE	Search retrograde ejaculation	Sperm count (spz) after orgasm achieved by masturbation will be measured, corresponding to the sum of spz collected in the ejaculate (E) and the first urine after orgasm (U). These measures will be made before surgery (E1 and U1) and after surgery (E2 and U2). The values E1, E2, U1 and U2 will be achieved by multiplying the concentration of spz per unit volume by the total volume of collection.
