Brief 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.

Outcome Measures
Primary Outcomes (4)
Sperm count
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.
Baseline and 9 months
aspermia (A)
Aspermia is determined by the ratio of the difference of total spz between before surgery and after surgery on the number of spz before surgery
Baseline and 9 months
retrograde ejaculation (R)
retrograde ejaculation is determined by the difference in percentage of retrograde ejaculation between postoperative and preoperative
Baseline and 9 months
Evaluation of the coefficient C
A and R will be subtracted to obtain the coefficient C
9 months
Secondary Outcomes (6)
Type of surgery
9 months
Preoperative prostate volume

Changing in urinary output before and after surgery
Baseline and 9 months
Evaluation of urinary symptoms questionary (IPSS) before and after surgery
