Non-surgical sperm retrieval is possible for those suffering from anejaculation or retrograde ejaculation, wherein ejaculation can be induced. The semen is then collected. Via, two possible methods:
Penile Vibratory Stimulation (PVS)
Penile vibratory stimulation is accomplished using a special vibrator that is placed at the tip of the penis. The penis is then stimulated for the ejaculate, and this is then collected to retrieve sperm.
The electroejaculation method uses a probe that sends electrical energy to the prostate and seminal vesicle. This is a method used for men with injuries and who do not have any sensation. However, even those men who have normal sensation can opt for this procedure under general anaesthesia.
