What are the types of non-surgical extraction available?
Non-surgical sperm retrieval is possible for those suffering from an ejaculation or retrograde ejaculation, wherein ejaculation can be induced. The semen is then collected. Via two possible methods:
- Penile Vibratory Stimulation (PVS) : A 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.
- Electroejaculation (EEJ) : 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.
If PVS or EEJ don’t work, a sperm retrieval method from the epididymis or testicle may be needed.
