In recent years I have become increasingly aware of the phenomenon of feeling less strong, healthy, alert, (generally depleted) etc., following ejaculation. I have taken to refraining from ejaculation before important activities, athletic events, or when feeling run down and generally trying to limit the frequency of ejaculation. In this respect I often practice intercourse without orgasm or with orgasm without ejaculating. I know that in Chinese medicine this practice of limiting ejaculation, especially as one ages, is seen to have great health benefits and to maintain the level of IQ.
I am considering vasectomy and am wondering what effect it might have in this area? It is not really clear to me if it is the act of maintaining higher levels of sperm that is helpful, or just the seminal fluids themselves.On a related note-the practice I use of having orgasm without ejaculating involves squeezing the PC muscle very tightly during and after orgasm to suppress the release of semen-does vasectomy in any way compromise this? Thanks, Joe in North Carolina.
Lets start by reviewing some basic physiologic processes and definitions involved in sexual function. Erection, emission, ejaculation and orgasm. These four processes are coordinated but separate physiologic events during intercourse. Erection is the process of the penis becoming hard and is controlled by nerves and arteries to the penis. Emission is the process of fluid from your prostate, seminal vesicles and sperm depositing in the posterior urethra. Ejaculation is the coordinated contraction of the bulbospogiosus muscle (muscle surrounding the urethra), pelvic floor relaxation and bladder neck contraction. This propels the seminal fluid (which includes sperm) forward through the urethra and out the penis. Orgasm is a chemical signal released during ejaculation by the part of the brain involved with addiction. These four processes can occur independently or in concert. For example, a man without erections can still have emission, ejaculation and orgasm. Or, a man without emission can have erections and orgasm. A man can have an emission without ejaculating, like in the case of retrograde ejaculation (seminal fluid and sperm is propelled backwards into the bladder).
I am no expert of Chinese Medicine so I cannot comment on the utility of your technique to alter any one of these processes. However, it seems that you are preventing ejaculation (not emission) by contracting your external urethral sphincter and essentially causing yourself to retrograde ejaculate (back into the bladder). This is not healthy. The benefits of limiting ejaculation may be rooted in some mythical texts, but are not well supported by current medical literature. In fact, there is recent evidence to suggest that the more times a man ejaculates during his twenties and thirties (>21 times/month), the lower the risk of developing prostate cancer in the future. Ejaculation frequency and subsequent risk of prostate cancer. Leitzmann et all, 2004.
The sperm comprises only 5% of your total ejaculate volume. The remaining fluid comes from the prostate and seminal vesicles. Vasectomy only changes the sperm from reaching the ejaculate. Vasectomy does not cause any noticeable alteration in the ejaculate volume of men. I do not think you will notice any change in your practice of suppressing your ejaculation, if you should so desire to continue doing this.
