Question about testicles? |
Issue Whats the theory behind hardening and loosening of testicles........I was never able to understand my testicles.......... I mean when di they harden and when do they loosen........anybody knows..???? Best Tip The testicles are the organs used to produce sperm and are contained in a sac called the scrotum. The slightly strange thing about the testicles is that in order to function (ie produce viable sperm) they need to be kept at a fairly constant temperature that is BELOW normal body temperature. The muscular contractions and relaxations of the scrotum function to move the testicles nearer or further from your body so that they are kept at a reasonably constant temperature. When the scrotum contracts the testicles are pulled nearer to you and are warmed up - which is why you will note that they are "harder" when you (or they!) are cold. An ancient method of contraception (not to be reccomended) was for the guy to sit over a bucket of boiling hot water so that the heat killed the sperm. A more recent phenomenon is that guys who wear tight-fitting underwear that pulls their testicles close to their bodies have been found to have lower sperm counts because their body heat is killing the sperm. If you want a high sperm count then wear boxer shorts and loose-fitting trousers! Other factors may also induce this contraction - notably fear or a sudden burst of adrenaline. This is a normal response of pulling your vital sexual organs as close to your body as possible for maximum protection from injury (you also wouldn't want all that wobbling about if you had to run to escape from some danger). Some people, notably martial arts guys are supposed to be able to control the contractions of their scrotum - to the extent of retracting the whole package partly back into their bodies for protection. A very good friend of mine who was a Kung Fu instructor described this to me although I have never seen it demonstrated. Source(s): BSc Physiology & Biochemistry Others it's adjusting to the tempature of your body Sperm is very sensitive to temperature... So your nuts will harden to get warmer and loosen to cool down... All done to protect your little solders!! Tip 1. When the concrete is cured. Tip 2. When you degenerate into dust hopefully soon. Sperm are kept healthy and produced under a specific temperature that is lower than normal body temperature. Hardening and loosening will help regulate temperature so that you will have plentiful and healthy little soldiers! It is a matter of temperature control and ejaculation. Sperm is produced at a optimum temperature. Too cool and the scrotum tightens to bring the testes's closer to the body for warmth too warm and the testes's loosen to allow for cooling. Also at the time of ejaculation they tighten. |
