    Why do the testicles of male hang outside their body? 

    If you are a male did you ever wonder why god kept the testicles (or testis) outside your body, hanging in a pouch or sac like thing called scrotum.

    Obviously that outside hanging position makes them vulnerable to injuries when hit accidentally or kicked by someone deliberately, as frequently seen in movies and also in real life.

    What would have happened if god had kept these two male ornaments inside the frame of the main male body rather than hanging outside?

    Testicles are responsible for producing sperms. Human body temperature is much higher than what is required for sperm production and sperm survival. Therefore, if testicles were inside male’s body he would have been impotent because of defective or no sperm production. Since the testicles hang outside male’s body it’s not affected by the body heat directly and the air circulating around the scrotum keeps the testicles cooler, in comparison to the temperature of the body. This ambient temperature maintenance system allows sperm’s formation and survival. Sperm formation is also referred as spermatogenesis.

    This same logic explains why tight underwear of male are discouraged? Tight underwear’s bring the testicles close to the body which raises the temperature inside to scrotum and testicles might find it unsuitable for spermatogenesis.

    Another interesting phenomenon is the testicles moving closer or away from body due to variation of environmental temperature. At cold winters males testicles are drawn near to the body to protect sperms from the harsh cold, here they use body temperature to protect sperms from the cold.

    That’s all for this edition in sex topic.

      Hello Doctor saha
      I had a question I couldn’t find the answer anywhere!
      Q: Does it affect the production of testosterone by testicles if someone set them inside the body by surgical action (on purpose)?

        It would decrease the functions of testicles because the raised body temp of our body wouldn’t allow its normal functioning. Moreover, the likelihood of cancer increases.

    Artificial fertilization methods can cause mental retardation 

    Today’s discussion is about, if artificial methods of fertilization used in infertile couples have any detrimental effects on the newborns. Interestingly small amount of increased risk of mental retardation is feared of to occur in the newborn, although risk of autism were almost excluded. The specific cause of such decreased mental capabilities are yet to unfold but proposed hypothesis is the need of traditional methods of at least 2 embryos implantation in utero, during the in vitro fertilization (IVF). More than one embryo implantation increases the risk of developing multiples like twins or triplets and this increased the chance of preterm or low birth weight problems. And these are already blamed for affecting mental functions sometimes. Henceforth, one embryo implantation instead might be a better solution.

    Some also suspect ICSI i.e. intracytoplasmic sperm injection (where a sperm is injected inside the cytoplasm of the egg), during this procedure, method of natural selection can’t take place since the sperm is chosen by humans rather than nature, which may not be the healthiest sperm. Whereas in IVF generally sperms are allowed to compete in a dish in lab to fertilize the ovum and mimic the natural process that takes place in internal reproductive organs of women.

    Cancer patients fighting infertility 

    Infertility stories aren’t uncommon in young male cancer patients. Although testicular cancer can affect the sperm health, cancers from other parts of the body don’t always spread to the testes but still the patient’s sperm quality might get affected and can cause infertility. Such harsh effect of sperm health is mainly because of the side effects of various treatment modalities used to treat cancer (for example chemotherapy).

    Now a new solution to protect fertility in cancer patients is probably encroaching in, if male cancer patients preserve their sperm via cryopreservation (i.e. preservation in sub zero temperature or cooling) before they start their cancer treatment they might be able to use those sperms later in life whenever they plan to be father by various assisted reproduction treatments.

    Although this new fertility preserving method in cancer patients might sound like common sense but probably the truth is that most scientific discoveries are a type of common sense, for example try thinking of Newton’s gravity discovery by virtue of an apple fall from tree.
