Why do testicles retract?
Testicles are organs distinct only to men. As a component of the reproductive system and the endocrine system, testicles specifically function in the production of sperm cells and androgens or male hormones. Greatly influenced by gonadotropic hormones coming from the stimulation of the anterior pituitary gland, the production of sperm, also known as spermatogenesis, takes place. For male individuals, the testes are often contained within an extension of the abdomen called the scrotum. It has been observed that the left testis is usually higher compared to the testis on the right. However, others claim that they have equally positioned testicles. This is due to differences in the vascular anatomical structure on the right and left sides. Contained within the scrotum are significant parts that play vital roles in maintaining normal body functions, especially in the reproductive and endocrine systems.
For the majority of boys and men, their testicles will remain dangling where they left them. However, there are instances when the testicles tend to retract, providing some considerations to the presence of several factors such as temperature of the environment and the body. When the testicles do their disappearing act, they are being pulled by a muscle in the groin called the cremaster. Testicles retract when one feels cold, to maintain the required temperature for sperm cells to viable, when one is anxious or one is close to orgasm either through intercourse or masturbation. The retraction of the testicles is one normal occurrence that only men can experience. For most teenagers and boys, this often leads them to wondering why such mechanism takes place.
Although the retraction of testicles is part of the male humans’ nature, if one or both of your testicles do not return to their natural position, medical attention should then be sought.
