How does the human reproductive system function? Learn about the male reproductive organs. The normal anatomy of the testicle and epididymis. Testicle dimensions and weight. Healthy testicles - appearance and structure, and microscopic images. What is the scrotum? Why is the left testicle larger than the right? Gentlemen, get your scrotum in hand! Let's examine your testicles! Urologist Krzysztof Sobkowiak encourages you to examine your testicles. Testicular function - sperm and testosterone production. Spermatogenesis - the process of sperm formation. Sperm maturation takes place in the epididymis. Ejaculation - where does sperm come from? How does the male reproductive system function? The impact of the testicles on male fertility and infertility. Male infertility is a growing health problem. The testicle is also an endocrine gland that secretes male sex hormones. Testosterone - the most important male sex hormone. Testosterone deficiency - hypogonadism. Symptoms of hypogonadism include: Erectile dysfunction - impotence, decreased libido, decreased semen quality, male infertility. The testicle is an important endocrine gland. Learn about the significant hormonal impact of androgens on the male body. A normally built man has two testicles, which, along with the epididymis, are located in the scrotum. The scrotum is a sac of skin and muscle that contains the testicles. The left testicle is usually slightly larger than the right. The left testicle usually lies slightly lower. This allows both testicles to better fit between the thighs. How much does a testicle weigh? The weight of a testicle, including the epididymis, is 20-30 grams. Normal testicle size: The size of a healthy testicle - The length of the testicle is 4-5 cm, the width of the testicles is 2.5-3.5 cm, and the thickness is 2 cm. The testicular flesh is composed of approximately 200 conical lobules. Within the lobules lie the seminiferous tubules, where spermatogenesis—the process of sperm formation—occurs. Each lobule gives rise to a collecting duct, and the system of these collecting ducts forms the rete testis. Sperm then reach the epididymis. The epididymis is a separate organ where sperm maturation occurs. The epididymis rests on the posterior-upper surface of the testicle. It is divided into three parts: the head, the body, and the tail. The epididymis not only stores sperm but also matures here. During ejaculation, sperm from the epididymal duct enter the vas deferens. They combine with secretions from the seminal vesicles and the prostate. Sperm exit the male body through the urethra as ejaculated semen. Testosterone is the most important male sex hormone. It is produced in the testicles by the interstitial Leydig cells. How does testosterone work? In utero, it is responsible for the development of male reproductive organs. Testosterone during puberty contributes to the development of a masculine physique and hair pattern, as well as a deepening of the voice. Testosterone stimulates sperm production, increases libido, and positively influences the occurrence of penile erections. Testosterone deficiency leads to hypogonadism. Symptoms of hypogonadism include libido disorders, impotence (erectile dysfunction), decreased semen quality, and male infertility. In short, it is the hormone testosterone that makes boys men.
