The testes are the primary reproductive organs and generate sperm cells v a procedure called spermatogenesis. The glands of the male reproductive system develop sperm and also seminal fluid. The prostate gland, the seminal vesicles, and the bulbourethral glands contribute seminal fluid to semen, i m sorry carries and protects the sperm. Throughout sexual intercourse, semen moves v a series of ducts to provide the semen straight into the female reproductive system.

1. The Testes develop Millions and also Millions the Sperm every Day


*

The testes (or testicles) are the masculine gonads and also sit below the dick within a sac dubbed the scrotum. They space 4-5 cm long, 2.5 centimeter in diameter, and covered v two membranous layers, the tunica albuginea and the tunica vaginalis. The testes generate sperm, the male sex cells, and testosterone and also other sex hormones. The production of sperm is constant and wake up within countless lobules in each testis. First, structures called seminiferous tubules create stem cells. These cells, the spermatogonia, divide into spermatocytes, and also then divide further to become spermatids. The procedure is referred to as spermatogenesis. Spermatids move from the testis come the epididymis and mature right into sperm.

2. Reproductive Ducts press Sperm and Semen v the internal Genitalia

*

The epididymis, vas deferens, ejaculatory ducts, and also urethra type a four-part transportation system. The epididymis sits straight on peak of every testis. Sperm native the testis mature together they move through the coiled duct the the epididymis. Throughout sexual intercourse and also ejaculation, they space expelled right into the vas deferens. The vas deferens pushes the sperm up end the bladder and down towards the prostate gland. There, the vas deferens joins the ends of the seminal vesicles (accessory reproductive glands) to kind the ejaculatory ducts. The ejaculatory ducts get seminal liquid from the vesicles, pass with the prostate, and move semen into the urethra. The masculine urethra extends indigenous the bladder, with the prostate, come the exterior orifice at the end of the penis. It receives extr seminal fluids from the prostate before it expels semen out of the body.

3. Accessory Reproductive Glands add Seminal fluid to Semen

*

Sperm cells rely on seminal fluid to store them moving and alive. This liquid is created during ejaculation by accessory glands: the seminal vesicles, the prostate, and the bulbourethral glands. The seminal vesicles, two saclike structures, sit near behind the bladder and also extend toward the bladder. Over there they each sign up with one that the vas deferens to type the ejaculatory ducts. The motor secrete a whitish-brown fluid containing sugars, prostaglandins, and other building material that provides up two-thirds that the semen volume. The prostate, situated under the bladder and over the start of the penis, includes the ejaculatory ducts and also the prostatic urethra. As semen beginning the urethra, the prostate secretes enzymes that aid activate the sperm. The bulbourethral glands (or Cowper’s glands) space pea-sized, with single ducts that attach to the urethra whereby it emerges from the prostate. These glands include mucus that helps v sperm motility.

4. Spongy internal Tissue Is key to the Reproductive role of the Penis

*

The penis is component of the male external genitalia, suspended native the human body at the front and sides of the pubic arch. Internally, the penis consists of three connected columns of tissue. The paired corpora cavernosa prolong together from the root of the prick through the body. The body spongiosum runs follow me the underside of the cavernosa. It has the spongy urethra and expands previous the body of the prick to type the glans dick (the tip). The tissue of the corpora cavernosa and the body spongiosum is spongelike in structure. During arousal and intercourse, the spaces in the tissue fill v blood. The cock stiffens. Currently it deserve to penetrate the vagina to provide semen directly into the woman reproductive system.
