This then opens into the urethra, i beg your pardon is the tube that takes the sperm exterior the body.
The accessory sex glands. There space three glands which create fluids that mix through the sperm to comprise semen. Semen is the fluid which is ejected from the penis during ejaculation.

That is normally about the size of a chestnut.The bulbourethral glands
The penis. The penis has a single tube in it called the urethra. There room three main parts the the penis - the root, body and also glans.

These hormones are called luteinising hormone (LH) and also follicle-stimulating hormone (FSH). LH in the bloodstream causes cells in the testicles (testes) to make and release testosterone, the key male hormone.
FSH and also testosterone job-related together to wake up the testes to produce sperm. Every sperm cabinet takes between 65-75 days to form and approximately 300 million are created every day. Inside the testes sperm is make in structures called the seminiferous tubules. At the top and to the back of every testicle (testis) is the epididymis, which shop sperm.
Leading native the epididymis is the vas deferens. The vas deferens tote sperm in the direction of the penis. Along the method it joins various other tubes and during ejaculation collection fluids indigenous the accessory sex glands. The mixture that sperm and fluids indigenous the accessory sex glands is referred to as semen. About two thirds that the volume the semen come indigenous the seminal vesicles. The semen is climate passed right into the urethra.
When sexually aroused, a number of changes occur inside the penis. The arteries giving the prick get bigger, allowing much more blood to go into its tissues.
