Male reproductive system

For men, the external reproductive organs include: • Penis: This tubular, muscular organ fills with blood during arousal, thus making sexual intercourse possible. • Scrotum: This pouch-like sac hangs below the penis and encases the testes, or testicles. • Testicles: These two oval shaped organs produce sperm cells and testosterone. While all men are born with all of their sexual organs, they don’t begin to function fully until puberty. The average age of puberty for males is around 12. During this time, hormone changes affect a boy’s gonads and create lasting changes that have typically been viewed through history as “when a boy becomes a man.” This process has many effects, such as growth in stature, muscular development, and hair growth on the genitals and face. In terms of reproduction, puberty signals the time when a man has fully-functioning sexual organs and is capable of fathering an offspring. The male testes produce spermatozoa (more commonly referred to as sperm), which are released at sexual climax, or orgasm. This is known as ejaculation. The sperm leaves the penis in a mixture of secretions designed to nourish and transport the cells into the female reproductive system for procreation. There are up to 750 million sperm cells contained in a single ejaculation, but it only takes one sperm cell to fertilize a woman’s egg. The testes also produce the hormone testosterone, which is directly absorbed into the bloodstream. Along with regulating sperm production and m...

Overview Male hypogonadism is a condition in which the body doesn't produce enough of the hormone that plays a key role in masculine growth and development during puberty (testosterone) or enough sperm or both. You can be born with male hypogonadism, or it can develop later in life, often from injury or infection. The effects — and what you can do about them — depend on the cause and at what point in your life male hypogonadism occurs. Some types of male hypogonadism can be treated with testosterone replacement therapy. Male reproductive system The male reproductive system makes, stores and moves sperm. Testicles produce sperm. Fluid from the seminal vesicles and prostate gland combine with sperm to make semen. The penis ejaculates semen during sexual intercourse. Hypogonadism can begin during fetal development, before puberty or during adulthood. Signs and symptoms depend on when the condition develops. Fetal development If the body doesn't produce enough testosterone during fetal development, the result may be impaired growth of the external sex organs. Depending on when hypogonadism develops and how much testosterone is present, a child who is genetically male may be born with: • Female genitals • Genitals that are neither clearly male nor clearly female (ambiguous genitals) • Underdeveloped male genitals Puberty Male hypogonadism can delay puberty or cause incomplete or lack of normal development. It can hamper: • Development of muscle mass • Voice deepening • Growth o...

A vertical septum divides the scrotum into left and right compartments, each of which encloses a testis. The external scrotum positions the testes outside the body in an environment about 3°C below that of the body cavity, a condition necessary for the development and st...

The male reproductive system refers to the bodily systems responsible for sexual function in males. It consists of external and internal structures responsible for the formation, storage, and ejaculation of sperm, as well as the production of vital hormones for male development. Similar to the female reproductive system, the male counterpart consists of various organs whose primary function is to accomplish reproduction. In this article, we will explore the various components of the male reproductive system, including their individual functions. Sex and gender exist on spectrums. For the purposes of this article, we use “male” and “female” to refer to a person’s sex assigned at birth. The organs that comprise the male reproductive system all have individual roles that in combination aid in reproduction. To facilitate reproduction, the male reproductive system has several functions within the body. These • the production and secretion of male sex hormones • the production of sperm and semen • the transportation of semen into the female reproductive tract The male reproductive system comprises external and internal organs. The external organs • penis • testes • scrotum • epididymis The penis The The erectile tissue The penis has a root, a body, and a glans penis. The body is the visible cylindrical portion, while the root attaches to the pubic arch of the pelvis. The The function of the penis, in addition to aiding in urination, is to assist with reproduction by transporting...
