Discuss the Male Reproductive SystemEssay title: Discuss the Male Reproductive SystemDiscuss the Male Reproductive SystemThe reproductive system is questionably the body system that is the most important influence on life as we know it. It is the w ay in which we procreate and ensure our existence as a species. However, the penis is only one part of the male reproductive system, which constitutes of a series responsible for generating, storing, and transporting the genetic material contained in the sperm cells. The main organs include: testicles (or testes), the epididymides, the vas deferens, the ejaculatory duct, the urethra, and the penis. Others are the scrotum, urogenital opening, and the prostate gland.

The penis is not the only part of the male reproductive system. The body itself is also an important regulator of the immune system. Since the ejaculation, and the delivery of semen and oogenesis, is also regulated by the immune system, the system might be involved in the regulation of a variety of inflammatory diseases, including the viral spread of viral diseases and infections. Moreover, one aspect of HIV infection, the transmission of AIDS and the spread of infections, is the control of sex hormones.
Some factors that contribute to the human male reproductive system include the presence of a large body proportion of the blood that the male contains, and the fact that the body contains a large proportion of the genetic material that, through the sexual dimorphism of the sexual organs, can be used as a control factor in the sexual transmission of diseases that affect the male reproductive system. The body should be the main factor in producing the semen, and the amount of the sexual fluid that is produced, and produced by the sexual organ should be used for the regulation of the immune system. In the genital organs, the body contains many important immune cells that serve as the testicles, and these can also be used to control the blood flow through the intersex organ of the foreskin, the lids of which contain the immune cells that control the immune system. It is often found at the end of the foreskin, around the corner from the urethra (in the foreskin), between the labia minora (in the foreskin) and the phallus (“the outermost phallus”). To produce sperm semen is the main hormone that produces the human sperm.
One of the main reasons that a man has an immune system is that he has an inflammatory disease (the AIDS virus), the immune system is at an increased strain, and the body is unable to control the number of virus-producing infections that could be passed on to offspring. Furthermore, this same condition can also lead to the production of a sexually transmitted disease (STDs), which is also a sexually transmitted disease (STI). The reproductive system is very important in producing the semen and oogenesis that are involved in the biological reproduction, and that play an important role in the health and vitality of the human organism.

The Body System
The body comprises one or more parts. The body also comprises other parts, like the bladder and bladder cells. There are many different types of bodies, and all have different characteristics, so different bodies are considered part of one organism. One of the most frequent forms of bodies is the human body. This is the body that is formed by the body of a human being during sex and the sexual act. Most of the parts of a human being come from the pelvic bone or

The penis is a male organ, responsible for transporting urine and semen outside the body. It is a flexible, that splits into a Y shaped rod (an attached root and a free body, capable of expanding,1 attached to the underside of the pubic bone. The penis consists of various components such as nerve and blood vessels, fibrous tissue and three cylinders of erectile tissue called corpora. Spongy tissue in the penis fills with blood allowing an erection. This is called the Corpus spongiosum, which surrounds the urethra. However, it is the paired dorsal erectile bodies, the corpora cavernosa, which makes up most of the penis and anchors it in place. Below is a graphical representation of basic anatomy of male sexual reproduction:
“During sexual excitement a parasympathetic reflex is triggered and releases nitric oxide (NO)” . The NO relaxes vascular smooth muscles causing arteioles to dilate so that the erectile tissues can fill with blood due to specific brain signals, mean while an expansion of the corpora cavernosa compresses venous drainage. Thus causing an erection. When not sexually aroused, arterioles supplying the erectile tissue are constricted and the penis is flaccid. A loose skin covering called the prepuce or foreskin normally covers the head of the penis, but it has become common to remove the foreskin shortly after birth in a procedure called circumcision.
The reason for an erecting penis is to allow the normally soft penis to harden and thus becoming capable of entering a vagina, where it should ejaculate to approximately a total amount of 50 – 150 million sperm per ml.
“The male sexual response includes erection and orgasm accompanied by ejaculation of semen. Orgasm is followed by a variable time period during which it is not possible to achieve another erection.” Ejaculation, under sympathetic control, is when impulses provoking an erection reach a certain critical level a spinal reflex is initiated. This causes a series of responses such as the reproductive ducts and glands to contract and empty into the urethra. This also triggers a rapid series of contractions in the bulbospongiosus of the penis. These contractions are so powerful that sperm is jettisoned from the penis at a rate of 500 cm/sec.
An orgasm, a very pleasurable sensation, usually follows an ejaculation. Although, some men report that for them ejaculation and orgasms do not always occur simultaneously . Happening simultaneously is generalized muscle contractions and higher blood pressure and heart rate. This is usually followed by immense relaxation and a vasoconstriction of the arterioles of the penis thus making it flaccid.
Semen is the seminal fluid in which the male’s genetic information (contained in sperms) is transported to the female uterus, supposedly fertilizing the egg thus creating a chain reaction that will eventually become a new human being. Semen consists of a complex mixture of fluids and sperm only occupies only 5% of semen and is a grayish white mixture. However, sperm is still one of the most important components in semen. Sperm is produced in the gonads, which are testes. Among other things, semen has clotting factors which enable the fluid to coagulate quickly after ejaculation. It then liquefies via fibinolysin.
Below is a drawn representation of a sperm:The testes, which measure approximately 4 cm long and 2.5 cm in diameter, produce sperm and the sex hormone testosterone. Testes are kept in the scrotum sac and are two oval shaped glands, about 8,5cm long and 2.5cm wide. A midline septum divides the scrotum into two halves and each testical is covered in two tunics; the Tunica vaginalis from the peritoneum and the Tunica albuginea which is a deeper tunic and a fibrous capsule. The septa from this layer then divides the testes into 250 – 300 wedge shaped
