Summary: The Male Reproductive System

Decent Essays
The male reproductive system , as stated previously, is different from the female reproductive system. The male reproductive system consists of testes, ducts, accessory sex glands, the penis, and scrotum (McLafferty, 2012 p1).
The testes consist of glandular tissue and each testis is contained in a white fibrous capsule called the tunica albuginea (McLafferty 2012 p1). The testes are held in the scrotum which is a loose sac of skin and smooth muscle. Approximately two months before birth, the testes descend from the abdominal cavity into the scrotal sac (McLafferty 2012,p1). It is critical that the testes are outside of the body before birth because the temperature of the testes is crucial to the survival of the sperm so the temperature of the testes needs to be lower than the temperature of the core body temperature ( McLafferty, 2012,p1.). If the temperature outside is too cold, the scrotal sac contracts to draw the testes close to the body allowing the body to reduce the heat lost (McLafferty 2012,p1-2). If the temperature outside is too warm, the testes descend so the cool air can circulate to lower the temperature (McLafferty,

The epididymis lies along the top and behind each testis inside the scrotum (McLafferty, 2012 p3.). The sperm travels from the seminiferous tubules to the epididymis where the sperm matures (McLafferty, 2012 p3.). The sperm travels along this duct to the vas deferens which is another temporary storage place for the sperm. On each side of the prostate gland is an ejaculatory duct. The ejaculatory duct is approximately two centimeter in length and is made when the seminal vesicle’s duct merges with the vas deferens. Semen flows through each ejaculatory duct during ejaculation eventually exiting through the penis. The urethra is contained with in the penis and provides and exit for both semen and urine

    Penis= the penis is the male sex organ containing erectile tissue that is encased in the skin. This organ delivers semen into the female vagina. Vas deferens= each vas deferens carries sperm from the epididymis up into the pelvic cavity. They travel up in front of the urinary bladder, over the top, and the back down the posterior side of the bladder to empty into the urethra. Seminal vesicles= the two seminal vesicles are small glands located at the base of the urinary bladder.…

    Gametes typically come in male (sperm) and female (eggs). In human , the process involves two specialized cell divisions. The purpose is to create a haploid cell able to be well-suited with another haploid cell. Sperms is formed by the process called spermatogenesis and eggs are formed by the process is called spermatogenesis and oogenesis respectively, details of these processes is given below Spermatocytogenesis Spermatocytogenesis is the formation of spermato- cytes and takes…

    The oviducts (uterine tubes) are a tube that extends from the uterus to the ovaries that transports eggs to the uterus. It is the location of fertilization. Implantation is where the embryo embeds in the uterine lining. The uterus is a thick-walled, muscular organ located in the pelvis (female). It is about the size of a pear and lies above and is tipped over the urinary bladder.…

    The male and female reproductive systems are distinct from one another in that the male reproductive system includes mostly external organs, produces testosterone, and produce sperm during puberty, while the female reproductive system includes mostly internal organs, produces progesterone and estrogen, and produces a set number of eggs in the womb during embryonic development. The reproductive systems, however, share one common similarity in which both systems have gonads that produce gametes and other sex organs. The first difference between the male and female reproductive systems is that the male reproductive system includes mostly external organs, while the female reproductive system includes mostly internal organs. In males, the external organs include the penis, scrotum and the testicles. The penis is made up…

    The ureters are approximately 10 to 12 inches long running on the left and right sides of the body and parallel to the vertebral column (Tomić et al, 2015). In the walls of the ureters smooth muscle contractions known as peristalsis and the influence of gravity causes urine to move to the urinary bladder. The ureters extend slightly at their ends into the urinary bladder through vesical ureter valves that prevent flowing back of urine to the kidneys. Urinary bladder. The urinary bladder resembles a sac-like hollow organ.…

    DISCUSSION Spermatozoa and its Arrival to the Egg Before embarking in the complexity of CatSper channels, the particular characteristics of sperm and its movement towards the egg in female that allows for fertilization should be addressed. Spermatozoa are differentiated motile cells that have two main structures: the head, which houses packed DNA, and the flagellum, the motility portion that transports the sperm genetic information to the egg (1). Within the spermatozoa head both a vesicle which covers the head, known as the acrosome, and the nucleus reside; whereas the flagellum (tail) is divided by the principal and end piece (4). It is in this principal flagellum piece that we can localize the CatSper channels (2,4,5). Moreover, between…
