Essay about Discuss the Male Reproductive System

Testes: The function of the testes (following puberty) is to produce spermatozoa and androgens, mainly testosterone. The testes produce sperm; about 300 million are released with each ejaculation.

dia in EUROPE show more nudity than in the united states Chapter 2 Clitoris- a small, elongated erectile structure in women that develops from the same embryonic tissue as the penis Cowper’s Gland- two pea-shaped structures located beneath the prostate gland in men that secrete a few drops of an alkaline fluid prior to orgasm Hymen- the thin membrane that partially covers the vaginal opening in many sexually inexperienced women G Spot- a small, sensitive area on the front wall of the vagina found in about 10% of women Penis- the male organ for sexual intercourse and the passageway for sperm and urine Scrotum- the pouch beneath the penis that contains testicles Vuvla- external female genitalia, including the mons veneris, labia majora, labia minora, clitoris, vaginal opening, urethral opening

This complex organ can be found in upper right side of the abdomen. It is unique because it is a dual functioning organ. The first function is to control the body’s blood sugar level. The second function is to secrete insulin and glucagon. Lastly, I studied the testes of the fetal pig, which I found at the end of the scrotum under the skin. The teste are a key part in the process of secreting testosterone. After completing this section I began to dissect the last system of the pig.

Actually, urinary system is not an isolated organ and is composed of kidney, ureter, bladder and urethra. Kidney plays the role of filtering blood, during which blood and wastes are separated. Filtered blood flow out of kidney through renal vein and wastes flow

The penis is the male organ through which sperm cells are transferred from the male to the female. The penis contains three columns of erectile tissue. Engorgement of this erectile tissue with blood causes the penis to enlarge and become firm this process is called erection. Two of the erectile columns form the dorsum and sides of the penis and are called the corpora cavernosa. The third column, the corpus spongiosum, forms the ventral portion of the penis. It expands to form a cap over the distal end of the penis. The spongy urethra passes through the corpus spongiosum, penetrates the glans penis, and opens as the external urethral orifice. At the base of

The patient was brought to the operating room and placed on the table in a supine position. After induction of adequate general anesthesia, patient was prepped and draped in a sterile fashion. Curvilinear incision was made superior and lateral to the os pubis and carried it down through the skin and subcutaneous tissue on the right. External oblique was identified and opened in direction of the fibers. Once this was done, the spermatic cord was elevated using a Penrose drain. There was a fair amount of scarring and a large lipoma of the cord, which obstructed visualization. The lipoma was carefully dissected away from the cord and the cord structures down to the level of the internal ring and then imbricated. Once this was done, the cord was inspected no evidence of

The scale of the testicles is well correlated to the synthesis functionality of the sperm and further gonadal sperm reserves [Parkinson et al., 2004]. The scrotal circumference is the best and the most sophisticated device for estimating the mass of the reproductive organs [Lino et al., 1972; Notter et al., 1987] and the level of testes development [Lunstra et al., 1978] inside the animal. The testicle circumference and histological sections were assessed to determine the efficacy of the vaccine on gonadal features. Analysis of the sub-physiological contents of testicles revealed a direct relationship between the steroid and spermatogenic production. Our research finding shows that the vaccine has a strong effect on the scrotal circumference of immunized ram lambs compared with the control ram lambs (P < 0.05). Furthermore, the microscopic histological outcomes of testicles indicate that the vaccinated ram lambs indicated lower masses of spermatogonium, spermatocytes, and spermatids. The histological observation revealed smaller seminiferous

• Can pass back and forth between the scrotum and abdomen because the tube is still open (communicating hydrocele).

Bulbourethral glands (Cowper's gland) are located at inferior to the prostate on either side of the membranous urethra and their ducts open into the spongy urethra. During the time of sexual arousal, the bulbourethral glands release an alkaline fluid into the urethra that guides the sperm

The prostate is a walnut-sized gland that lies below the urinary bladder and surrounds the urethra. Along with the seminal vesicles, the prostate gland produces a fluid, called prostatic fluid, that contains, protects, nourishes, and supports the sperm. The white, sticky fluid originally from the prostate forms most of the volume of the semen. The prostate has no known function other than reproduction.

The prostate gland produces most of the fluid that nourishes and transports sperm. It’s located just below the bladder and surrounds the urethra, through which urine passes out of the body. After puberty, the prostate is about the size of a walnut. As men age, the gland gradually increases in size (see illustration).

Pathophysiology: According to Heather and McCance 90% percent of testicular cancers are germ cell tumors, arising from the male gametes. Germ cell tumors include seminomas, embryonal carcinomas, teratomas, and choriosarcomas. Testicular tumors also can arise from specialized cells of the gonadal stroma (Leydig, Sertoli, granulosa, theca cells) although they make up only about 10% of the total cases. Non-seminomas tend to grow at a faster rate and metastasize more quickly than seminomas.

Unlike humans and many other animals, female Emperor Penguins do not have a vagina and the males do not have a penis. The main male reproductive parts are the testis, ureter, vas deferens and cloaca. The testis grow in size during mating season to produce more sperm. The sperm then travels through the ureter and a tube called the vas deferens. This then leads to the cloaca where the sperm is stored. The cloaca is also an opening of the digestive, reproductive and urinary tract. The main female reproductive parts include the ovaries, where the eggs are produced, the oviduct which is where the egg travels through, a uterus, ureter and a cloaca which leads to the ovaries.

Conventional castration comprises separate longitudinal incision over each testis, occlusion and transection of spermatic cords and removal of testicles. The scrotal incisions are left unsutured (Stubbs, 1998; Boothe, 2003 and Tobias, 2010). Closed and open castration techniques are performed in cats. Methods to occlude the spermatic cords are; performing square knots with the spermatic cord over itself, placement of square knots of the vascular part with the avascular part of each spermatic cord, application of titanium clips over the course of spermatic cord, double ligation of spermatic cord with appropriate absorbable suture material or coagulation with bipolar forceps (Porters et al., 2014). The intra-operative obstacles are concluded in highly movable small testicles which are difficult to stabilize in scrotum, short spermatic cord and friable nature of the spermatic cord at this age (Howe, 2006 and Root 2014). Castration with ablation of scrotum had been recorded in equids (Barber, 1985; Palmer and Passmore, 1987; Misk and Seleim, 1987) and in ruminants (Misk, 1982). This technique offers primary closure of the wound, no drainage, minimal swelling and quicker return to activity (Palmer and Passmore, 1987 and Bassert, 2017). Ablation of scrotum is indicated in castrated pets showed post-operative exudate accumulation or infection (Stubbs, 1998; Boothe, 2003; Fossum, 2007 and Børstad, 2015). The aim of the

Semen is the male reproductive fluid, containing spermatozoa in suspension. Sperm is a male reproductive cell. Prostate is a gland surrounding the neck of the bladder in male mammals and releasing prostatic fluid. Urethra is a duct by which urine is convey out of the body from the bladder, and which in male vertebrates also conveys semen. Penis is the male genital organ of higher vertebrates, carrying the duct for the transfer of sperm during copulation. Glans is the head of a penis. A shaft is the cylindrical part of the penis between the scrotum and head. Seminiferous tubules is any of the numerous long convoluted tubules in the testis which are the sites where spermatozoa mature. Seminal vesicles is each of a pair of glands that open into the vas deferens near its junction with the urethra and secrete many of the components of semen. Bladder is a membranous sac in human and other animals, which urine is collected for excretion.
