The Reproductive System Its Functions And Disorders.
The reproductive system is the part of the human body that is necessary to continue the human existent. Reproduction in humans normally would begin by a male and female having sexual intercourse with each other.
Men and women are both unique in the way their bodies and are formed and developed. Men and women both go through the most changes during their adolescent years when they begin going through puberty. Puberty normally begin in a male from the age of 11 and continues through the age of 16. Boys will develop a deeper voice; growth of hair on their face and body, a boy will have spurts of muscle growth, their testes will begin to produce sperm. A teenage boy will start producing a hormone called testosterone that is produced by their testes. Male’s reproductive system primary genitalia are their testes.
The human male reproductive system organs are located outside of the body around the pelvic region of a male (wikipedia, 2010). The testes produce sperm that would fertilize the female’s egg. Males have several secondary genitalia’s the penis, sperm ducts, epididymis, vas deferens and the urethra. The urethra is used for two purposes to urine and to ejaculate semen. Males also have accessory glands such as the prostate gland, seminal vesicles, and bulbourethral glands. The prostate gland contributes fluid for ejaculation. Prostate fluids helps to nourish the sperm (Web Md, 2009). The seminal vesicle makes up most of the volume of a man's ejaculatory fluid and provide the sperm with nutrients that give the sperm energy(Web Md, 2009). Bulbourethral glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra ...

The testes produce sperm and sex hormones, testosterone. Surrounding each testis is a coiled tube called the epididymis, which collects and stores sperm, very much similar to that of a human. Before ejaculation a seminal fluid is added by the seminal vesicles, to prevent the sperm from drying out.
The teenage year is the time when the body starts producing sex hormones and goes through a major growth spurt. This is the period when
For male cats, they have a penis, prostate, scrotum (with paired testes), which all aid in creating sperm and testosterone. Additionally, the most unique feature they have is that on their penis they have little spins and barbs that hold the penis in during ejaculation.
About half of a man’s testosterone is actually freely in circulation, or ‘biologically active’. The other half is bound to a globulin, called the sex h...
One stage of adolescent development that my teen went through was puberty. Puberty is different for girls and boys and is manifested differently as they go through many physical and cognitive changes. As I was raising my teen daughter I noticed that the changes in her body during puberty played a role in the way she viewed herself. By age 11 she became more interested in her appearance as a result of some compliments from some boys in her school. She started to wear makeup to school every day and became more interested in buying new clothes and shoes. As pu...
Puberty is defined as the beginning of sexual maturity. It is the period when a child changes physically, hormonally, sexually, and is able to reproduce. For girls, puberty begins around ages ten or eleven and ends around age sixteen. Boys enter puberty later than girls, usually around age twelve, and it lasts until around ages sixteen or seventeen (Parents & Teachers: Teen Growth & Development, Years 11 to 14). Precocious puberty means having development of breasts or testes, menstrual bleeding, pubic and underarm hair, body odor, and an increased growth rate earlier than normal. For girls, puberty is generally considered to be too early if it begins at age seven or eight. African-American and Hispanic girls tend to start puberty slightly earlier than Caucasian girls. For boys, puberty is generally considered too early before the age of nine years (Adkins, Deanna, and Dennis Clements).
Vas deferens transport the sperm to the penis . Cowper’s gland has two small glands that secrete a mucous to the male uretha . All boys are born with foreskin which is a folded skin that covers the penis . The doctor have to cut the foreskin off . When a new born baby is born that’s when they usually cut it . The male have 5 secondary characteristics which are growth , more muscular , deeper voice and body hair that’s dealing with puberty . Most males stop growing at 18 or sometimes 21 . Also hair starts to come in during puberty . The female reproductive system includes the clitoris , labia minare , and Blartholin’s glands . The clitoris is small sensitrive and erectile part of the female vulva . The inner and outer folds the uvlua . The Bartholin’s glands is the lower part of the vagina . The vagina meets to the outside at the vulva , which includes the labia , clitoris , and uterus . Also the vagina is a fibro - muscular tublar tract leading from the urterus . The ovaries are small and the place inside the female body the place inside the female body . The speed of ovulation is periodic and impacts directly to the length of mestrual cycle . The breast starts to come in during
The hormonal mechanisms that influence the male reproductive functions involve the endocrine tissues, the hypothalamus, anterior pituitary and the reproductive organ that is also considered and endocrine tissue, the testis. In the hypothalamus specific neurosecretory glands secrete GnRH, or gonadotropin releasing hormone. GnRH is carried by the blood to the anterior pituitary gland where it binds to receptors on gonadotrophic cells. The GnRH stimulates the gonadotrophic cells to increase the secretion of two gonadotrophic hormones, Luteinizing hormone (LH), Follicle - stimulating hormone (FSH). These to hormones are transported in the blood from the anterior pituitary gland to the testis. In the testes LH bind to leydig cells which in turn stimulates the secretion of testosterone. With the assistance of FSH and testosterone, stertoli cells are able to produce ABP, Androgen-bind protein maintains high levels of testosterone. ABP binds to testosterone and maintains high levels of that hormone near spermatogenic cells. This with FSH help in the maturation of spermatozoa. In addition to all this, testosterone is converted into DHT, dihydrotestosterone, this hormone may also contribute to the formation of sperm cells. The two androgens testosterone and DHT, help to develop males sexual characteristics and The process described above can be seen in figure
Adolescence is the transitional stage from childhood to adulthood, commonly occurs amongst individuals aged between 12 to 18 years (Hoffnung et al., 2016, p. 350). It is a developmental period characterised by hormonal changes that result from the onset of puberty, which is defined by the emergence of secondary sexual characteristics, such as growth of body hair and deepening voices in males, and breast development and menstruation in females (Jones & Creedy, 2012, p. 28). The timing in the onset of puberty differs in gender, girls generally reach pubertal development at an earlier age than boys (on average 13 years old for girls, and 14 years old for boys). In addition, environmental variables also influence the timing of puberty. For example,
Adolescence is a period of physical and psychological development from the onset of puberty to maturity. The adolescent is no longer a child, but they haven’t yet reached adulthood. Adolescence is considered people between the ages of 13 and 21. Puberty is the physical maturing that makes an individual capable of sexual reproduction. Puberty is important to adolescence because when a child hits puberty, that’s when the child is becoming an adolescent. Puberty is a big part of an adolescent’s life.
The male reproductive system works to create sperm and then release it into the female during sexual intercourse. The organs in the system are the testes, the epididymides, hanging in a skin bag called the scrotum, the sperm ducts, the prostate gland, and the penis containing the urethra. The testes are also known as sperm glands. They make tiny sperm cells called spermatozoa. They also produce hormones especially testosterone (this activates the production of sperm cells). Epididymides are tightly coiled tubes on each side of the testes. They help sperm become mature. The sperm ducts carry fresh sperm towards the outside. The ducts join with the urethra inside of the prostate. The urethra carries the sperm through the penis to the outside. This pathway is also known as the male reproductive tract.
The male reproductive system is a set of organs that works together to produce sperm which will later in life fertilize females eggs. The testes are the most important part of the system because it produces sperm cells. It is similar and looks similar to ovaries of a female’s reproductive system because it also holds what they need to reproduce. Its job is to produce the sperm cells needed to reproduce. Due to hormonal imbalances the production of sperm cells may not even be possible in some males. Testosterone is the male the hormone that gives men there manly characteristics. It is made up of hydrogen, carbon, and oxygen with a white color. In the male body it helps develop sex organs, a deeper voice, and facial hair (Khalid, 2013). Cancer or a genetic disorder in males is the most common thing that cause the reductions of testosterone production in the body. Behind the testes is the epididymis which lets sperm go through the vas deferens from the testes (Dictionary, 2014). It looks like leach the way it is position right on the testes but it is thinner. When sperm is produces the ...
The prostate gland is the largest accessory sex gland . it is found at the base of the bladder and it encircles the prostatic urethra. This gland secretes prostatic fluid that makes up 30% of the semen into urethra contributing to sperm motility and viability. The prostate is classified as a tubulo- alvelolar gland having two distinctive units the epithelium and stroma. The constituents of the stroma are fibroblast , Smooth muscle cells and collagen. The epithelium is mainly simple columnar secretor. In the stromal compartment there are sparse neuroendocine cells (45). The prostate epithelial cells are either classified as basal or luminal. the basal cells are characterized by set or markers mainly cytokeratin 5, 14 and p63 . However, a different set of markers are expressed by the luminal cells mainly cytokeratin 8,14,18,19 ,(46)
...urpose is to clean the urethra of harmful bacteria and other substances prior to ejaculation. The penis, not composed of muscle or bone, is the next step for the sperm. It’s three main purposes are to transport urine, transport semen, and to provide sensation. Inside the penis is the urethra. The urethra’s functions are to carry urine from the bladder to outside the body, and to ejaculate semen during sexual intercourse. The tip of the penis is called the scrotum, and it’s three main functions are to act as a thermometer for the testicles, protect and hold the testicles, and to provide various sensations.
Children grow in the body through various ways , their inner body systems change , they grow taller , get heavier , and a myriad of other things. The one defining time of growth would again be during adolescence when the sex traits and major height growth takes place. During this time there is a large growth in hair on both although most often it is more prominent on men such as through facial hair and beards but the most significant growth shared by the two would be the growth in height and changes in hormones. The latter is especially important when it comes to sexual changes during these times , women start coming to a point when they menstruate and men get to a point of sexual maturity when they begin to produce sperm. Along with these aforementioned changes in the sexes there are other changes that take place such as the dropping of the testes in males and the growth in the mammary glands in the chest for
