The Reproductive System allows for two individuals of the opposite sex to create a new being of their own. In humans we have two different types of reproductive systems, Male and Female. The female reproductive system’s goal is to produce and care for an egg till it is ready to be born. The male reproductive system’s goal is to produce semen to fertilize the egg. When this egg grows for about 9 months, it is born into the world. Without one or the other, a baby cannot be made. The Male Reproductive system consist of various parts, including Testes, Testosterone, Epididymis, Vas deferens, Semen, Sperm, Prostate , Urethra, Penis (shaft & glanz), Seminiferous tubules, Seminal vesicles, Bladder. Below is a description of the path a sperm goes …show more content…
This is when the testes are small and there are very little tubules. When this happens there could be a great amount of infertility. There could also be degeneration of the tubules, which could also lead to the same result, infertility. Testosterone is a hormone that stimulates the production of sperm and controls the developments of male sexual characteristics. It is the LH that stimulates the release of the hormone, which is found in the testes. It helps in deepening a boy’s voice, more body hair, more muscle, and stronger bones. If there is a deficiency of testosterone, then a man could have fragile bones, decreased body hair, and decreased muscle mass. It could be caused by chronic illnesses, injury, age, or stress. Another could be too much testosterone. This could give a man less heart attacks, less likelihood of obesity, more of alcoholic side, and more likely to get injured. They have more of a risk taking side, and the cause is mainly genetics. The epididymis is a duct behind the testes that allows sperm to pass to the vas deferens. It is a long tube that lies right by the testes. Its purpose is to transport the immature sperm and allows them to mature on the way.
The testes are the primary reproductive organs in the male; they are responsible for the production of sperm. The testes are responsible for the production of testosterone, and are almost nonexistent prior to puberty. Testosterone affects vary to the sound of your voice to hair baldness. The epididymis is a firm structure that consists of three parts, sperm that passes through the epididymis after they are formed. The male urethra is approximately 18-20 cm long. The urethra allows the passage of both urine and sperm. There are two main parts of the penis; the root and body. The three main parts of the root of the penis are, the midline bulb, and the left and right crura on either side of the bulb. While the body is formed by three cylindrical masses of erectile tissue, they are the corpus spongiosum in the midline, and the two-corpus cavernosa on either side. The urethra leaves the head of the penis at the end of the corpus spongiosum.
Conception is the action of conceiving a child or of a child being conceived. Every human being begins life as a single cell, formed when father's sperm fertilizes mother's egg. Fertilization normally takes place in the mother's Fallopian tube, which connects the uterus (womb) with the ovary. The uterus is the size and shape of a large pear: it is made of muscle and it stretches to allow the baby's growth throughout the months of pregnancy.
Sperm cell is a male reproductive cell which is formed in male reproductive system. They are very tiny about 0.002 inches long, because they contain a long tail-like flagella. The main function of sperm cell is to carry the genetic information of male parent and form a new embryo when combined with an egg cell. The shape of the sperm is quite simple, like a structure of snake which comprises of a small ovular head, neck, middle piece and tail.
Testicular cancer is a type of cancer that develops in the male’s testicles first then spreads to other parts of the body. It most commonly spreads to the lymph nodes after it spreads throughout the testicles. Testicles are part of the male’s reproductive system that makes testosterone, the male hormone, and sperm. It is treatable and can usually be cured. The signs of testicular cancer are lumps, swelling, and pain in your testicles. You can check for these lumps yourself, but it is better and more important to check with your doctor for lumps annually. Testicular cancer isn’t caused by much, but there are some risks.
Infertility is the inability to conceive any children after 12 months of trying to conceive after having unprotected sex. The infertility condition can be present in both partners. The cause may be physical, including immature sexual organs, abnormalities of the reproductive system, hormonal imbalance, and dysfunction or abnormalities in other organ systems, or it may result from psychologic or emotional problems. There are treatments for men or women like drugs, assisted reproductive technology, in vitro fertilization (IVF), artificial insemination, and surgery.
A male makes one thousand new sperm per second, that is two trillion over a lifetime and they all are one of a kind, very unique. A woman has all her eggs from birth. The process starts out as meiosis, this is where 30,000 genes are then there are forty six chromosomes. Twenty three comes from your mother and twenty three come from your father, they only come together in meiosis in pairs, but they are not the same. Chromosomes make an exact copy of themselves then they condense making an X shape, chromosomes get a partner then embrace. The chromosomes cling close together in big chunks, the cell then divides pulling the pair apart with twenty three chromosomes. The cell alone is incomplete, but holds many promises. Every cell holds di...
To begin with, gender must be examined at the basic level of science in regard to physical and biological development of humans. We all understand the physical differences between the male and female gender, but how is our sex actually determined. After conception,
Cross culturally fertility and childbearing are a major concern due to the significance of passing on heritage, family names, and values to the next generation. Additionally, in many cultures the children are responsible for the care of their parents when they become elderly. Infertility is a universal concern in both Western and developing countries. It is estimated that up to 168 million people across the globe are affected with infertility. The bulk of these cases reside within developing countries (Vayena & Rowe, 2002). When couples are having trouble conceiving a child it is a source of distress for both partners (Helman, 2007, p. 176). This distress can be manifested in a variety of ways that adversely affect the family structure.
Social reproduction is the reproduction of cultural, human, and social capital in society. Therefore languages, traditions, cultural values, education, food security, and social circles are passed down from one generation to the next through Karl Mannheim’s concept of “fresh contact” and through society as a whole. Social reproduction is effective when social structures and equality within society are maintained. Inequality, poverty, and social changes that force society to adapt can impede the process of social reproduction causing what is known as a “crisis in social reproduction” (Wells, 2009). Born into Brothels demonstrates a crisis of social reproduction that negatively impacts the lives of children living in Sonagachi as a result of globalization, neoliberal policies, poverty, lack of adequate education and social structures to pass down capital, and the stigma of prostitution. Additionally, it shows the need for children to make economic contributions to their families that prevent them from leaving the brothel.
As a young adult, it may seem foolish to predict what your future family life will look like, especially in regards to children. Often times this reality is forced upon a select few, particularly homosexual couples; however, with the innovation of in vitro fertilization (IVF), a couple is met with promise and the hope of a successful family life. IVF can be described as a process by which a fetus is genetically formed in a laboratory setting. Though this process may seem unnatural in essence, it allows for a more diverse family arrangement through medical innovation. This procedure, though controversial, is seen by many as an advancement in the medical field and can be accredited to procuring a healthy child for an unfortunate family, whether
This process is called conception, the female is now officially two weeks pregnant and the fertilized egg is called a zygote. Let’s move on to pregnancy. Pregnancy is a state in which a woman carries a fertilized egg inside her body, it usually lasts up to 40 weeks, and it is divided into three trimesters, each lasting three months. The first month. The embryo is about a third of an inch long. The head, trunk, and the beginnings of the arms and legs have started to develop. By this month, the embryo starts to receive nutrients and releases waste through the umbilical cord and placenta. The heart also starts to beat. The second month. The heart is now pumping and the nervous system, including the brain and the spinal cord begins to develop. The fetus is 1 in 2.5cm now and has developed cartilage skeleton. The arms, legs, facial features and other major organs begin to appear. The third month. The fetus has grown up to 4 in 10cm and weighs a little more than an ounce. The major blood vessels are almost completed and the face starts to show up more. The kidneys and the 4 chambers of the heart are now complete. The fourth month. The fetus is now 4 oz of 112g and can kick and swallow. The
A couple is said to be suffering from infertility, if they have been having unprotected sex
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 female reproductive systems is made of 9 parts. The sex cell for the female reproductive system is called the egg or ovum. The egg spends it’s dormant life in the ovaries until it is released. The egg has 23 chromosomes within it. The ovaries have two goals: to create and house eggs and the release the female sex hormones, estrogen and progesterone. The fallopian tubes are what the egg travels through to reach the uterus. Fallopian tubes contain tiny hair-like structures called cilia; the cilia allows for mobility of the egg. The fallopian tube is roughly the size of 2 hairs, and is the site of where ectopic pregnancies happen. The process of the egg getting released from the ovaries through the fallopian tubes is called ovulation. Ovulation happens on the 14th day of the menstruation cycle The uterus is where the egg goes to after it travels through the fallopian tubes. The developing baby is held and nourished in the uterus. When the uterus is empty, it’s roughly the size of a fist but expands one an embryo starts to develop. The endometrium is the lining of the uterine wall. It’s used to protect the fetus. When the egg isn’t fertilized, menstruation ha...
From observing the origin of the 2-bp deletion of the ND2 gene of the mtDNA from the paternal germ line, it is thought that this mutation occurred in embryogenesis and thus paternal leakage of the mtDNA was mainly exhibited during early stages of fertilization and embryo development (Schwartz & Vissing 2002).
