Vas deferens Essays

This is where the Doctor’s would feel for the vas deferens. Put forceps to hold the vas deferens while the Doctor’s would poke a hole allowing the vas deferens to be pulled out and cut and closed shut. This is all done without having to cut the scrotum skin. This procedures involves no stitching and is companied with very little bleeding. With less complication. Third is a clip vasectomy. This is where instead of the vas deferens being cut or tied they are clamped together, which later

1.Spinal cord - is a long, and tubular shaped structure that contains nervous tissue and cells located at the end of the brainstem and continues down to the bottom of the vertebral column. It used to connect the peripheral nervous system and the brain. It acts as sensory system and transmitted message to the brain. 2.Conus medullaris - is a tapered structure that located in the most distal part of the spinal cord and end with filum terminale. 3.Cauda equina - It makes of spinal nerves and spinal

*These are endocrine cells which secretes male sex hormones. B) Vasa deferentia – *A narrow and convoluted duct arise from the inner broader side of each testis called vas deferens

Whenever a couple tries to conceive, it a glorious yet intimidating part in life. Essentially, infertility is defined as the inability to give birth after 12 months following unprotected intercourse (“What is Infertility”). Studies show that male partners usually contribute 20% to the event of infertility while female partners contribute 40%-50% (Nordqvist, Christian). Some external factors of infertility include consumption of anabolic steroids, illegal drugs and smoking, which can also cause testicles

Abstract: The purpose of this review was to determine the contribution of different factors which may promote the ratio of infertility in male. Many studies have supported that different factors such as infections, smoking, alcohol, pesticides, and different environmental and nutritional factors reversibly or irreversibly influence the male fertility. Key words: Male infertility, Reactive oxygen species, Varicocele, spermatogenesis, Genetic factor, antioxidant, Infertility

This prevents the sperms from mixing with semen. The testicles continue creating sperm, however, the body reabsorbs it by testis. The vas deferens blocks the prostate and seminal vesicles. It typically takes a few months for all the remaining sperms to become reabsorbed after a vasectomy. Extra precautions of using other methods of birth control are suggested until a sample can be tested

Of all the systems of the body, the reproductive system is somewhat sui generis. In contrast to others, the reproductive system appears to be "sleeping" until puberty without significant involvement in vital body processes. When "wake up" after after more than a decade old, produces substantial changes in body anatomy and sentimental individual behavior. The primary sexual organs or gonads are the ovaries in females and testes in males, and these organs produce sex cells gametes. They also secrete

Sometimes it is hard for people to know which form of birth control is best. There are so many choices that are available. One popular form is the birth control pill which has been around for over 50 years. The pill is a hormonal contraceptive that must be taken every day which many women use to prevent pregnancy. The birth control pill is the most common used form of birth control (Smith). The hormones in the pill prevents the release of an egg from a woman’s ovaries (Holland). The birth control

Northern Pintail Research Paper Fall 2015 Jacob A. Keller South Gibson County Northern Pintail Research Paper Fall 2015 The Northern Pintail or Anas acuta as its scientific name states is a dabbling North American waterfowl. The duck is known as one of the most graceful of all the fowl in the Western Hemisphere. This paper shall dive, or rather dabble into the life sustaining habits and delicate structures of the Northern Pintail. Skeletal System. The skeletal system of the Northern Pintail has

Cystic fibrosis What is cystic fibrosis? Cystic fibrosis is genetic disorder characterized by abnormal chloride channels. This characteristically results in disease affecting multiple organ systems, most notably the lungs and gastrointestinal tract. Lung disease is usually manifested as obstructive lung disease due to bronchiectasis. Paints often develop difficulty breathing, cough, and wheezing. The pancreas is also frequently damaged in cystic fibrosis, which leads to recurrent pancreatitis

cortex, renal medulla, renal pelvis, and the renal artery. Using diagram 14, the lab groups found the testicles and leaned them of fat. They cut and opened the tunic and identified the testis, epididymis, and the vas deferens. The last step of dissection made them trace the vas deferens to the urinary bladder. As a final step to the whole lab, the lab groups then removed all dissection pins, cleaned the dissection tools, placed the Neovison vison in a

b- Vasectomy: Vasectomy involves incision of the scrotal sac, transection of the vas deferens, and occlusion of both ends by fulguration or suture ligation. The procedure is usually performed with the patient under local anesthesia in an outpatient setting. Complications include hematoma formation and sperm granulomas. Spontaneous resolution is rare. After sterilization, remnant sperm remains in the ejaculatory ducts. The man is not considered sterile until he has produced sperm-free ejaculates as

BIO 308: ANIMALS : FORMS AND FUNCTIONS TITLE Abstract Introduction Octopuses are one of the smartest animals in the world. Octopuses live in oceans all over the world including pelagic waters ( near water's surface near the shells), coral reefs and crevices. Anatomy Octopuses are non skeletal organisms which are able to move around the water with speed and grace. They are able to fit into the space which is much smaller than their body size. Adult octopuses usually weigh 15 kgms and

Male infertility What is Male infertility? Male infertility can be defined as a male 's inability to cause pregnancy in a fertile female. A man’s fertility normally depends on the quantity and quality of his sperm. In case if the number of sperm a man ejaculates is quite low or if the quality of sperm is poor, it would be difficult, and even in some cases is impossible, for him to cause a pregnancy in a female. There are number of factors associated with male infertility such as low production of

Three differential diagnoses for scrotal pain Scrotal pain is also referred to as testicle pain or testicular pain and it occurs when pain is felt in or around one or both testicles. Epididymitis: Inflammation of the Epididymis Epididymitis is an inflammation of the epididymis, a curved structure at the back of the testicle in which sperm matures and is stored (Uphold & Graham, 2013). When the pain occurs as an acute condition, the symptoms can last up to six weeks (Uphold & Graham, 2013). This

differences, the organs that are remotely the same in both pigs and humans include, stomach, spleen, bile duct system, small intestines, kidneys, bladder, pericardium, vena cava, esophagus, phrenic nerve, urethra, ovaries, labia, testes, epididymis, vas deferens,

Kallmann’s Syndrome : A Rare Case Report ABSTRACT : Background : KALLMANN SYNDRME (kal S), a Developmental Hypothalamic Dysfunction, resulting from defective Hypothalamic Gonadotropin-releasing Hormone (GnRH) synthesis and is seen in association with Hyposmia or Anosmia ( a deficiency of sense of smell ) due to olfactory bulb/tract hypoplasia or agenesis. Clinical Features of the syndrome are attributed to GnRH deficiency as well as underlying genetic defect. It is not unusual for congenital causes

With some ideas of the castration here are three methods for physical castration nowadays which are 1surgical castration, 2Burdizzo castration and 3banding and Cutting. Surgical castration need to remove the vas deferens. Burdizzo castration named from a surgeon Napoleone Burdizzo, using a clamp also carries his name in the surgery procedure which is a pair of pincers with a strong compound leverage action. The surgery required this clamp to crush the spermatic

considered this a technically demanding surgery and the results were not quite as good in other people's hands [9]. Swenson's operation may be associated with injury of deep pelvic nerves, vessels and other structures such as vagina, prostate, vas deferens and seminal vesicles if dissection is not intimately done on the rectal wall [10]. To avoid such complications, many procedures were developed. Duhamel performed a retro rectal trans-anal pull-through to treat Hirschsprung’s disease [2]. This concept

Testicular Cancer Research Project Testicular cancer is when there is an abnormal growth in the testicals from malignant cells. Cancer in the testicals is very rare since it is not primarily hereditary, and it is very curable when found in its early stages (WebMD,2015). It is mostly only caused by germ cells (sperm cells) that have mutated in such a way that it causes cancer (WebMD,2015). With testicular cancer there is a .38% percent chance that males in the United States will get testicular cancer
