Vasectomy
Vasectomy is an elective surgical procedure that results in male sterilization, often as a means of permanent contraception. During the procedure, the male vasa deferentia are cut and tied or sealed so as to prevent sperm from entering into the urethra and thereby prevent fertilization of a female through sexual intercourse. Vasectomies are usually performed in a physician's office, medical clinic, or, when performed on a non-human animal, in a veterinary clinic. Hospitalization is not normally required as the procedure is not complicated, the incisions are small, and the necessary equipment routine. There are several methods by which a surgeon might complete a vasectomy procedure, all of which occlude (i.e., "seal") at least one side of each vas deferens. To help reduce anxiety and increase patient comfort, those who have an aversion to needles may consider a "''no-needle''" application of anesthesia while the ' no-scalpel' or 'open-ended' techniques help to accelerate r ...

Sterilisation (medicine)
Sterilization ( also spelled sterilisation) is any of several medical methods of permanent birth control that intentionally leaves a person unable to reproduce. Sterilization methods include both surgical and non-surgical options for both males and females. Sterilization procedures are intended to be permanent; reversal is generally difficult. There are multiple ways of having sterilization done, but the two that are used most frequently are tubal ligation for women and vasectomy for men. There are many different ways tubal sterilization can be accomplished. It is extremely effective, and in the United States, surgical complications are low. With that being said, tubal sterilization is still a method that involves surgery, so there is still a danger. Women who choose tubal sterilization may have a higher risk of serious side effects, more than a man has with vasectomies. Pregnancies after tubal sterilization can still occur, even many years after the procedure. It is not very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Post-vasectomy Pain Syndrome
Post-vasectomy pain syndrome (PVPS) is a chronic and sometimes debilitating genital pain condition that may develop immediately or several years after vasectomy. Because this condition is a syndrome, there is no single treatment method, therefore efforts focus on mitigating/relieving the individual patient's specific pain. When pain in the epididymides is the primary symptom, post-vasectomy pain syndrome is often described as congestive epididymitis. Incidence In their Vasectomy Guideline (2015), the American Urological Association stated: An investigation of peer-reviewed articles published in March 2020 examined 559 articles, performed meta-analysis on 25 separate datasets, and concluded that the incidence of post-vasectomy pain syndrome is 5% (95% CI 3% to 8%) with similar incidence of PVPS for both the scalpel and the no-scalpel technique. Symptoms * Persistent pain in the genitalia and/or genital area(s) * Groin pain upon physical exertion * Pain when achieving an erectio ...

Vasectomy Reversal
Vasectomy reversal is a term used for surgical procedures that reconnect the male reproductive tract after interruption by a vasectomy. Two procedures are possible at the time of vasectomy reversal: vasovasostomy (vas deferens to vas deferens connection) and vasoepididymostomy (epididymis to vas deferens connection). Although vasectomy is considered a permanent form of contraception, advances in microsurgery have improved the success of vasectomy reversal procedures. The procedures remain technically demanding and may not restore the pre-vasectomy condition. Procedure Preparation A general or regional anesthetic is most commonly used, as this offers the least interruption by patient movement for microsurgery. Local anesthesia, with or without sedation, can also be used. The procedure is generally done on a “come and go” basis. The actual operating time can range from 1–4 hours, depending on the anatomical complexity, skill of the surgeon and the kind of procedure perform ...

No-scalpel Vasectomy
No-scalpel vasectomy (also called non-scalpel vasectomy, keyhole vasectomy or NSV) is a type of vasectomy procedure in which a specifically designed ringed clamp and dissecting hemostat is used to puncture the scrotum to access the vas deferens. This is different from a conventional or incisional vasectomy where the scrotal opening is made with a scalpel. The NSV approach offers several benefits, including lower risk for bleeding, bruising, infection, and pain. The NSV approach also has a shorter procedure time than the conventional scalpel incision technique. Both approaches to vasectomy are equally effective. Because of the inherent simplicity of the procedure it affords itself to be used in public health programs worldwide. This method is used in over 40 countries for male sterilisation. History No-scalpel vasectomy was developed and first performed in China by Dr. Li Shunqiang with the aim of reducing men's fear related to the incision and increasing vasectomy use in China. I ...

Sperm Granuloma
A sperm granuloma is a lump of leaked sperm that appears along the vasa deferentia or epididymides in vasectomized individuals. While the majority of sperm granulomas are present along the vas deferens, the rest of them form at the epididymis. Sperm granulomas range in size, from one millimeter to one centimeter. They consist of a central mass of degenerating sperm surrounded by tissue containing blood vessels and immune system cells. Sperm granulomas may also have a yellow, white, or cream colored center when cut open. While some sperm granulomas can be painful, most of them are painless and asymptomatic. Sperm granulomas can appear as a result of surgery (such as a vasectomy), trauma, or an infection (such as sexually transmitted diseases). They can appear as early as four days after surgery and fully formed ones can appear as late as 208 days later. Sperm granulomas are a common complication of different types of vasectomy. In vasectomies, the vas deferens are cut and the two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compulsory Sterilization
Compulsory sterilization, also known as forced or coerced sterilization, refers to any government-mandated program to involuntarily sterilize a specific group of people. Sterilization removes a person's capacity to reproduce, and is usually done by surgical or chemical means. Purported justifications for compulsory sterilization have included population control, eugenics, limiting the spread of HIV, and ethnic genocide. Forced sterilization can also occur as a form of racial discrimination. While not always mandated by law (de jure), there are cases where forced sterilization has occurred in practice ( de facto). This distinction highlights the difference between official policies and actual implementation, where coerced sterilization take place even without explicit legal authorization. Several countries implemented sterilization programs in the early 20th century. Although such programs have been made illegal in much of the world, instances of forced or coerced s ...

Contraception
Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using human birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable. The World Health Organization and United States Centers for Disease Control and Prevention provide guidance on the safety of birth control methods among women with specific medical conditions. The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and contraceptive implant, implantable birth control. This is followed by a number of hormonal contraceptive, hormone-based methods includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasitis Nodosa
Vasitis nodosa is a complication experienced in approximately 66% of men who undergo vasectomy.

Vas Deferens
The vas deferens (: vasa deferentia), ductus deferens (: ductūs deferentes), or sperm duct is part of the male reproductive system of many vertebrates. In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens. The vas deferens ends with an opening into the ejaculatory duct at a point where the duct of the seminal vesicle also joins the ejaculatory duct. The vas deferens is a partially coiled tube which exits the abdominal cavity through the inguinal canal. Etymology ''Vas deferens'' is Latin, meaning "carrying-away vessel" while ''ductus deferens'', also Latin, means "carrying-away duct". Structure The human vas deferens measures 30–35 cm in length, and 2–3 mm in diameter. It is continuous proximally with the tail of the epididymis, and exhibits a tortuous, convoluted initial/proximal section (which measures 2–3 cm in length). Distally, it forms a dilated ...

Antisperm Antibodies
Antisperm antibodies (ASA) are antibodies produced against sperm antigens. Types Antisperm antibodies are immunoglobulins of IgG, IgA, and/or IgM, which are directed against sperm antigens. ASA can be detected in ejaculate, cervical mucus, follicular fluid, and blood serum of both males and females. While IgG and IgA might be present in blood serum and/or genital tract fluids, IgM is only present in blood serum. IgG occurring in genital tract fluids is either produced locally or transuded from blood serum, whereas IgA (secretory type) is always produced locally. Causes Traditionally, the breakdown of the blood-testis barrier had been established as the cause of ASA production. This mechanism had been advocated in testicular trauma and surgery, orchitis (mumps), varicocele, bacterial infections (epididymitis, prostatitis), testicular cancer, and unprotected anal intercourse. However, the association between aforementioned conditions and ASA production is controversial. Onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrophage
Macrophages (; abbreviated MPhi, φ, MΦ or MP) are a type of white blood cell of the innate immune system that engulf and digest pathogens, such as cancer cells, microbes, cellular debris and foreign substances, which do not have proteins that are specific to healthy body cells on their surface. This self-protection method can be contrasted with that employed by Natural killer cell, Natural Killer cells. This process of engulfment and digestion is called phagocytosis; it acts to defend the host against infection and injury. Macrophages are found in essentially all tissues, where they patrol for potential pathogens by amoeboid movement. They take various forms (with various names) throughout the body (e.g., histiocytes, Kupffer cells, alveolar macrophages, microglia, and others), but all are part of the mononuclear phagocyte system. Besides phagocytosis, they play a critical role in nonspecific defense (innate immunity) and also help initiate specific defense mechanisms (adapti ...
