In a case study on sperm granuloma and antisperm antibody count in donkeys, it was found that sperm granuloma resulted in an increase in IgA- and IgG- bound sperm in donkeys. They also found donkeys with sperm granuloma had a reduction of sperm motility and reduction of percentage of sperm with an intact plasma membrane. But there was no significant damage found in total sperm motility compared to healthy control donkeys. The extent to which sperm granuloma and antisperm antibodies affect donkey fertility is still yet to be determined by further research studies. Vasectomy
Vasectomy (a birth control for males that cuts the sperm supply to semen) is usually a safe and effective contraception method. It has less than 1% failure rate and more than 95% success rate. Best candidates for vasectomy are older than 30 years individuals assigned male at birth who are in a stable relationship. Vasectomy is best performed when using the no-scalpel method to reduce operative complications. Needles also can be avoided by using a jet injector instead for the local anesthesia, which also reduces the pain that results from needles. Complications of vasectomy depends on the methods and tools used. Complications include short-term complications, such as Infection and bleeding, or long-term complications, such as sperm granuloma and post-vasectomy pain syndrome.
Additionally, in order to check sterility post-vasectomy, a semen analysis is performed after 3 months and 20 ejaculations to establish azoospermia (no sperm count in the ejaculate).Vasectomy can also be reversed, which is a more technically challenging procedure than a vasectomy that is performed by less urologists and is a heavier financial burden as it is usually not covered by insurances. Approximately 3-6% of people opt for a reversal due to the death of a child, change in partner, increase in financial abilities, or to find relief from postvasectomy pain syndrome. With advances in medical operations since the 1970s, there has since been increased interest in vasectomy reversals and greater chances of success for patency and pregnancy rates.Vasectomy reversal has a varying success rate. A recent study showed that the most important indicator of pregnancy after vasectomy reversal was the age of the female partner. The two most favorable predictors of success were having a female partner less than 40 years of age and having the reversal performed less than 15 years after vasectomy. Aside from the variation in success, vasectomy reversal also has major economic implications. The cost of a vasectomy reversal can range from $16,000-$30,000 and it is usually an out-of-pocket expense due to lack of insurance coverage. == References ==
