Vasectomy is considered a simple, safe, effective and economical method used worldwide for long-term male contraception (Yang et al., 2021). The procedure involves isolation/exposition and occlusion of the vas deferens (Labrecque, 2019). That is, microsurgery is performed to cut the the duct which conveys sperm from the testicle to the urethra.
Getting "The Snip" is considered to be 99.9% effective at preventing pregnancy and, while vasectomy can be reversed in most men seeking to restore their fertility (Ramasamy & Shlegel, 2011), the surgery is usually promoted as permanent (Patel & Nguyen, 2019).
Only about 2-4% of men around the world use this method of contraception (Shattuck et al., 2016). And, approximately 3-6% of men opt for a vasectomy reversal, however this is a much more technically challenging procedure (Patel & Smith, 2016).
As such, in Australia, the Australian Medical Association advises that a vasectomy should cost around $650 while a vasovasectomy, or vasectomy reversal, should cost around $7000. Depending on the technique used to reconnect the vas deferens cut during a vasectomy, the reversal can have a success rate between 70-90% (Kavoussi, 2015).
According to Zhao et al. (2018), vasectomy has no long-term effect on testosterone and does not increase the chance of prostate cancer. Having worked with several men who've had a vasectomy, I have observed that it also does not diminish their capacity to circulate sexual energy or use their ejaculation for manifestation.
After vasectomy, many men start to produce antisperm antibodies (Nowroozi et al., 2007). This happens because the surgery may break the blood-testis barrier and sperm may come in contact with blood, setting off an immune response that attacks the "foreign" sperm. Sperm antibodies can interfere with the ability of sperm to swim and to attach to eggs thereby preventing conception even if a vasectomy reversal is successfully (Lee et al., 2009).
Therefore, you may want to consider freezing your sperm before vasectomy. This'll probably cost you AUD$600 to freeze and AUD$400+ per year to store. Making an informed decision about your vasectomy is important.
