A semen analysis (plural: semen analyses), also called seminogram or spermiogram, evaluates certain characteristics of a male's semen and the sperm contained therein. [1] [2] [3] It is done to help evaluate male fertility, whether for those seeking pregnancy or verifying the success of vasectomy. Depending on the measurement method, just a few ...
If sperm were seen in one or both vas contents at the time of surgery, or sperm reached the patient's semen only transiently after the reversal, microsurgical vasovasostomy may be successful. Unfortunately, surgeons performing only an occasional vasectomy reversal often neglect examining the vas contents for presence or absence of sperm.
Among 159 men identified as potentially having CUAVD, 47 had only one testicle, 26 had bilateral vasa, and four were misdiagnosed (post-vasectomy semen analysis showing motile sperm after unilateral vasectomy) leaving 82 men deemed cases of CUAVD (0.36% of total sample). 82 men were further classified as confirmed (n=48, 0.21%) and possible (n ...
In January 2008, the FDA cleared a home test called SpermCheck Vasectomy that allows patients to perform postvasectomy confirmation tests themselves; [15] however, compliance for postvasectomy semen analysis in general remains low. Late failure, i.e. pregnancy following spontaneous recanalization of the vasa deferentia, has also been documented ...
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 ...
Azoospermia is the medical condition of a man whose semen contains no sperm. [1] It is associated with male infertility, but many forms are amenable to medical treatment.In humans, azoospermia affects about 1% of the male population [2] and may be seen in up to 20% of male infertility situations in Canada.
Cauterization is a vasectomy method used to seal the vas deferens by utilizing heat or electricity to burn the lumen. Using thermal (heat) cautery instead of electrocautery can help prevent granulomas and nodular thickening. [2] Refraining from ejaculation for 1 week can potentially reduce the risk of developing a sperm granuloma. [2]
The human vas deferens measures 30–35 cm in length, and 2–3 mm in diameter. [3]: 1297 It is continuous proximally with the tail of the epididymis, [3]: 1296 and exhibits a tortuous, convoluted initial/proximal section (which measures 2–3 cm in length).
