Four normal Holstein bulls were surgically seminal vesiculectomized and vasectomized to determine the contribution of various parts of the genital tract to physical characteristics and chemistry of semen. Semen volume decreased after vesiculectomy and also after vesiculectomy and vasectomy. Total sper...
While a typical ejaculate from fertile men may contain up to 500 million sperm, the testes contribute 5% or less of the volume of semen. Men who have undergone a vasectomy or otherwise sterile men thus have no noticeable differences in the consistency, look, feel, or taste of their semen....
Semen was collected weekly by artificial vagina from 2 months before to 5 months after vasectomy. After sexual rest for 10 days, vasectomy was performed by the cranial midscrotal approach. In all ejaculates the volume, concentration, total sperm number, motility and morphology (normal spermatozoa,...

Checking the success of vasectomy Another reason you might need a semen analysis is to confirm the success of a vasectomy (a procedure toprevent pregnancy). It’s usually done 8 to 16 weeks after the surgery to see if you’re still making any healthy sperm. ...
4. Amino acids in normal human semen obtained before and after vasectomy were examined. The quantity of total amino acids before vasectomy was 667.6 mg/dl on the average, while it was 594.2 mg/dl after vasectomy. As to each amino acid, Methionine showed 5.1 mg/dl before vasectomy and 1.6...

participants had not had a vasectomy and had never sought infertility treatment. We controlled for several covariates known to affect ejaculate quality (e.g., abstinence duration before providing an ejaculate) and found no statistically significant relationships between ...
