Article Synopsis
- Capacitation in sperm involves tyrosine phosphorylation (TP), a key marker, but lifestyle factors like obesity and smoking affect semen quality without a clear understanding of their mechanisms on TP.
- A study analyzed TP levels in sperm from 40 donors and found that being overweight or smoking did not significantly change the percentage of sperm showing TP, but did relate to higher basal TP levels and increases after incubation.
- Additionally, while cryopreservation slightly raised TP levels after capacitation, most thawed samples showed increased TP levels, indicating that lifestyle and cryopreservation impact TP dynamics during sperm capacitation.
The aim of this study was to evaluate the possible beneficial effects of diet supplementation with a highly concentrated and purified docosahexaenoic acid (DHA) formula on human sperm function. We performed a prospective, randomized, double blind, placebo-controlled intervention study. One-hundred eighty human semen samples from sixty infertile patients recruited in a private assisted reproduction center were included.

Six different genotypes were found, including 21, 27, 3, 9, 3, and 4 strains. The probable source of bacteremia, according to clinical and/or microbiological criteria, was known in 42 patients (63%): respiratory tract (n = 19), surgical sites (n = 12), intravascular catheters (n = 5), burns (n = 3), and urinary tract (n = 3).
