The Severe Acute Respiratory Syndrome (SARS-CoV-2) is present in the semen of some patients with COVID-19, including recovering patients, according to a study published online on the JAMA Network Open.
Diangeng Li, PhD, from the Chinese People's Liberation Army General Hospital in Beijing, and his colleagues examined all male patients with confirmed COVID-19 between January 26 and February 16, 2020, at Shangqiu Municipal Hospital. Thirty-eight registered patients were asked to give a sperm sample for testing SARS-CoV-2.
Of the 38 participants, 23 had succeeded clinical recovery and 15 were at acute stage of infection. The researchers found that 6 patients (15.8%) had positive results for SARS-CoV-2, including 4 who were in the acute stage of infection and 2 who recovered (26.7 and 8.7%, respectively). Patients with negative and positive test results did not differ in age, the history of urogenital diseases,the days of hospitalization or days after clinical recovery.
THE spermatogenesis still occurs in men with testicular cancer
THE spermatogenesis occurs in most men with testicular cancer, often away from tumors, according to a study published online at BJU International.
Jemma A. Moody, of King's College London, and her colleagues looked back 103 testicular stem cell tumors (TGCTs) in men who underwent radical orchidectomy (between 2011 and 2015) in order to estimate its frequency and prognostic factors spermatogenesis.
The researchers found that spermatogenesis was present in the patients' 70%. THE spermatogenesis was widespread in the 63% of these patients and focal in the 38%. His type volume, the stage, the presence micro-determination and tumor markers did not predict spermatogenesis. Spermatogenesis was 82% less likely in men with a percentage of possession testicular volume> 50% in their testes versus those with a testicular volume holding rate <50%.
"These findings can help predict and guide of successful sperm retrieval surgery in testes with TGCT", Write the researchers. "The finding of the focal point spermatogenesis in a third of patients will support a mmicrosurgical approach to sperm retrieval at the time of orchiectomy to maximize success. ”
