TL;DR: Overweight and obesity were associated with an increased prevalence of azoospermia or oligozoospermia, and whether weight normalization could improve sperm parameters should be evaluated further.
Journal ArticleDOI
Male accessory gland infection and sperm parameters (review).
TL;DR: It is shown that all components involving the inflammatory response can deteriorate conventional and/or non-conventional sperm parameters arising from one or more of the following mechanisms: altered secretory function of the epididymis, seminal vesicles, and prostate which reduce the antioxidant properties or scavenging role of the seminal plasma; deterioration of spermatogenesis.
Journal ArticleDOI

TL;DR: The biochemistry, benefits and risks of VLCKDs are described, and recommendations on the correct use of this therapeutic approach for weight loss and management of metabolic diseases at different stages of life are provided.
Journal ArticleDOI
Endocrine control of benign prostatic hyperplasia.
TL;DR: It is clear that the BPH pathogenesis and the subsequent onset of the lower urinary tract symptoms (LUTS) depends from different etio‐pathogenetic factors whose mechanism of action remains to be evaluated.
Journal ArticleDOI
SARS-CoV-2 infection, male fertility and sperm cryopreservation: a position statement of the Italian Society of Andrology and Sexual Medicine (SIAMS) (Società Italiana di Andrologia e Medicina della Sessualità).

TL;DR: Data derived from other SARS-CoV infections suggest that in patients recovered from COVID-19, andrological consultation and evaluation of gonadal function including semen analysis should be suggested, and studies in larger cohorts of currently infected subjects are warranted to confirm the presence of risks for male gametes that are destined either for cryopreservation in liquid nitrogen or for assisted reproduction techniques.
