Observational Study
Assessment of Time-dependent Changes in Semen Parameters in Infertile Men After Microsurgical Varicocelectomy.
To characterize the changes in seminogram findings in infertile men after varicocelectomy. ⋯ The level of improvement in semen parameters at 3 months after varicocelectomy may be stable at 12 months after surgery, irrespective of baseline values of TMSC. Therefore, varicocelectomy could be offered as a therapeutic option for infertile men, even for couples with an older woman, because its efficacy is evaluable at 3 months after surgery, and assisted reproductive technology could be immediately applied to ineffective cases.

Randomized Controlled Trial Multicenter Study Observational Study
Association Between Dosage Frequency and the Treatment Outcomes of Sildenafil in Young and Middle-aged Men With Erectile Dysfunction: A Chinese, Multicenter, Observational Study.
To evaluate the correlation between the dosage frequency of sildenafil and its treatment outcomes in men with erectile dysfunction (ED). ⋯ Higher dosage frequency of sildenafil is associated with a better improvement of sexual function and quality of life of men with ED, and the concomitant treatment of hyperlipidemia is recommended.

Randomized Controlled Trial
Can Sexual Intercourse Be an Alternative Therapy for Distal Ureteral Stones? A Prospective, Randomized, Controlled Study.
To investigate the effect of sexual intercourse on spontaneous passage of distal ureteral stones. ⋯ Our results have indicated that patients who have distal ureteral stones ≤6 mm and a sexual partner may be advised to have sexual intercourse 3-4 times a week to increase the probability of spontaneous passage of the stones.

Randomized Controlled Trial
Adenotonsillectomy Normalizes Hormones and Urinary Electrolytes in Children With Nocturnal Enuresis and Sleep-Disordered Breathing.
To assess (1) plasma levels of antidiuretic hormone (ADH) and brain natriuretic peptide (BNP) and urinary levels of electrolytes in children with sleep disordered breathing (SDB), with or without nocturnal enuresis (NE), and (2) the effect of adenotonsillectomy (T&A) on urinary electrolytes and the secretion of ADH and BNP in children with NE and SDB. We previously reported post-T&A improvements in plasma levels of BNP and ADH in children with SDB and NE. However, the differences in plasma concentration of these hormones in SDB children with and without NE, and their relationships with urinary electrolytes, have not yet been addressed. ⋯ The presence of NE is associated with altered ADH and BNP levels in children with SDB. T&A led to normalization of ADH and BNP, probably through a calcium- and sodium-dependent mechanism.
