TL;DR: Current evidence suggests a beneficial effect of varicocelectomy on semen quality and pregnancy outcomes in couples with documented infertility only if the male partner has a clinically palpable varicocele and affected semen parameters.

Varicoceles: prevalence and pathogenesis in adult men
TL;DR: The prevalence ofvaricocele in adults, the anatomic features of varicocele, the leading theories as to how varicoCele can negatively affect fertility potential, and the current literature on the impact of varICOcele on testosterone production are discussed.

A Critical Evaluation of Simple Methods for the Estimation of Free Testosterone in Serum
TL;DR: The FT value, obtained by calculation from T and SHBG as determined by immunoassay, appears to be a rapid, simple, and reliable index of bioavailable T, comparable to AFTC and suitable for clinical routine, except in pregnancy.

TL;DR: Semen quality of the reference population was superior to that of the men from the general population and normozoospermic men, and provide an appropriate tool in conjunction with clinical data to evaluate a patient's semen quality and prospects for fertility.

TL;DR: The study suggests that the current WHO guidelines for normal semen quality should be used with caution, as some men with sperm counts above the lower limit of the normal range defined by WHO may in fact be subfertile.
