Clomiphene citrate (CC) is commonly used off-label for the treatment of male infertility, yet there is limited data to guide patient selection. To identify a subset of patients more likely to benefit from CC, we aimed to define predictors of improvement in semen parameters among men receiving CC. We retrospectively analysed 151 men treated with at least 25 mg CC daily for male infertility and/or hypogonadism at two institutions between 2004 and 2014. Men previously on testosterone were excluded. The primary outcome was change in semen parameters...

Garrett K Berger, Luriel I Smith-Harrison, Jay I Sandlow
Agglutination is a finding noted in semen analyses (SAs) that often causes confusion as to its significance. While some have attributed agglutination to antisperm antibodies (ASAs), there are other causes as well, such as genital tract infection and ascorbic acid deficiency. Additionally, it is known that patients with ASAs often have risk factors such as a history of scrotal trauma or surgery. Therefore, we sought to determine the prevalence of agglutination in our patient population and correlate it with these risk factors, regardless of the presence/absence of ASAs...

BACKGROUND: Klinefelter syndrome(KS), affecting 1 in 500-1,000 newborn males, is the most common sex chromosome aneuploidy among males with primary hypogonadism. Isochromosome Xq on the other hand is a rare variant of Klinefelter syndrome, accounting approximately 0.3% of all KS and associated with normal height and androgenisation compared to classical KS. Here, we present a case of isochromosome Xq variant of KS with similar clinical and cytogenetic findings with the few cases reported before...

Elevated platelet levels have been postulated to be associated with cardiovascular diseases, conditions closely linked to erectile dysfunction (ED). The current systematic review and meta-analysis was performed to assess the platelet indices, which including platelet count (PLT), mean platelet volume (MPV) and platelet distribution width (PDW) in subjects with ED compared to controls in an attempt to clarify the possible role of platelet indices in the pathogenesis of ED. We initially screened the candidate studies observing the possible association between platelet indices and ED following literature search of database Cochrane Library, PubMed, EMBASE and MEDLINE and therefore included the studies based on the pre-defined inclusion and exclusion criteria...

There is a scarcity of morphometric data on the developmental and ageing changes in the epididymis and seminal vesicle in young and old rats. Eighty-six normal male Sprague-Dawley rats were randomly sampled from a cohort of animals aged 1-36 months (7-9 animals each age group). The epididymis and seminal vesicle (with the closely attached coagulating gland) were removed, and methacrylate resin-embedded sections were prepared for quantitative study of key histological structures by light microscopy. Stereological methods (point counting and optical disector) were used to estimate the total volumes of sperm mass, secretion (glandular lumen) and other structures and the number of spermatozoa...

Pre-treatment of boar semen with a red light photostimulation procedure increases its "in vivo" fertilising ability. However, "in vitro" conducted studies shown contradictory results regarding the ability of photostimulated spermatozoa to react against strong stress and to achieve the capacitation status. The aim here was to determine the effect of photostimulation on the response to short-term moderate thermal stress of boar semen. Boar semen was exposed to red LED light regime emitting a 620-630 nm during 10 min of light, 10 min of rest and 10 min of light after 3 hr since semen was collected...
