Semen analysis, especially sperm counting, is an important test performed in andrology laboratories. Due to the unavailability of external proficiency testing programs for semen analysis, it has recently been shown that there is wide variation in sperm counts between these laboratories. 1,2 Moreover, this variability is expected to adversely impact patient… (More)
This study investigated the effect of annexin V on the proliferation of primary rat Leydig cells and the potential mechanism. Our results showed that annexin V promoted rat Leydig cell proliferation and cell cycle progression in a dose- and time-dependent manner. Increased level of annexin V also enhanced Ect2 protein expression. However, siRNA knockdown of… (More)
In this age of evidence-based medicine, there is nothing more important than the quality of lab tests (Westgard and Darcy, 2004). However, reliability of semen analysis has been suspected for lack of standardization , and significant variation exists within the same laboratory and among different laboratories (Chong et In recent years, andrologists have… (More)
INTRODUCTION The relationships of the biochemical components in seminal plasma and serum, and their origins and physiological effects in male reproductive system have been poorly understood. METHODS Based on the calibration and quality control measures, 26 biochemical markers, in seminal plasma and serum samples from 36 male infertility patients with… (More)
OBJECTIVE This prospective study was designed to investigate the relationship between lipids levels in both serum and seminal plasma and semen parameters. METHODS 631 subfertile men were enrolled. Their obesity-associated markers were measured, and semen parameters were analyzed. Also, seminal plasma and serum TC, TG, HDL and LDL and serum FFA, FSH, LH,… (More)
