Testosterone has now become one of the most widely used medications throughout the world. The rapid growth of the testosterone market in the past 10 years is due to many factors. We currently have a worldwide aging population. In the US, the number of men 65 years old or older is increasing 2-3 times faster than the number of men younger than 65 years. In addition, poor general health and certain medical conditions such as diabetes/metabolic syndrome （MetS）, cardiovascular disease （CVD）, and osteoporosis have been associated with low serum testosterone levels？-3 There are now fewer concerns regarding the development of prostate cancer （PCa） after testosterone therapy, making it a more attractive treatment option. Finally, the introduction of different forms of testosterone supplementation therapy （TST） with increased promotion, marketing, and direct-to-consumer advertising is also driving market growth. As the demand for TST continues to grow, it is becoming more important for clinicians to understand how to diagnose and treat patients with low testosterone.

For more than 70 years, it has been believed that a severe reduction of serum androgen levels caused regression of prostate cancer （PCa） and that increasing androgen levels enhanced growth of PCa. However, numerous recent studies have questioned this traditional belief. In our study, LNCaP and MDA PCa 2b PCa cells were treated with various levels of androgens for 10 or 20 days, and the cell growth was measured with crystal violet mitogenic assay. The results indicated that the effect of androgens on the proliferation of PCa cells occurs in a biphasic pattern, with the androgen levels promoting optimal cell growth at approximately 0.23 ng m1-1 for LNCaP cells and between I and 2 ng m1-1 for MDA PCa 2b cells. Both of the optimal androgen levels are within the adult men＇s physiological low range （〈2.4 ng ml-1）. At lower concentrations than the optimal androgen level, increasing androgen concentration promoted the proliferation of PCa cells. However, at the higher concentrations, increasing androgen concentration resulted in a dose-dependent proliferative inhibition. We conclude that physiologically normal levels of androgen inhibit the proliferation of PCa cells in vitro. However, at very low levels androgens are essential for initial growth of PCa cells.

Cholelithiasis and choledocholithiasis occur frequently in pregnancy and their management can be complicated. Traditional endoscopic retrograde cholangiopancreatography(ERCP)is the first line treatment for choledocholithiasis,but in addition to its baseline risks,fluoroscopy poses an additional radiation risk to the fetus. Endoscopic ultrasound(EUS)is an accurate modality for detecting common bile duct stones,but its role has not been defined in *** describe an alternative management strategy to conventional ERCP in a pregnant patient with choledocholithiasis and cholangitis detected using EUS and choledochoscopy.
