ABSTRACT

<p><b>OBJECTIVE</b>To summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD).</p><p><b>METHODS</b>We retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle.</p><p><b>RESULTS</b>After 28 cycles of ICSI, 10 of the 15 ADPKD-induced infertility patients achieved clinical pregnancy, including 7 cases of live birth, 1 case of spontaneous abortion, and 2 cases of pregnancy maintenance. No significant differences were observed between groups A and B in the couples' age, the wives' BMI, or the numbers of ICSI oocytes and embryos transplanted (P >0.05), nor in the rates of ICSI fertilization (72.64% vs 76.17%), transferrable embryos (51.28% vs 63.24%), quality embryos (38.46% vs 49.83%), embryo implantation (17.64% vs 38.50%), abortion (0 vs 9.23%), singleton (50% vs 81.54%) and twins (50% vs 18.46%). However, the rates of clinical pregnancy (13.33% vs 42.68%, P = 0.023 <0.05) and biochemical pregnancy (13.33% vs 39.63%, P = 0.032 <0.05) were significantly lower in group A than in B.</p><p><b>CONCLUSION</b>ICSI is effective in the treatment of male infertility induced by either ADPKD or CBAVD, but the ADPKD cases have a lower success rate than the CBAVD cases in an individual cycle. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the safety and feasibility of testis-sparing surgery (TSS) in the treatment of testicular tumor.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 8 cases of benign testicular tumor treated by TSS in our hospital from October 2005 to March 2012.</p><p><b>RESULTS</b>The 8 patients, aged 18-67 (mean 45) years, were preoperatively diagnosed with benign testicular tumor and all underwent partial testis resection. Rapid intraoperative pathology showed the incisal margins to be negative. Postoperative pathological examination confirmed Sertoli cell tumor in 3 cases, adenomatoid tumor in another 3, and mature teratoma in the other 2. The patients were followed up for 6 months to 7 years (mean 4 years), which revealed no relapse and metastasis, nor significant differences from the baseline in the testosterone level, IIEF score, and routine semen parameters.</p><p><b>CONCLUSION</b>Testis-sparing surgery is one of the effective options for the management of benign testicular tumor, which can maximally preserve the testis tissue and protect the patient's sexual function.</p>

ABSTRACT

DAZL, a member of the DAZ family, plays a key role in human spermatogenesis. It regulates the promoter via genetic modification, especially DNA methylation, promoting the transcription of DAZL. Besides, the relation of DAZL SNPs with male infertility has been a hot spot of research for many years. It is deduced that local and ethnic factors may be associated with the failure of spermatogenesis. This article presents an overview on the results of recent studies, changes in the DNA methylation of DAZL in spermatogenesis, and the association of DAZL SNPs with male infertility, aiming to provide a new theoretical basis and clinical strategy for the treatment of male infertility.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical effect and application value of the modified method of prepuce-degloving repair (PDR) in the treatment of urethrocutaneous fistula (UCF) following hypospadias surgery.</p><p><b>METHODS</b>We retrospectively analyzed 87 cases of UCF caused by hypospadias repair from May 2001 to December 2011, of which 61 were treated by simple closure or Y-V plasty of the fistula (group A), and the other 26 by modified PDR (group B). We compared the success rate of surgery and long-term recurrence between the two groups.</p><p><b>RESULTS</b>The total success rates of repair were 78.7 and 96.2% in groups A and B, respectively. Thirteen cases in group A did not respond to surgery, of which 6 failed to be cured by the second operation but later were treated successfully by modified PDR. In comparison, there was only 1 case of failure in group B, which was cured by a second PDR.</p><p><b>CONCLUSION</b>Modified PDR can significantly improve the success rate and reduce the recurrence rate of UCF after hypospadias surgery, which deserves wide clinical application.</p>

ABSTRACT

There are over 200 secretive proteins in the epididymis. Spermatozoa are generally considered to become mature and full-functional after interacting with secretive proteins in the epididymis. This review is aimed at summarizing some aspects of the biochemical, molecular and functional characterization of some new proteins recently detected in human epididymis, and is expected to contribute to further researches on the mechanism of epididymal reproduction and contraception.
