ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of penile frenulum lengthening in the treatment of premature ejaculation (PE).</p><p><b>METHODS</b>Thirty-four males with PE were enrolled in this study, of whom 8 had received circumcision six months before and 4 had redundant prepuce, all with short frenulum. Those with a history of circumcision underwent reconstruction and lengthening of the frenulum, and those without received frenulum lengthening only.</p><p><b>RESULTS</b>Compared with the baseline, the intravaginal ejaculation latency time (IELT) was significantly increased at 1 month after operation ([1.35 ± 0.49] vs [5.71 ± 2.69] min, t = -9.42, P <0.01), (1.42 ± 0.5) vs (5.31 ± 2.74) min in the patients without circumcision (t = -7.41, P <0.01), (1.12 ± 0.35) vs (7.00 ± 2.20) min in those with circumcision (t = -7.24, P <0.01), and (1.50 ± 0.58) vs (4.75 ± 1.71) min in those with redundant prepuce (t = -3.81, P <0.05). Totally, 94% of the patients were satisfied with their sexual intercourse postoperatively.</p><p><b>CONCLUSION</b>Penile frenulum plays an important role in penile erection. Reconstruction and/or lengthening of the frenulum can prolong penile erection and IELT in PE patients.</p>

<p><b>OBJECTIVE</b>To determine a complex chromosomal rearrangement by advanced molecular cytogenetic techniques and analyze its clinical effect.</p><p><b>METHODS</b>A complex chromosomal rearrangement (CCR) involved in chromosomes 5, 16 and 20 in a 29-year-old male carrier was determined by chromosomal microdissection and multicolor fluorescence in situ hybridization (M-FISH), and family degree investigation was further performed.</p><p><b>RESULTS</b>The karyotype of the case was a complex chromosomal translocation among chromosomes 5, 20 and 16, and accompanied with a band of chromosome 20 inserted into chromosome 5. His mother and sister both had the same abnormal karyotype by familial investigation.</p><p><b>CONCLUSION</b>The combined use of M-FISH and chromosome microdissection is a powerful tool to determine CCR. The complex chromosomal rearrangement could be transmitted stably in the family, but still the carriers could give birth to a healthy baby by chance.</p>

OBJECTIVE@#To explore the relationship between chromosome anomaly and spontaneous abortion, and to provide useful information for genetic counseling and prenatal diagnosis in reproductive clinic.@*METHODS@#A total of 1 780 patients who had a history of spontaneous abortion before 24 weeks of gestation were enrolled. The lymphocyte culture and harvest were performed according to standard methods. Karyotypes were analyzed by G-banding in all cases and C- banding in some cases in addition.@*RESULTS@#Altogether 57 abnormal karyotypes were found and the overall incidence of chromosomal abnormalities was 3.20% (women 3.32%; men 2.12%). Among them 23 cases were the balanced translocation; 14 cases were the Robertsonian translocation, 3 cases were the complex chromosomal rearrangement, and the other 17 cases were the other abnormalities. In women with 1, 2, 3 or more spontaneous abortion, the incidence of chromosomal abnormalities was 1.7%, 2.3%, and 5.8%, respectively.@*CONCLUSION@#Translocations are the major abnormal karyotpes associated with spontaneous abortions. The chance of finding chromosomal aberration increases with the number of abortions. Chromosomal abnormalities are more common in women with 3 or more spontaneous abortions.
