Treatment of palpable varicocele in infertile men: a meta-analysis to define the best technique.

To date, there have been no randomized, controlled, prospective clinical studies that compare various techniques to describe the best method for the treatment of varicocele in infertile men. This meta-analysis aims to address the best treatment modality for palpable varicocele in infertile men. A MEDLINE search was performed for articles published between January 1980 and April 2008, and we analyzed 36 studies reporting postoperative spontaneous pregnancy rates and/or complication rates after varicocele repair using various techniques in infertile men with palpable unilateral or bilateral varicocele. Spontaneous pregnancy rates and postoperative complications such as hydrocele formation, recurrence, or persistence were compared among the techniques. In addition, interventional failure with radiologic embolization and reported complications with the laparoscopic approach were reviewed. Overall spontaneous pregnancy rates were 37.69% in the Palomo technique series, 41.97% in the microsurgical varicocelectomy techniques, 30.07% in the laparoscopic varicocelectomy techniques, 33.2% in the radiologic embolization, and 36% in the macroscopic inguinal (Ivanissevich) varicocelectomy series, revealing significant differences among the techniques (P = .001). Overall recurrence rates were 14.97% in the Palomo technique series, 1.05% in the microsurgical varicocelectomy techniques, 4.3% in the laparoscopic varicocelectomy techniques, 12.7% in the radiologic embolization, and 2.63% in the macroscopic inguinal (Ivanissevich) or subinguinal varicocelectomy series, revealing significant difference among the techniques (P = .001). Overall hydrocele formation rates were 8.24% in the Palomo technique series, 0.44% in the microsurgical varicocelectomy techniques, 2.84% in the laparoscopic varicocelectomy, and 7.3% in the macroscopic inguinal (Ivanissevich) or subinguinal varicocelectomy series, revealing significant difference among the techniques (P = .001). We conclude that the microsurgical varicocelectomy technique has higher spontaneous pregnancy rates and lower postoperative recurrence and hydrocele formation than conventional varicocelectomy techniques in infertile men. However, prospective, randomized, and comparative studies with large number of patients are needed to compare the efficacy of microsurgical varicocelectomy with that of other treatment modalities in infertile men with varicocele.

The Prevalence of Female Sexual Dysfunction and Potential Risk Factors That May Impair Sexual Function in Turkish Women

Objectives: To detect the prevalence of sexual dysfunction, and also to investigate possible risk factors that may cause sexual dysfunction in the Turkish women. Materials and Methods: The study consisted of 179 women between the ages of 18 and 66 years living in households from different sociocultural areas. The women were divided into 5 groups according to their ages: 18–27 years (n = 23), 28–37 years (n = 55), 38–47 years (n = 43), 48–57 years (n = 44) and 58–67 years (n = 14). Female sexual function was evaluated with a detailed 19-item questionnaire to assess desire, arousal, lubrication, orgasm, satisfaction and pain. The prevalence of sexual dysfunction was calculated for each domain and compared among the groups. In addition, demographic characteristics and medical risk factors were assessed in all women, and the findings were compared between the women with and without sexual dysfunction. Results: Based on total sexual function score, 84 (46.9%) out of 179 women had sexual dysfunction. The prevalence of female sexual dysfunction was 21.7% in the ages of 18–27 years, 25.5% in the ages of 28–37 years, 53.5% in the ages of 38–47 years, 65.9% in the ages of 48–57 years and 92.9% in the ages of 58–67 years. The prevalence of sexual dysfunction for each domain also increased with age. To investigate various factors that may cause female sexual dysfunction, no significant differences were detected in smoking history (p = 0.14), marriage age (p = 0.7), the presence of previous pelvic surgery (p = 0.09), and contraception methods used (p = 0.31). However, sexual dysfunction was observed as significantly higher in the presence of older age (p = 0.001), lower educational level (p = 0.012), unemployment status (p = 0.017), chronic disease (p = 0.032), multiparity (p = 0.0027) and menopause status (p = 0.0001). Conclusions: The prevalence of female sexual dysfunction including desire, arousal, lubrication, orgasm, satisfaction and pain problems increases with age. In addition, the presence of a lower educational level, unemployment status, chronic diseases, multiparity and menopause status are important risk factors that may cause sexual dysfunction.

The Assessment of Sexual Functions in Women with Male Partners Complaining of Erectile Dysfunction: Does Treatment of Male Sexual Dysfunction Improve Female Partner's Sexual Functions?

The aims of this prospective study were to compare sexual functioning between women with male partners who have erectile dysfunction (ED) and women without partners with ED and also to investigate the effect of the treatment of male ED on female partners sexual function. The study included 87 women and their male partners. We divided the women into two groups: 38 women with male partners complaining of ED (ED group) and 49 women with male partners who have no ED (control group). Of the men with ED, 30 were treated with penile prosthesis implantation (n = 17) or oral sildenafil citrate (n = 13). We evaluated all the men with the International Index of Erectile Function (IIEF; Rosen, Cappelleri, Smith, Lipsky, & Pena, 1999), physical examination, and color penile Doppler ultrasound. We evaluated female sexual function with the Female Sexual Function Index (FSFI; Rosen et al., 2000) to assess sexual desire, arousal, lubrication, orgasm, satisfaction, and pain. We compared female sexual function scores between the women of the male partners with and without ED and also compared before both groups and after the treatment of male partners in the ED group. Additionally, we compare the scores according to the type of treatment given to the male partners. Sexual arousal (p = 0.009), lubrication (p = 0.001), orgasm (p = 0.006), satisfaction (p = 0.000), pain (p = 0.039), and total score (p = 0.003) were highly significantly lower in the ED group than in the control group, although sexual desire did not differ between the two groups (p = 0.515). We investigated the effect of male ED on female sexual functions and found no statistically significant differences in the presence of organic type impotence, older age, and lower erection scores on the IIEF (p = 0.53, p = 0.15, and p = 0.1, respectively). After the treatment of male ED, we observed significant improvement in sexual arousal (p = 0.001), lubrication (p = 0.002), orgasm (p = 0.000), satisfaction (p = 0.000), and pain (p = 0.002) in the women. These findings suggest that female sexual function is affected by male erection status and may improve after the treatment of male sexual dysfunction.

The prevalence of varicocele and varicocele‐related testicular atrophy in Turkish children and adolescents

Objective To determine the prevalence and site of varicocele and varicocele‐related testicular atrophy in children and adolescents.

Comparison of results and complications of high ligation surgery and microsurgical high inguinal varicocelectomy in the treatment of varicocele.

OBJECTIVES To prospectively compare sperm parameters, pregnancy and recurrence rates, and complications after randomized high ligation surgery versus microsurgical high inguinal varicocelectomy (MHIV). METHODS Varicocele was diagnosed by physical examination and color Doppler ultrasound in 468 patients who underwent one of two procedures: high ligation surgery (n = 232) or MHIV (n = 236). The high ligation surgery was left unilateral in 142 and bilateral in 90. The MHIV was left unilateral in 128 and bilateral in 108. The patients were postoperatively evaluated by spermiograms and physical examination. The pregnancy rate was monitored for 2 years. RESULTS One year after surgery, 34.05% in the high ligation group and 46.61% in the MHIV group had a more than 50% increase in their total motile sperm count (P = 0.000). The increase in sperm count was not statistically different between the two groups (P = 0.1), but the difference in the increase in sperm motility in the MHIV group was statistically significant (P = 0.000). Pregnancy rates at the end of 2 years reached 33.57% in the high ligation group and 42.85% in the MHIV group, not a statistically significant difference (P = 0.0571). The postoperative recurrence as detected by physical examination was markedly different between the two techniques. The recurrence rate was 15.51% in the high ligation group and 2.11% in the MHIV group (P = 0.000). Also, the incidence of postoperative hydrocele was significantly different between the two groups (9.09% in the high ligation group and 0.69% in the MHIV group; P = 0.000). CONCLUSIONS MHIV has lower recurrence and hydrocele rates, a higher increase in sperm motility, and results in higher pregnancy rates. Therefore, it should be the preferred technique for varicocelectomy.

Effect of Diabetes Mellitus on Female Sexual Function and Risk Factors

The study was conducted to investigate the effect of diabetes mellitus upon female sexual function, and to detect possible risk factors that might predict sexual dysfunction. The study consisted of 127 married women: 21 women with type 1 diabetes, 50 women with type 2 diabetes and 56 healthy women as a control. Female sexual functions were evaluated with a questionnaire to assess sexual desire, arousal, lubrication, orgasm, satisfaction and pain. The prevalence of sexual dysfunction was 71% in the type 1 diabetic group, 42% in the type 2 diabetic group and 37% in the control subjects. The scores for sexual desire, arousal and lubrication were significantly lower in the type 1 diabetes group than in the control subjects (p<0.05). The scores of orgasm, satisfaction, dyspareunia and total sexual function were slightly lower in the type 1 diabetic group than in the other groups. No factor predicted sexual dysfunction in the diabetic women while further age, poor education, absence of occupation and menopause predicted sexual dysfunction in the control subjects. The prevalence of sexual dysfunction was significantly higher in the type 1 diabetic women than in the type 2 diabetics and control subjects. However, no risk factors that might cause sexual dysfunction could be predicted in diabetic women.

CAN VARICOCELECTOMY SIGNIFICANTLY CHANGE THE WAY COUPLES USE ASSISTED REPRODUCTIVE TECHNOLOGIES

PURPOSE We assessed how varicocelectomy alters semen quality in a large cohort of infertile men and determined whether it can change patient candidacy for assisted reproductive technology procedures. MATERIALS AND METHODS A cohort of 540 infertile men with clinical palpable varicocele underwent microsurgical varicocelectomy and were followed more than 1 and 2 years postoperatively for alterations in semen quality and conception, respectively. Preoperatively and postoperatively the total motile sperm count was calculated in all semen analyses. Based on total motile sperm count values patients were divided into 4 groups according to the type of assisted reproductive technology for which they qualified, including 0 to 1.5 million or less (intracytoplasmic sperm injection candidates), 1.5 to 5 million or less (in vitro fertilization candidates), 5 to less than 20 million (intrauterine insemination candidates) and 20 million or greater sperm (spontaneous pregnancy candidates). Preoperative and postoperative semen quality was compared among individuals in these cohorts to determine the shifts in assisted reproductive technology care that are possible after varicolectomy. RESULTS Mean patient age was 29.5 years (range 18 to 58). Microsurgical varicocelectomy was bilateral in 393 patients (73%), on the left side in 146 (27%) and on the right side in 1 (0.2%). A positive response to varicocelectomy, defined as a greater than 50% increase in total motile sperm count, was observed in 271 patients (50%). An overall spontaneous pregnancy rate of 36.6% was achieved after varicocelectomy with a mean time to conception of 7 months (range 1 to 19). Of preoperative in vitro fertilization and intracytoplasmic sperm injection candidates 31% became intrauterine insemination or spontaneous pregnancy candidates after varicolectomy. Of intrauterine insemination candidates 42% gained the potential for spontaneous pregnancy. CONCLUSIONS Varicocelectomy has significant potential not only to obviate the need for assisted reproductive technology, but also to down stage or shift the level of assisted reproductive technology needed to bypass male factor infertility.

The effect of testosterone therapy on lower urinary tract symptoms/bladder and sexual functions in men with symptomatic late-onset hypogonadism

Objective. To prospectively investigate the effect of testosterone therapy on lower urinary tract symptoms (LUTS)/bladder and sexual functions in men with symptomatic late-onset hypogonadism (SLOH). Methods. The study included 25 men (age range 38 to 73 years) presented with sexual dysfunction, having SLOH, at a single university hospital. All men received testosterone replacement therapy with transdermal testosterone 50–100 mg gel per day for one year. Urodynamic studies with pressure-flow analysis, measurement of prostate volume, prostate specific antigen (PSA) and free PSA level, International Prostate Symptom Score (IPSS), Aging Male Symptom (AMS) scale and International Index of Erectile Function (IIEF-5) score were recorded in all men before and after one year of the treatment. Results. The mean AMS score significantly decreased from 40.4 ± 7.3 to 28.8 ± 5.31 (p = 0.001), and mean IIEF-5 score significantly increased from 8.84 ± 3.76 to 14.36 ± 3.62 (p = 0.001). The mean maximal bladder capacity and compliance significantly increased (p = 0.007 and p = 0.032, respectively), and mean detrusor pressure at Qmax significantly decreased from pre-treatment to post-treatment (p = 0.017). Conclusion. This study suggests that in addition to improvement in sexual functions, testosterone therapy may also improve LUTS/bladder functions by increasing bladder capacity and compliance and decreasing detrusor pressure at maximal flow in men with SLOH.

The Effect of Varicocele Repair on Testicular Volume in Children And Adolescents With Varicocele

PURPOSE We investigated the effect of varicocele repair on testicular volume according to age in children and adolescents and review the long-term results of varicocele surgery. MATERIALS AND METHODS The study included 39 boys 11 to 19 years old with clinical palpable varicocele who underwent varicocele surgery with at least 1 year of postoperative followup. Preoperative and postoperative testicular volumes were monitored and measured with an ellipsoid Prader orchidometer. Physical examination findings (testicular volumes and testicular consistency) in all boys, and serum hormone values and semen parameters in 16 adolescents were recorded and compared before and after surgery. RESULTS Left unilateral varicocelectomy was done in 29 boys (74%) and bilateral varicocelectomy in 10 (26%). While no postoperative hematoma, infection or testicular atrophy was observed, 1 boy (2.5%) had varicocele recurrence and 2 boys (5.1%) had minimal hydroceles that required no intervention. Significant increases were observed in postoperative sperm concentration (p = 0.01), total motile sperm count (p = 0.009), testis volume (p = 0.000) and serum testosterone level (p = 0.014). All 15 boys with preoperative soft testis had normal testicular consistency postoperatively. Of the 19 boys with preoperative testicular atrophy 10 (53%) did regain normal testicular growth, while 9 (47%) retained testicular volume loss after surgery. When comparing preoperative to postoperative increase in testicular volume according to age in all boys, the mean was statistically significantly higher in boys younger than 14 years (left testis p = 0.037, right testis p = 0.000). CONCLUSIONS Testicular consistency achieved normal firmness after varicocelectomy in all boys with preoperative soft testis. While there was catch-up growth in comparison to the contralateral testis, testicular consistency improved but testicular volumes may not increase significantly after varicocele repair at ages older than 14 years. However, in these adolescents postoperative semen parameters and serum hormone values may significantly improve regardless of testicular volume. Therefore, boys with varicocele and their families should be fully informed in light of these findings.

Prevalence of the Complaint of Ejaculating Prematurely and the Four Premature Ejaculation Syndromes: Results from the Turkish Society of Andrology Sexual Health Survey

INTRODUCTION In addition to the previously known lifelong and acquired premature ejaculation (PE) syndromes, the existence of two more PE syndromes has been suggested: natural variable PE and premature-like ejaculatory dysfunction. However, epidemiological studies investigating the prevalence of these four PE syndromes have yet to be conducted. AIM To determine the prevalence of the complaint of ejaculating prematurely across the four PE syndromes. METHODS This study, conducted between June 2009 and December 2009, was designed as a non-interventional, observational cross-sectional field survey. Participating couples were randomly selected from 17 provinces of Turkey. All participants were asked to complete a questionnaire including data regarding demographics, socioeconomic status, social and cultural factors, medical and sexual history, current medications, and ejaculation time. Subjects with a complaint of ejaculating prematurely were classified as lifelong, acquired, and natural variable PE, or premature-like ejaculatory dysfunction. MAIN OUTCOME MEASURES The main outcome measures were prevalence of complaint of ejaculating prematurely in the general population and across the four PE syndromes. RESULTS A total of 2,593 couples (mean age, 41.9±12.7 years for males and 38.2±12.1 years for females) were enrolled. Five-hundred twelve subjects (20.0%) complained of ejaculating prematurely. Fifty-eight (2.3%), 100 (3.9%), 215 (8.5%), and 131 (5.1%) subjects were classified as lifelong, acquired, and natural variable PE, and premature-like ejaculatory dysfunction, respectively. CONCLUSIONS The prevalence of the complaint of ejaculating prematurely among Turkish men was 20.0%, with the highest PE syndrome being natural variable PE (8.5%) and premature-like ejaculatory dysfunction (5.1%).
