Filter by:Varicocele is the most common surgical disease which could lead to male infertility. It is found in approximately 15% adult males, and in about 40% infertile males. And the incidence is up to 80% in secondary infertility. In the past, there was continuous controversy over whether a varicocele repair could improve fertility. But at present, researches are coming to a consensus on the indication of varicocelectomy. Several researches manifest that the microsurgery of varicocele could have the effect of the highest spontaneous pregnancy and lowest complications rate after surgery. Microsurgical varicocelectomy includes two approaches, inguinal and subinguinal. Each one has its advantages and disadvantages. There are few studies which make direct comparison between the two methods in microsurgical varicocelectomy, especially in China. Operators have made decisions on the basis of their own experience and skills. In this study, the investigators compare the postoperative spontaneous pregnancy and complications rates in two approaches in microsurgical varicocelectomy for Chinese infertile men in their hospital.
The purpose of this study is to determine if the pre-operative levels of sex-hormones can be used to identify the varicocele patients who can expect improvements in their semen parameters following varicocelectomy.
We prospectively compared outcomes of subinguinal varicocelectomy for 40 patients who received 2 ml intratunical space injection of methylene blue before spermatic vein ligation with 40 controls in whom no mapping technique was adopted in the period between January 2008 and Feb. 2010, in Mansoura university hospital ward 7.After surgery, the patients were assessed at 2 weeks,6 and 12 months for varicocele recurrence, hydrocele formation, atrophy, pain or other complications with mean follow up was 15+ 7months.
A varicocele is the presence of dilated testicular veins in the scrotum. Although it is generally agreed that a varicocele is the most common identifiable pathology in infertile men (detected in up to 40% of men in some series of men with infertility), the influence of a varicocele on male fertility potential and role of varicocelectomy in restoring of fertility remain the subject of ongoing controversy. The present controversy on the effect of varicocelectomy on male fertility potential has led many clinicians to dismiss the diagnosis of a varicocele altogether and instead, offer alternative treatments to the couple. Many of these alternative therapies are expensive and risky for the patients and their children. Several recent reviews have critically examined the results of randomized, controlled trials of varicocelectomy on fertility potential. The effect of varicocelectomy on spontaneous pregnancy rates remains controversial. The investigators hypothesize that a varicocelectomy will result in a significant improvement in fertility and testicular function in infertile men with a clinical varicocele.
The primary research hypothesis is that microsurgical varicocelectomy will result in an increase in live birth in infertile couples where the male partner has a palpable varicocele and an abnormal semen analysis in comparison to male partners who do not have microsurgical varicocelectomy. The secondary hypotheses include: 1. To assess whether up to 4 cycles of intrauterine insemination confers any additional increase in live birth rates compared to timed intercourse; 2. To examine spousal pregnancy rate as the secondary outcome; and 3. To study the effect of varicocelectomy in men with infertility, an abnormal semen analysis, and a palpable varicocele on - Testicular semen analysis parameters; - Serological measures of FSH, LH, total and free testosterone and - Measures of quality of life and sexual function in both partners.
In varicocele the venous pressure in the prostatic bed is increased .This may result in raised hydrostatic pressure which in turn may stimulate prostatic hypertrophy. Restoring normal venous drainage is expected to lower hydrostatic pressure followed by inhibition of prostatic growth and possibly leading regression in prostatic dimensions.
Patients with varicocele in whon early prostate cancer will be found will undergo venographic embolization of both spermatic veins. The study hypothesis is that this procedure will induce a gradual regression of the prostate volume that may decrease prostate cancer cells. Close follow-up will ensure that necessary therapy will be provided if needed according to clinical criteria. Results in terms of prostate size PSA level and tumor size will be recorded.
Varicose veins in the scrotum (varicocele) are responsible for >20% of male infertility in the US. Varicocele are associated with decreased sperm number and markedly reduced sperm fertilizing ability. Surgical repair or removal of varicocele restores fertility in only 1/3 of cases. The goal of this study is to identify markers that predict the outcome of variocele correction. This would offer considerable health cost savings. Based on preliminary findings, we will obtain testis biopsies and semen specimens from infertile men with varicocele and prospectively examining the levels of cadmium, a toxic metal, and expression of genes required for normal sperm function. The semen and biopsies will be obtained during clinically dictated procedures. Cadmium and gene expression will be compared with response to varicocele repair (i.e., increased sperm production; pregnancy).
