PURPOSE: It has been reported that varicocele is found less frequently in obese men. Accordingly, we evaluated varicocele patients and statistically analyzed the correlation between varicocele and somatometric parameters. MATERIALS AND METHODS: A total of 211 patients underwent surgery for varicoceles. All patients underwent history taking, physical examination, and scrotal ultrasound to determine the presence and severity of varicocele. An age-matched control group consisted of 102 patients who were found not to have varicocele according to physical examinations and scrotal ultrasound. The age, weight, height, and body mass index (BMI) of the two groups were compared. The statistical analyses were performed by use of PASW Statistics ver. 18.0. A p-value of less than 0.05 was used for statistical significance. RESULTS: In the varicocele group, the mean age, height, weight, and BMI were 29.42+/-14.01 years, 168.53+/-9.97 cm, 62.14+/-13.17 kg, and 21.66+/-3.21 kg/m2, respectively. The distribution of varicocele grade was as follows: 103 (48.8%) grade III, 72 (34.1%) grade II, and 36 (17.1%) grade I. In the control group, the mean age, height, weight, and BMI were 30.83+/-17.31 years, 161.93+/-19.83 cm, 64.69+/-17.86 kg, and 24.04+/-3.64 kg/m2, respectively. Analyzing these data specifically in adolescents, they showed significant differences in age, height, and BMI (p=0.000, p=0.000, and p=0.004, respectively) between two groups. There were no significant differences in somatometric parameters between patients with different grades of varicocele. CONCLUSIONS: Our results showed that patients with varicoceles were significantly taller and had a lower BMI than did patients without varicoceles, especially among adolescents. Carefully designed future studies may be needed.

The purposes of this study were to evaluate the effects of insulin-like growth factor (IGF)s in peritoneal fluid (PF) from patients with and without endometriosis on the proliferation of endometrial stromal cells and to investigate the effects of type I IGF receptor antibody on the response of endometrial stromal cells to PF from patients with endometriosis. IGFs in PF from patients with endometriosis (n=14) and without endometriosis (n=10) were measured by immunoradiometric assay and PF samples were divided into low IGF-I PF group (less than 85 ng/ml) and high IGF-I PF group (more than 85 ng/ml). Endometrial stromal cells from patients without endometriosis were cultured in serum free media in the presence or absence of 1% PF and thymidine incorporation test were used to evaluate the proliferation of endometrial stromal cells. Also cultures were incubated with type I IGF receptor monoclonal antibody (alpha IR3) before adding PF. PF from patients with endometriosis and without endometriosis increased thymidine incorporation in endometrial stromal cells. In patients with endometriosis, high IGF-I PF group had high IGF-II levels and resulted in higher thymidine incorporation than low IGF-I PE and low IGF-I PF group was noted in patients without endometriosis. There was not a significant correlation between increase in thymidine incorporation and IGF-I levels in PF from patients without endometriosis but in PF from patients with endometriosis. Preincubation with alphaIR3 significantly inhibited the mitogenic response of endometrial stromal cells to PF. Our data indicate that IGF-I in PF may be involved in the growth of ectopic endometrium in patients with endometriosis.

BACKGROUND: Sex steroid hormones are believed to play an important role in the genesis and growth of uterine myoma. Several studies suggest a possible role of insulin-like growth factor(IGF) as a mediator of estradiol in uterine myama. We have recently demonstrated that some IGF binding proteins(IGFRPs) messenger ribonucleic acid(mRNA) expressions in myoma are dependent on the in vivo esttogen status. The purposes of this study are to evaluate the in vitro effects of sex steroid hormones including estrogen on the IGFBPs gene expression in tissues from uterine myoma and adjacent normal myometrium. METHODS: Tissues from myoma and adjacent normal myometrium of patients with uterine myoma during early proliferative phase of menstrual cycle were cultured in the absence(control) and presence of 17b-estradiol(10M/L) or/and progesterone(10M/L) for 3 days. The IGFBPs mRNA expressions in these explants were analyzed by Nothern blot using specific human complementary deoxyribonucleic acid(cDNA) probes. RESULTS: The addition of 17b-estradiol, progesterone alone and in combination to conditioned media of explants from myoma and adjacent normal myornetrium did not result in any changes in the expression of IGFBP-2, IGFBP-4, IGFBP-5, and IGFBP-6 mRNA. With progesterone addtion, lGFBP-3 rnRNA expression was significantly reduced in myoma explant but not in adjacent ncemal myometrium explant. There was no significant change in the IGFBP-3 mRNA expression with 17b-estradiol and with the combination of both 17b-estradiol and progesterone. CONCLUSION: 17b-estradiol does not affect IGFBPs gene expression in the myoma and adjacent normal myometrium explant regardless of the presence of progesterone in vitro. However progesterone alone induces a decrease in IGFBP-3 synthesis in myoma explant.
