Adding sildenafil vaginal gel to clomiphene citrate in infertile women with prior clomiphene citrate failure due to thin endometrium: a prospective self-controlled clinical trial.

ABSTRACT: We aimed to investigate the effect of adding sildenafil vaginal gel to clomiphene citrate (CC) in infertile women with prior CC failure. METHODS:This is a self- controlled clinical trial. Women with CC failure (in prior 5 cycles) and thin endometrium were recruited (N = 42). In their 6th (CC only) cycle, women continued on CC 100 mg/ day for 5 days, and had measurement of endometrial thickness and Doppler assessment of uterine arteries on day of HCG administration. In the 7th cycle, women (N = 36) were given usual dose of CC supplemented with sildenafil vaginal gel (5 gm, containing 50 mg sildenafil) twice daily from cycle day 8 to day of HCG administration. Endometrial thickness and uterine artery Doppler were measured on the day of HCG injection. RESULTS:In the 7th (CC + sildenafil vaginal gel) cycle, endometrial thickness was significantly higher than in the 6th (CC only) cycle (9.3 mm +/- 3.1mm versus 6.6 mm +/- 1.4 mm, respectively, P = < 0.001). Uterine artery pulsatility index dropped from 2.4 +/- 0.8 in 6th cycle to 1.6 +/- 1.3 in 7th cycle (P = 0.002). Clinical pregnancy rate increased but numbers were too small (only 3 pregnancies). CONCLUSION:Sildenafil vaginal gel significantly increased endometrial thickness and uterine blood flow, and may improve pregnancy rate in patients with CC failure due to thin endometrium. Mucoadhesive vaginal gel formulation allowed shorter duration of sildenafil application, and less frequent daily dosing.

Project description:Introduction: Which is optimal to treat clomiphene citrate-resistant polycystic ovary syndrome (CCR-PCOS) with LOD or metformin remains a problem. There are three inconsistent or even contradictory views. Objectives: The present meta-analysis aimed to evaluate the effectiveness and safety of Metformin with or without CC and to compare them with LOD with or without CC (Met/Met-CC vs. LOD/LOD-CC) in women with CCR-PCOS who also have anovulation. Data source: The PubMed, Cochrane, and Embase databases were searched to identify relevant studies reported between 1 Jan 1966 and 31 Aug 2019; the search was updated on 17 May 2022. Study eligibility criteria: We included randomized controlled trials (RCTs) of CCR-PCOS that had considered Met/Met-CC and LOD/LOD-CC as the exposure variables and fertility as the main outcome variable. Study appraisal and synthesis methods: We assessed study quality using the Cochrane risk-of-bias tool. The primary effectiveness outcome was live birth/ongoing pregnancy rate and the primary safety outcome was miscarriage rate. A fixed-effect meta-analysis was performed. The robustness of the results was assessed using sensitivity analyses. Meta-regression and subgroup analysis were performed to examine the reasons for heterogeneity. Publication bias was examined using the funnel plot, Egger linear regression, and Begg rank correlation tests. The quality of this meta-analysis was estimated according to the GRADE approach. This meta-analysis has been registered in PROSPERO (CRD42021240156). Results: Among 71 potentially relevant studies, we included five RCTs in our meta-analysis. We found no difference in effectiveness between Met-CC and LOD in terms of live birth/ongoing pregnancy (RR = 1.02, 95% CI: 0.87-1.21, z = 0.28; p = 0.780), and miscarriage rates (RR = 0.79, 95% CI: 0.46-1.36, z = 0.86; p = 0.390). I2 tests results revealed moderate or no heterogeneity (I2 = 51.4%, p = 0.083; I2= 0.0%; p = 0.952). Sensitivity analysis confirmed the robustness of the results. Funnel plot, Egger linear regression, and Begg rank correlation tests implied no publication bias (p > 0.05). LOD was more expensive than Met (€1050 vs. €50.16). The evidence quality was moderate. Conclusion: There is no evidence on the difference in the outcomes between the two interventions regarding ovulation, pregnancy, and live birth. As LOD is an invasive procedure and carries inherent risks, the use of Met/Met-CC should be the second-line treatment for women with CCR-PCOS.

Project description:Background:Clomiphene citrate (CC) is a selective estrogen receptor modulator (SERM) used to stimulate ovulation in women. CC is used off-label in men to increase levels of endogenous testosterone (T) while potentially improving semen parameters by downregulating the inhibitory feedback of estradiol (E) on the male hypothalamus. Our objective was to determine whether pre-treatment E level is associated with greater total testosterone (TT) response to treatment with CC in men with low T. Methods:Following IRB approval (The University of Miami IRB No. 20170849), retrospective chart review was performed for all men prescribed CC (25 mg every other day) between January 1, 2015 and December 31, 2018. Age, body mass index (BMI), and prescription date were recorded for all patients. Pre- and post-treatment E, total T (TT), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels were recorded for all patients as well. Only men with pretreatment TT <300 ng/dL were included in the analysis in order to focus our study on men with low TT. Univariate linear regression analysis was performed to determinate the percent change in TT following CC treatment (dependent variable) and pre-treatment E and other variables including age, BMI, FSH, and LH (independent variables). Results:A total of 69 men with TT <300 ng/dL received CC 25 mg every other day. Mean age and BMI were 33.3±7.31 years and 35.4±5 kg/m2 respectively. Median pre-treatment E, TT, FSH, and LH were 18 [11.35-24.6] pg/mL, 226 [156-262] ng/dL, 5.1 [2.98-8.05] mIU/mL, and 4.5 [2.6-6.8] mIU/mL respectively. Post-treatment TT was 389 [263-592] ng/dL and TT% change was 102 [45.51-176.75]. Univariate linear regression showed that pre-treatment E (B=-0.595; R2=0.001; P=0.757) did not significantly predict TT% change. TT% change could be significantly predicted by age in years (B=-7.428; R2=0.057; P=0.048), pre-treatment FSH (B=-8.362; R2=0.068; P=0.041), and pre-treatment LH (B=-20.67; R2=0.096; P=0.027). Conclusions:Pre-treatment E level does not appear to predict treatment response with CC in men with low T.
