A study of the cost, accuracy, and benefits of 3-dimensional sonography compared with hysterosalpingography in women with uterine abnormalities.

OBJECTIVES: We conducted a prospective blinded study to evaluate the costs, accuracy, risks, and benefits of 3-dimensional (3D) transvaginal sonography compared to hysterosalpingography. METHODS: A total of 101 women aged 26 to 44 years with evidence of uterine anomalies were enrolled. All participants had routine hysterosalpingography as part of their infertility evaluation as well as 3D transvaginal sonography as part of the study. Surgical findings were used as the standard for final diagnosis. RESULTS: A total of 6 normal uteri and 119 uterine anomalies were classified: 30 congenital uterine anomalies (3 arcuate, 1 unicornuate, 4 bicornuate, 2 didelphys, and 20 septate uteri) and 89 acquired anomalies (38 polyps, 30 fibroids, 17 synechiae, and 4 adenomyosis). Congenital anomalies were correctly identified in 30 of 30 cases by 3D sonography but from 10 to 30 of 30 cases by hysterosalpingography. The detection rates for acquired uterine anomalies were lower for both techniques: 44 to 89 of 89 cases for 3D sonography and 22 to 74 of 89 cases for hysterosalpingography. Only 7 of the 20 septi would have been surgically corrected if patients only had hysterosalpingography. On the contrary, 30 of 30 patients with congenital uterine anomalies, 2 of 4 patients with adenomyosis, and all 6 patients with normal uteri were spared from surgery with diagnoses by 3D sonography. No adverse effects were reported after sonography, and only 6 minor ones were reported after hysterosalpingography. CONCLUSIONS: Three-dimensional transvaginal sonography provides visualization and evaluation of the uterine cavity with similar or better accuracy than standard hysterosalpingography in the office setting, with lower cost and morbidity.

The impact of a gonadotropin-releasing hormone antagonist on gonadotropin ovulation induction cycles in women with polycystic ovary syndrome: a prospective randomized study.

OBJECTIVE: To evaluate the effect of the gonadotropin-releasing hormone antagonist Ganirelix on gonadotropin ovulation induction (OI) in patients with polycystic ovary syndrome (PCOS). DESIGN: Prospective, randomized, controlled study. SETTING: Academic infertility center. PATIENT(S): Ninety-eight anovulatory women with PCOS undergoing 154 gonadotropin OI cycles. INTERVENTION(S): Patients were treated with recombinant FSH alone (group 1) or in conjunction with Ganirelix when the leading follicle was ≥13 mm (group 2) versus from the beginning of stimulation (group 3), followed by IUI. MAIN OUTCOME MEASURE(S): Per cycle clinical pregnancy rate (CPR), live-birth rate (LBR), total gonadotropin dose, days of stimulation, serum LH and peak E2, and premature luteinization rate. RESULT(S): Data are suggestive of improved CPR in group 2 versus group 1 (33% vs. 19%) and LBR (35% vs. 20%) but not significantly different. Premature luteinization was highest in group 1 (21% vs. 1.8% in group 2 and 2.1% in group 3). Group 3 had the highest cancellation rate and cost without improving CPR and LBR. No differences were noted in peak serum E2, total gonadotropin dose, or days of stimulation. CONCLUSION(S): Adding Ganirelix in a flexible protocol to gonadotropin OI cycles in women with PCOS may be beneficial by decreasing premature luteinization.

The effect of age on the expression of apoptosis biomarkers in human spermatozoa.

OBJECTIVE: To evaluate the impact of age on the expression of apoptotic biomarkers in human spermatozoa. DESIGN: Cross sectional, prospective study. SETTING: Academic centers. PATIENT(S): Healthy volunteers with proven fertility, stratified by age (n = 25, range: 20-68 years). INTERVENTION(S): Examination of serum hormone levels and basic semen parameters, and assessment of early (plasma membrane translocation of phosphatidylserine) and late (DNA fragmentation) sperm apoptotic markers by flow cytometry (using Annexin-V binding and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling). MAIN OUTCOME MEASURE(S): Apoptosis markers. RESULT(S): Advancing male age was significantly and positively correlated with Annexin-V binding results. Although not significant, there was a clear trend for increased DNA fragmentation in the older groups. The age threshold for these observations appears to be 40 years. Advancing male age was positively correlated with FSH and sex hormone-binding globulin (SHBG) levels, and negatively correlated with sperm concentration. CONCLUSION(S): Advancing male age is associated with the expression of early apoptotic markers as evidenced by significantly increased plasma membrane translocation of phosphatidylserine, as well as with a more subtle proportion of sperm carrying DNA fragmentation. This study confirmed that male age is also associated with a decline in sperm concentration.

Assessment of ovarian reserve with anti-Müllerian hormone: a comparison of the predictive value of anti-Müllerian hormone, follicle-stimulating hormone, inhibin B, and age.

OBJECTIVE: The objective of this study was to evaluate basal anti-Müllerian hormone as a marker for ovarian responsiveness to fertility treatment. STUDY DESIGN: Frozen basal menstrual cycle day 3 serum samples were evaluated retrospectively for anti-Müllerian hormone, inhibin B, and follicle-stimulating hormone levels in 123 in vitro fertilization cycles (93 patients) and compared with in vitro fertilization records. RESULTS: Anti-Müllerian hormone values correlated the best with the number of retrieved oocytes (r = 0.539; P < .001) relative to age (r = -0.323; P < .01), follicle-stimulating hormone (r = -0.317; P < .01), inhibin B (P > .05), luteinizing hormone (P > .05), and estradiol (r = -0.190; P < .05). Receiver operating characteristic curve analysis demonstrated that, for the prediction of <4 oocytes retrieved, anti-Müllerian hormone had the largest area under the curve (AUC = 0.81; P = .0001) relative to age (r = 0.74; P = .005), follicle-stimulating hormone (0.71; P = .02), inhibin B (0.66; P = .03), and estradiol (0.54; P > .05). Similarly, for the prediction of >or=15 retrieved oocytes, anti-Müllerian hormone had the largest area under the curve (0.80; P = .0001) relative to age (0.63; P = .02), follicle-stimulating hormone (0.64; P = .005), inhibin B (r = 0.57; P > .05), and estradiol (0.58; P > .05). CONCLUSION: Anti-Müllerian hormone correlates better than age, follicle-stimulating hormone, luteinizing hormone, inhibin B, and estradiol with the number of retrieved oocytes. Receiver operating characteristic curves estimated that anti-Müllerian hormone accurately predicts ovarian responsiveness to controlled ovarian stimulation with high sensitivity and specificity.

Caspase activity and apoptotic markers in ejaculated human sperm.

The objectives of this study were to determine if human ejaculated sperm exhibit active caspases and if caspase-dependent apoptosis markers are identifiable. Sperm from fertile donors and infertile patients were examined after gradient separation into leukocyte-free fractions of high and low motility. Sperm were evaluated for motion parameters, morphology, caspase activation, and apoptosis markers including phosphatidylserine (PS) translocation (annexin V binding) and DNA fragmentation (TUNEL). Active caspase-3 was detected by immunofluorescent microscopy in a small proportion of sperm in situ, in fractions of high and low motility sperm of patients and donors, but low motility fractions had significantly higher numbers of positive sperm. Immunoblot analysis detected inactive procaspase-3 (32 kDa) in all fractions of low sperm motility from patients and donors, while active caspase-3 (17 kDa) was only detected by immunoblotting in a limited number of low motility fractions from patients and in even fewer fractions from donors. Caspase enzymatic activity, as measured using the fluorogenic substrate DEVD-afc, was higher in patients than in donors in both low and high motility fractions. Annexin V staining and DNA fragmentation were detected in a proportion of sperm, with a higher frequency in the low motility fractions. A significant positive correlation between in-situ active caspase-3 in the sperm midpiece and DNA fragmentation was observed in the low motility fractions of patients, suggesting that caspase-dependent apoptotic mechanisms could originate in the cytoplasmic droplet or within mitochondria and function in the nucleus. These data suggest that in some ejaculated sperm populations, caspases are present and may function to increase PS translocation and DNA fragmentation.

Effect of different incubation conditions on phosphatidylserine externalization and motion parameters of purified fractions of highly motile human spermatozoa.

The objective of this study was to assess the temporal effects of sperm incubation at body temperature with various amounts of human serum albumin (HSA) on motion parameters and phosphatidylserine externalization, an expression of membrane integrity. Purified sperm populations were prepared by discontinuous gradient separation, incubated at 37 degrees C in 3 different culture conditions (human tubal fluid [HTF] alone, HTF plus 0.3% HSA, and HTF plus 3% HSA) and evaluated at 0, 1, 3, 6, and 24 hours. Annexin V binding was used to monitor membrane translocation of phosphatidylserine and a computer-assisted semen analyzer was used to evaluate motion parameters. All incubation conditions led to a time-dependent, significant decline in sperm motion parameters and an increase in exposure of phosphatidylserine (annexin V+, live cells) to the outer leaflet of the plasma membrane in both patients and donors. Patients had a higher degree of motility loss and externalization of phosphatidylserine than donors. The decline in the percentage of normal cells (annexin V-, live) was greater in HTF alone up to 6 hours, and the decline in the percentages of motile and rapid sperm were greater in HTF alone throughout 24 hours when compared with HSA supplementation. We conclude that prolonged incubation of purified populations of highly motile human spermatozoa at body temperature was associated with significant motility loss and membrane changes as revealed by phosphatidylserine translocation. A higher concentration of HSA resulted in a relative protective effect against such impairments, particularly during the first 6 hours of incubation. Under the experimental conditions tested, significant differences were observed between infertile men and fertile controls.
