The comparative gonadal toxicity following two equally effective and non-cross-resistant regimens (MOPP and ABVD) was prospectively evaluated in 53 males with Hodgkins disease. The median age was 29 yr (range 16-45). MOPP produced azoospermia in 28/29 patients (97%) while ABVD induced oligoazoospermia in 13/24 patients (54%). Follicle-stimulating hormone levels were consistently and significantly increased after MOPP while their median value remained within normal range after ABVD. Sperm count was repeated in 34 patients. Recovery of spermatogenesis occurred in 3/21 cases treated with MOPP and in all 13 cases given ABVD. Present findings confirm that the two alkylating agents, mechlorethamine and procarbazine, included in the MOPP regimen cause sterility in most patients while the drugs included in ABVD are not associated with permanent gonadal dysfunction.

BACKGROUND An efficient method for cryopreservation of human oocytes may offer solutions to legal and ethical problems in routine infertility programs and may also be used for fertility preservation for medical and social reasons. METHODS We conducted an observational longitudinal cohort multicentric study to investigate the efficacy and reproducibility of oocyte cryopreservation outcomes in IVF/ICSI cycles. Moreover, the effects of patient and cycle characteristics on the delivery rate (DR) were analyzed. RESULTS In 486 cycles performed in 450 couples, 2721 oocytes were warmed and 2304 of them survived cryopreservation (84.7%). Of the 2182 oocytes subjected to ICSI, the rates of fertilization and development to top-quality embryos were 75.2 and 48.1%, respectively. A total of 128 deliveries were obtained (26.3% per cycle and 29.4% per transfer) for 450 patients (28.4%) and 147 babies were live born from 929 embryos transferred (15.8%). The forward logistic regression analysis on a per patient basis showed that female age [odds ratio (OR): 0.93, 95% confidence interval (CI): 0.88-0.98], number of vitrified oocytes (OR: 1.08, 95% CI: 1.01-1.17) and the day of transfer (OR: 1.97, 95% CI: 1.14-3.42) influenced DR. By recursive partitioning analysis, it can be estimated that more than eight oocytes vitrified are required to improve the outcome (22.6 versus 46.4% DR, respectively). When fewer oocytes are available in women aged >38 years, results are dramatically reduced (12.6 versus 27.5% DR, respectively). Conversely, when >8 oocytes are available, blastocyst culture represents the most efficient policy (62.1% DR; data from one center only). CONCLUSIONS Oocyte vitrification is an efficient and reliable approach, with consistent results between centers and predictable DRs. It should be applied routinely for various indications. A predictive model is proposed to help patient counselling and selection.

At present, oocyte selection is mainly based upon morphological criteria but it is generally acknowledged that its reliability requires further improvement. The aim of this study was to determine whether transcript levels in cumulus cells can provide a useful marker of oocyte developmental competence in vitro. A retrospective study was performed on cumulus cells isolated from 90 oocytes retrieved from 45 patients. Upon fertilization, 35 oocytes originated good-quality embryos and 36 developed into poor-quality embryos, whereas 19 failed to be fertilized. Semi-quantitative measurement of hyaluronic acid synthase 2 (HAS2), gremlin1 (GREM1), and pentraxin 3 (PTX3) mRNAs was performed and data for all genes were obtained from all the samples. Cumulus cells isolated from oocytes that originated high-quality embryos on day 3 of culture had HAS2 and GREM1 transcript levels higher than those detected in cells from oocytes that did not fertilize or developed into poor-quality embryos. No differences were observed in PTX3 levels. Results indicate that the measurement of HAS2 and GREM1 levels in cumulus cells would reliably complement the morphological evaluation providing a useful tool for selecting oocytes with greater chances to be fertilized and develop in vitro.

BACKGROUND The influence of previous conservative surgery for endometriomas on IVF-ICSI outcome is debated. Conflicting information emerging from the literature may be consequent to the fact that endometriomas are mostly monolateral. The contralateral intact ovary may adequately supply for the reduced function of the affected one. To clarify this point, we assess IVF-ICSI outcome in women operated on for bilateral endometriomas. METHODS Women selected for IVF-ICSI cycles who previously underwent bilateral endometriomas cystectomy were matched (1:2) for age and study period with patients who did not undergo prior ovarian surgery. RESULTS Sixty-eight cases and 136 controls were recruited. Women operated on for bilateral endometriotic ovarian cysts had a higher withdrawal rate for poor response (P < 0.001). In these patients, despite the use of higher doses of gonadotrophins, the number of follicles (P = 0.006), oocytes retrieved (P = 0.024) and embryos obtained (P = 0.024) were significantly lower. The clinical pregnancy rate per started cycle in cases and controls was 7% and 19% (P = 0.037) and the delivery rate per started cycle was 4% and 17%, respectively (P = 0.013). CONCLUSIONS IVF outcome is significantly impaired in women operated on for bilateral ovarian endometriomas.

Over a 7-year period, semen analysis was performed in 92 male patients with Hodgkins disease prior to therapy. In 67% of patients semen revealed a decreased chance for fertility (i.e. oligozoospermia, asthenozoospermia and/or teratozoospermia). The mean basal levels of follicle-stimulating hormone (FSH), luteinising hormone, testosterone and prolactin were in the normal range. In 77 patients in complete remission after alternating MOPP/ABVD (mechlorethamine, vincristine, procarbazine, prednisone; doxorubicin, bleomycin, vinblastine, dacarbazine), testicular function was assessed. 87% of patients were azoospermic, 9% had semen abnormalities and only 4% were normospermic. Recovery of spermatogenesis was documented in only 17 of 42 (40%) reassessed patients after a median time of 27 months and was generally not affected by pretreatment sperm quality. After chemotherapy, the mean value of FSH [20.45 (S.E. 1.7) mUI/ml] was significantly superior compared with that of the mean pretreatment values. No difference was documented in the mean testosterone and prolactin values tested before and after treatment. Our findings indicate that, of patients with Hodgkins disease, about half are affected by hypogonadism before starting chemotherapy. By utilising alternating MOPP/ABVD, persistent testicular dysfunction was documented in half of the patients.

BACKGROUND There is growing and consistent evidence showing that ovarian reserve is affected following surgical excision of ovarian endometriomas. Of particular concern is the risk of severe ovarian damage leading to unresponsiveness to ovarian hyperstimulation. In this study, we aimed to determine the rate of this complication. METHODS Ninety-three women underwent surgery for monolateral endometriomas were recruited. Patients who underwent IVF were selected and, in all cases, follicular growth was monitored by serial transvaginal ultrasonography. The main outcome measure was the rate of ovaries remaining silent when stimulated after surgery for endometriomas. RESULTS Absence of follicular growth was observed in 12 operated ovaries although this event never occurred in the contralateral gonad (P < 0.001). The frequency (95% confidence interval) of severe ovarian damage following surgery was 13% (7-21%). CONCLUSIONS Severe ovarian damage, occurring in gonads operated on for ovarian endometriomas, is not a rare event.

STUDY QUESTION Do endometriotic ovarian cysts influence the rate of spontaneous ovulation? SUMMARY ANSWER Endometriotic cysts, no matter what their volume, do not influence the rate of spontaneous ovulation in the affected ovary. WHAT IS KNOWN ALREADY Endometriotic ovarian cysts may negatively affect spontaneous ovulation in the affected ovary. STUDY DESIGN, SIZE, DURATION This was a prospective observational study performed between September 2009 and June 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS This study included women of reproductive age with regular menstrual cycles and unilateral ovarian endometriomas (diameter ≥20 mm) desiring to conceive. Exclusion criteria were: hormonal therapies in the 3 months prior to study entry and previous adnexal surgery. Patients underwent serial transvaginal ultrasound to assess the side of ovulation (for up to six cycles). MAIN RESULTS AND THE ROLE OF CHANCE Ovulation was monitored in 1199 cycles in 244 women (age, mean ± SD, 34.3 ± 4.9 years). 55.3% of the patients had left endometriomas and 44.7% had right endometriomas (P = 0.024). The mean (±SD) diameter of the endometriomas was 5.3 cm (±1.7 cm). Ultrasonographically documented ovulation occurred in 596 cycles in the healthy ovary (49.7%; 95% CI, 46.8-52.6%) and in 603 cycles in the affected ovary (50.3%; 95% CI, 47.1-53.2%; P = 0.919). This observation was confirmed in patients with diameter of the cyst ≥4 cm (n = 166) and in those with diameter of the cyst ≥6 cm (n = 45). One hundred and five patients spontaneously conceived (43.0%; 95% CI, 36.7-49.5%). LIMITATIONS, REASON FOR CAUTION The high pregnancy rate reported in this study was observed in a selected population of women with endometriomas and cannot be extrapolated to all patients with endometriosis. WIDER IMPLICATIONS OF THE FINDINGS Since ovarian endometriomas do not impair spontaneous ovulation, the impact on fertility of surgical excision of ovarian endometriomas should be further investigated.

Semen cryostorage remains the only proven method to preserve fertility in men with cancer. However, the necessity and the justification of banking spermatozoa have been questioned because it has been reported that only a small percentage of patients are referred for assisted reproductive technologies using frozen semen.

Objective To assess the reliability of the most widely used clinical methods for predicting or confirming ovulation. Methods We monitored spontaneous cycles in 101 infertile women using basal body temperature (BBT), transvaginal ultrasound, a urinary stick system for LH surge, and three serum progesterone measurements in the midluteal phase. Transvaginal ultrasound monitoring was standard for ovulation detection and sensitivity. We calculated specificity and accuracy of each method compared with that standard. Results Follicular development and ultrasound evidence of ovulation were confirmed in 97 of 101 cycles (96%). Urinary LH surge preceded follicular rupture assessed by ultrasonography in all cycles and showed concordance with ultrasound-evidenced ovulation in 98 of 101 cases. The timing of BBT nadir had wide variability, and BBT and ultrasonography agreed in a similar percentage of cases (74%). Midluteal serum progesterone assessments showed ovulatory values in 93 subjects, and ovulation was concordant with ultrasonography in 90 subjects. Conclusion Urinary LH was accurate in predicting ovulation with ultrasonography as the standard for detection, but time varied widely. The nadir of BBT predicted ovulation poorly. The BBT chart was less accurate for confirming ovulation, whereas a single serum progesterone assessment in midluteal phase seemed as effective as repeated serum progesterone measures.

OBJECTIVE To investigate the effectiveness of double IUI and to determine the optimal timing of IUI in relation to hCG administration. DESIGN Prospective randomized study. SETTING Infertility Center, Department of Obstetrics and Gynecology, University of Milan. PATIENT(S) Patients with male factor and unexplained infertility undergoing controlled ovarian hyperstimulation (COH) and IUI. INTERVENTION(S) After COH with clomiphene citrate and gonadotropins, patients were randomly assigned to one of the following groups: group A received a single IUI 34 hours after hCG administration, group B received a double IUI 12 hours and 34 hours after hCG administration, and group C received a double IUI 34 hours and 60 hours after hCG administration. MAIN OUTCOME MEASURE(S) Number of follicles > 15 mm in diameter on the day of hCG administration, number of motile spermatozoa inseminated, clinical pregnancy rate. RESULT(S) Two hundred seventy-three patients underwent 449 treatment cycles: 90 patients were treated for 156 cycles in group A, 92 patients for 144 cycles in group B, and 91 patients for 149 cycles in group C. The overall pregnancies rates for groups A, B, and C were 13 (14.4% per patient and 8.3% per cycle), 28 (30.4% per patient and 19.4% per cycle), and 10 (10.9% per patient and 6.7% per cycle), respectively. There was a statistically significant difference between group B and groups A and C. CONCLUSION(S) Our data indicate that two IUIs performed 12 hours and 34 hours after hCG administration is the most cost-effective regimen for women undergoing COH cycles with clomiphene citrate and gonadotropins. Although the second insemination adds up to a slightly higher cost, it significantly increases the chance of pregnancy.
