Retrospective analysis of treatments with recombinant FSH and recombinant LH versus human menopausal gonadotropin in women with reduced ovarian reserve.

PURPOSES: The aim of this study is to determine whether a clinical advantage is gained with use of LH in combination with FSH or as a component of human menopausal gonadotropin (hMG) to achieve optimal ovarian stimulation. METHODS: In this study, we compared retrospectively two regimens, r-FSH/r-LH and hMG, for the treatment of women with reduced ovarian reserve, identified as subjects with antral follicle count (AFC) < 11 and AMH ≤ 1.1 ng/ml. RESULTS: Overall, the clinical pregnancy per started cycle was higher in the r-FSH/r-LH group (12.5 vs. 8.1%, P < 0.02), while implantation (11.1 vs. 9.5%) and miscarriage rates (29.9 vs. 35.9%) were comparable. Data were further analysed performing separate comparisons in subpopulations with different ranges of AFC, i.e. < 4, 4-6 and 7-10. Major differences between the two regimens were observed in women with AFC < 4. In this subpopulation, not only was the clinical pregnancies per started cycle higher in the r-FSH/r-LH group (10.2 vs. 1.5%, P < 0.01), but also implantation was significantly higher (13.0 vs. 2.8%, P < 0.02). CONCLUSIONS: A r-FSH/r-LH regimen appears to be beneficial for the treatment of women with extremely poor ovarian reserve. It should be considered however that, being retrospective, this study is affected by obvious limitations, such as post-treatment patient selection criteria and absence of randomisation.

Oocyte in vitro maturation in normo-ovulatory women.

OBJECTIVE: To review the scientific literature concerning the application of oocyte in vitro maturation (IVM) as a treatment for normo-ovulatory women. DESIGN: Critical evaluation and comparison of the most relevant clinical studies. SETTING: Public IVF unit. PATIENT(S): Normo-ovulatory women. INTERVENTION(S): Oocyte IVM and cryopreservation. MAIN OUTCOME MEASURE(S): Maturation, fertilization, implantation, and pregnancy rates. RESULT(S): Maturation rates in vitro are suboptimal and influenced by several factors. IVM oocytes fertilize and undergo development in vitro with rates similar to in vivo matured control oocytes. In IVM cycles implantation and pregnancy rates are lower compared with controlled ovarian stimulation treatments, but accurate patient selection can improve IVM clinical outcome. CONCLUSION(S): In normal responders, IVM does not reach success rates similar to conventional ovarian stimulation regimens. However, it represents a milder approach to assisted reproduction treatment and an alternative intervention for specific conditions.

Genetic screening in 2,710 infertile candidate couples for assisted reproductive techniques: results of application of Italian guidelines for the appropriate use of genetic tests.

OBJECTIVE: To report the results of the routine application of Italian guidelines that apply to infertile patient candidates for any assisted reproduction technique (ART). The guidelines recommend performing a karyotype analysis in each couple and the screening test for mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) in one of the two partners. DESIGN: Case series. SETTING: Infertility unit. PATIENT(S): Two thousand seven hundred ten consecutive infertile couple candidates for ART. INTERVENTION(S): Peripheral blood evaluation of karyotype and CFTR gene. MAIN OUTCOME MEASURE(S): Frequency of aberrant karyotype and mutated CFTR gene. RESULT(S): A total of 74 aberrant karyotypes were diagnosed, corresponding to 1.3% (95% confidence interval [CI], 0.9%-1.7%) in women and to 1.5% (95% CI, 1.0%-2.0%) in men. In men, the frequency of chromosomal abnormalities differed according to the treatment group (0.3%, 1.1%, and 2.2% in IUI, IVF, and ICSI, respectively). The same was not observed in women. Excluding the 5T variant, 3.8% of the screened patients showed a mutated CFTR gene (95% CI, 3.1%-4.5%), and the mutation was found in both partners in 0.2% of the couples (95% CI, 0.0-0.4%). CONCLUSION(S): The frequency of aberrant karyotypes is higher in infertile couples than in the general population, whereas the frequency of a mutation of the CFTR gene is similar.

Preventing high-order multiple pregnancies during controlled ovarian hyperstimulation and intrauterine insemination: 3 years' experience using low-dose recombinant follicle-stimulating hormone and gonadotropin-releasing hormone antagonists.

OBJECTIVE: To employ protocols of mild ovarian stimulation to prevent an excessively elevated rate of high-order multiple pregnancies. DESIGN: Case series. SETTING: University hospital. PATIENT(S): Six hundred and twenty one consecutive patients undergoing 1,259 controlled ovarian hyperstimulation and intrauterine insemination cycles. INTERVENTION(S): Patients received 50 IU per day of recombinant follicle-stimulating hormone (FSH) starting the third day of the cycle, then a gonadotropin-releasing hormone (GnRH) antagonist on the day in which a follicle > or =13 mm was visualized. Cycles were canceled if three or more follicles > or =16 mm and/or five or more follicles > or =11 mm were detected. MAIN OUTCOME MEASURE(S): Rate of high-order multiple pregnancies. RESULT(S): The clinical pregnancy rate per initiated cycle was 9.2% (95% confidence interval, 7.5-11.1%). The incidence of twins and high-order multiple pregnancies was 9.5% (95% CI, 5.3-16.2%) and 0 (0.0-3.2%), respectively. CONCLUSION(S): In controlled ovarian hyperstimulation and intrauterine insemination cycles, a protocol of 50 IU of recombinant FSH daily combined with the use of GnRH antagonists and a policy of strict cancellation based on echographic criteria are associated with a satisfactory pregnancy rate per initiated cycle and a low risk of high-order multiple pregnancies.

Health-related quality of life and need for IVF in 1000 Italian infertile couples.

BACKGROUND: A specific and still poorly investigated issue in the field of infertility is represented by the impact that the need for IVF techniques may have on health-related quality of life (HRQoL). METHODS: A total of 1000 consecutive couples (1000 women and 1000 men) were invited to complete the Health Survey Short Form (SF-36) questionnaire separately, prior to initiating their first IVF attempt in our unit. Patients were also invited to report about demographic and clinical characteristics. RESULTS: A total of 1936 (96.8%) agreed to participate. Male SF-36 scores were higher than those reported by women. Duration of infertility and previous IVF attempts significantly influenced HRQoL (P < 0.01). When scores were plotted in relation to the normative source of the Italian general population stratified by gender, corresponding age and geographical area, the subjective health profile did not significantly differ from the normative sample for both women and men. CONCLUSION: The need for IVF did not seem to markedly influence subjective health status. Conversely, duration of infertility and failure to achieve a pregnancy through IVF might have a negative impact.
