Pharmacokinetics and safety profile of a novel progesterone aqueous formulation administered by the s.c. route.

A novel aqueous progesterone formulation was developed. Study I: Three-way cross-over, open-label study in 24 post-menopausal women. Comparison of the pharmacokinetic profiles of a single 100 mg dose of test product administered by subcutaneous (s.c.) and intramuscular (i.m.) injection and an i.m. reference oily product. Study II: Three-way cross-over open-label study of 25, 50 and 100 mg s.c. single doses of the aqueous formulation in 12 post-menopausal women. Study III: Parallel-group, observer-blinded study in 25 fertile women administered multiple s.c. 25 and 50 mg doses of the aqueous formulation once daily for 11 days. Baseline-corrected pharmacokinetic parameters were evaluated. Aqueous formulation (100 mg) was promptly absorbed, achieving progesterone peak serum levels at an earlier time than the reference (1 h vs. 7 h; p < 0.0001). Test and reference were bioequivalent in the extent of exposure: confidence intervals for AUC(0-t) geometric means ratios were within the pre-specified 80-125% limits. Pharmacokinetics was linear over the range of doses studied. Steady state was reached within 4 days of multiple dose treatment. All treatments were well tolerated. Considering the advantages given by the possibility of self-medication, the s.c. aqueous formulation could offer a convenient alternative for patients on assisted reproductive technology treatments.

Small GTPases are involved in sprout formation in human granulosa lutein cells.

INTRODUCTION: The corpus luteum (CL), develops from the ruptured follicle after gonadotropin stimulation. Based on intracellular reorganization of the cytoskeleton an human chorionic gonadotropin (hCG) dependent sprouting and migration of luteinizing granulosa cells (LGCs) and endothelial cells is observed. Rho-GTPases are shown to be key regulators of cytoskeletal restructuring. In the present study we analyzed the role of Rho-GTPases in the sprouting activity of LGCs. METHODS: We used the Rho-GTPase-inhibitors Toxin A and -B and the Cdc42-activator Bradykinin in a LGC-spheroid sprouting assay to determine the effect of these modulators in LGCs. RESULTS: Toxin A and Toxin B reduces sprout formation in LGC spheroids. However, the reduction is less than in hCG treated cells. The usage of Bradykinin demonstrates both, a reduction of sprouts in untreated spheroids and an increase of sprouting in previous hCG treated spheroids. CONCLUSIONS: The presented results let us suggest that small Rho-GTPases may regulate the sprouting activity of LGCs after stimulation by hCG and that this mechanism may play a role in CL formation.

Clinical Efficacy of Follitropin Alfa in GnRH-Antagonist Protocols: A Prospective Observational Phase IV Study on the Use of Biosimilar Follitropin Alfa r-hFSH in Assisted Reproductive Technology in a Routine Care Setting.

BACKGROUND: This phase IV routine care study evaluated ovarian responses when using a biosimilar follitropin alfa r-hFSH (Bemfola®) for controlled ovarian stimulation (COS) in women undergoing assisted reproductive technology (ART) treatment who were pituitary-suppressed with a gonadotrophin-releasing hormone (GnRH) antagonist. METHODS: This multicenter, prospective, non-comparative, non-interventional study (Germany/Austria) was conducted with 885 women (Mean age of 34.0±4.4 years) for whom COS with Bemfola® and GnRH-antagonist for pituitary suppression were applied as part of in vitro fertilization (IVF) treatment with/without intracytoplasmic sperm injection (ICSI) observing routine clinical-practice protocols. Primary endpoint was the number of retrieved cumulus-oocyte-complexes (COCs). RESULTS: Among 986 ART cycles, COS was given for 9.9±1.8 days (First-day r-hFSH dose of 220.7±68.9 IU; mean total dose of 2184.3±837.5 IU). It was revealed that 99.1% of cycles resulted in follicular puncture, with mean of 10.7±6.6 oocytes retrieved. Successful fertilization took place after IVF/ICSI in 93.8% of follicular punctures. Freeze-all was performed in 14.2% of cycles. Fresh embryo transfer was performed in 76.9% of cycles with follicular puncture; mean day of transfer was 3.5±1.3 and average number of transferred embryos was 1.76±0.50. Clinical pregnancy rate was 30.2% of embryo-transfer cycles and 23.4% of started cycles. Sixty-nine reports of ovarian hyperstimulation syndrome (7.0% of started cycles) were documented. CONCLUSION: COS with Bemfola® in GnRH-antagonist IVF/ICSI protocols in a routine care setting led to an appropriate ovarian response allowing oocyte retrieval in 99.1% of initiated cases.

Seminal fluid ribavirin level and functional semen parameters in patients with chronic hepatitis C on antiviral combination therapy.

BACKGROUND & AIMS: Due to the possible teratogenic effect of ribavirin, effective contraception is mandatory during antiviral therapy in patients with chronic hepatitis C (CHC). The aim of this study was to evaluate seminal parameters and ribavirin and HCV-RNA concentrations in seminal fluid and serum prior to and during antiviral treatment. PATIENTS AND METHODS: Fifteen male patients (age: 42+/-9 (years+/-SD)) with CHC treated with pegylated interferon-alpha-2a and ribavirin were investigated. Seminal fluid (sperm concentration, motility, and morphology) was analysed morphologically. HCV-RNA and ribavirin concentration were determined by quantitative PCR and HPLC, respectively. Examinations were carried out at baseline, week 4, and week 12. RESULTS: Ribavirin concentration was higher in seminal fluid than in serum (week 4: 5.2+/-2.5 vs. 2.1+/-0.3; week 12: 4.4+/-1.8 vs. 2.0+/-0.3 (microg/ml, mean+/-SD; p<0.001)). Semen abnormalities were common at baseline (asthenoteratozoospermia: n=6; asthenozoospermia: n=3; teratozoospermia: n=3). Sperm density (BL: 67+/-33x10(6)/ml; week 4: 42+/-25 (p<0.05); week 12: 49+/-33 (n.s.)), percentage of sperm with progressive motility (BL: 40+/-26%; week 4: 27+/-25; week 12: 31+/-20 (n.s.)), and percentage of sperm with normal morphology (BL: 25+/-15; week 4: 20+/-11; week 12: 16+/-9; p<0.05 for both) further decreased during antiviral therapy. HCV-RNA was detectable in the seminal fluid of only two patients prior to antiviral therapy and was undetectable in all patients during combination therapy. CONCLUSION: Semen abnormalities were common in CHC patients, with further impairment during antiviral therapy. Ribavirin concentration was elevated twofold in seminal fluid compared to serum levels, which reinforces the need for contraception during antiviral combination therapy.

Smoking Decreases Endometrial Thickness in IVF/ICSI Patients.

INTRODUCTION: Smoking is a serious problem for the health care system. Many of the compounds identified in cigarette smoke have toxic effects on the fertility of both females and males. The purpose of this study was to determine whether smoking affects clinical factors during IVF/ICSI therapy in a single-center reproductive unit. MATERIAL AND METHODS: In a retrospective study of 200 IVF/ICSI cycles, endometrial thickness and the outcome of IVF/ICSI therapy were analyzed. RESULTS: Endometrial thickness was significantly lower in smoking patients than in non-smoking patients (10.4 ± 1.5 mm vs. 11.6 ± 1.8 mm). Age was significantly higher in women who failed to conceive. The total dose of gonadotropins administered was significantly lower in pregnant patients and the highest pregnancy rate was achieved with an rFSH protocol. BMI and number of cigarettes smoked did not influence treatment outcomes in this study. CONCLUSION: We showed that smoking has a negative effect on endometrial thickness on the day of embryo transfer. This may help to further explain the detrimental influence of tobacco smoke on implantation and pregnancy rates during assisted reproduction therapy.

Effects of tibolone on selectins in postmenopausal women.

OBJECTIVE: The first step in atherosclerosis is characterized by the adherence of lymphocytes and monocytes to cell adhesion molecules expressed by endothelial cells. The precise mechanism by which steroid hormones may be exerting a protective action against atherogenesis remains unclear. Therefore, we wanted to investigate the effect of tibolone on the circulating levels of various selectins in postmenopausal women. METHODS: Thirty healthy postmenopausal women were enrolled in a prospective, randomized, double blind, placebo-controlled outpatient trial. RESULTS: Patients treated with tibolone revealed a significant decrease for the variables sE-selectin, sL-selectin, and sPECAM-1 after 8 weeks of treatment. CONCLUSIONS: By reducing leukocyte adhesion molecule expression on human endothelial cells, tibolone may have the intrinsic potential to exert additional, lipid-independent, cardiovascular protective effects that may explain the clinical benefits of cardiovascular diseases in postmenopausal women.

Comparison of pharmacokinetic and safety profiles between Bemfola(®) and Gonal-f(®) after subcutaneous application.

Recombinant human follicle stimulating hormone (r-hFSH) is effective and safe for controlled ovarian stimulation. Bemfola(®) (Finox AG, Burgdorf, Switzerland), a new biosimilar r-hFSH, has proven comparable non-clinical pharmacological profiles to those of the widely used Gonal-f(®) (Serono Pharma S.p.A., Bari, Italy). The objective of this study was to show that Bemfola(®) yields comparable clinical pharmacokinetic (PK) and safety profiles to Gonal-f(®) in healthy female subjects. In this randomized, Phase I trial conducted in healthy female volunteers (N = 32), a 2-period, balanced 2-treatment crossover design was used. A single subcutaneous dose of 225 IU Bemfola(®) or Gonal-f(®) was administered in each treatment period per sequence. Blood was collected for pharmacokinetic analysis until 10 days after each r-hFSH treatment. For down-regulation of endogenous FSH subjects were given a depot injection with leuprolide acetate prior to the study drug in either sequence. Pharmacokinetic data was available for 23 subjects. No appreciable differences in key PK parameters were detected between the r-hFSH products as per non-compartmental PK analysis [i.e. for Bemfola(®) and Gonal-f(®) respectively AUC0-192 424.90 and 432.75 IU h/L, C max 0.98 and 0.95 IU/L, T max 24.0 h (range 6.0-24.0) and 24.0 h (range 9.0-24.0), t 1/2 43.58 h [standard deviation (SD 14.17)] and 42.58 h (SD 16.47), and K e 0.0075 1/h (SD 0.003) and 0.0077 1/h (SD 0.002)]. Subgroup analysis for estradiol (E2) response was similar for Bemfola(®) and Gonal f(®) (AUC(0--120) p = 0.21 and C max p = 0.82). No major safety issues were identified and no immunogenic reaction to r-hFSH was observed. The results of this study indicate that a single dose of Bemfola(®) exhibits pharmacokinetic and safety profiles comparable to Gonal-f(®) in healthy young women.

Identification of estrogen and progesterone receptor mRNA expression in the conjunctiva of premenopausal women.

PURPOSE: The purpose of the present study was to identify the expression of estrogen and progesterone receptor mRNA and of estrogen and progesterone receptor protein in the conjunctiva of healthy women. METHODS: Specimens of conjunctival tissue of 10 premenopausal women (age range, 13-38 years) were obtained during ophthalmic surgery in patients under general anesthesia. Specimens of approximately 4 mm(2) were taken from superior, nasal, or temporal bulbar conjunctiva adjacent to the bulbus and were immediately deep frozen with liquid nitrogen. Four women underwent strabismus surgery, two had phacoemulsification, and four had vitrectomy. Only three women were taking oral contraceptives. The expression of estrogen receptor (ER)-alpha, ERbeta, and progesterone receptor (PR) mRNA was analyzed by RT-PCR. Western blot analysis on nuclear extracts was performed with the anti-ERalpha mouse monoclonal antibody AB-15, the anti-ERbeta mouse monoclonal antibody 6B12, and the anti-PR mouse monoclonal antibody PgR 636. RESULTS: In two samples, ERalpha, ERbeta, and PR mRNAs were not accessible because of highly degraded RNA. In the remaining eight samples, an appearance rate of 100% was obtained for all three mRNAs. Similarly, an appearance rate of 100% was obtained for ERalpha, ERbeta, and PR protein in nine tissue samples accessible for analysis; one sample could not be analyzed due to a low amount of tissue. CONCLUSIONS: This study confirms the existence of estrogen and progesterone receptors in the human conjunctiva of premenopausal females. Because the proteins of estrogen and progesterone were also found in this study's specimens, the data indicate that the conjunctiva is a target site for sex steroids. Future studies are needed to elucidate the role of these receptors in ocular diseases involving the conjunctiva.

Effects of tibolone on cell adhesion molecules in postmenopausal women.

OBJECTIVE: The first step in atherosclerosis is characterized by the adherence of lymphocytes and monocytes to cell adhesion molecules expressed by endothelial cells. Therefore, we wanted to investigate the effect of tibolone on the circulating levels of various cell adhesion molecules. DESIGN: Thirty postmenopausal women were enrolled in a double-blind, randomized, placebo-controlled outpatient trial. RESULTS: Tibolone led to a significant decrease in soluble intercellular adhesion molecule-1, soluble intercellular adhesion molecule-3, and soluble vascular cell adhesion molecule-1, but had no effect on monocyte chemotactic protein-1. CONCLUSIONS: The direct favorable effects of tibolone on endothelial cells may explain the clinical benefits of this substance in terms of anti-ischemic effects and osteoporosis prevention.

Analysis of an interleukin-6 gene promoter polymorphism in women with endometriosis by pyrosequencing.

Interleukin (IL)-6 has been implicated in the etiology of endometriosis. A single nucleotide polymorphism (SNP) at position -174 in the IL-6 gene promoter appears to influence IL-6 transcription rates in vitro and basal IL-6 levels in vivo. We determined the genotype and the allele frequencies of the -174 IL-6 promoter polymorphism and the corresponding IL-6 serum levels in women with endometriosis. The pyrosequencing technique was used to assess the IL-6 genotypes in 94 women with histologically confirmed endometriosis (study group). A series of 70 healthy women without history of uterine disease served as clinical controls (control group).Allele frequencies for the G allele among women with and without endometriosis were 59.6% and 55.0%, respectively (P =.430; odds ratio [OR] 0.83, 95% confidence interval [CI] 0.53, 1.29). Homozygotes for the protective allele C were present in 17.0% of women with endometriosis and in 18.6% of controls were homozygous for the protective allele C (P =.797; OR 0.90, 95% CI 0.40, 2.02). When patients with various disease manifestations were compared, we found an association between the -174 G allele and chocolate cysts (P =.037). Serum levels of IL-6 were significantly higher in women with endometriosis than in controls (P <.001), with highest levels in women with chocolate cysts. There was no association between serum IL-6 levels and IL-6 genotype. The IL-6 promoter polymorphism -174 G/C does not contribute significantly to overall disease susceptibility but does predispose the carrier to distinct endometriosis with chocolate cysts. A genetically determined high IL-6 response might play a pathogenic role in this disease condition.

The influence of Nos3 polymorphisms on age at menarche and natural menopause.

OBJECTIVE: Deficiency of the gene encoding endothelial nitric oxide synthase, i.e. Nos3, has been reported to be associated with late menarche, reduced ovulation rates, fewer deliveries, and earlier onset of menopause in a mouse model. METHODS: We assessed the Glu298Asp and the T-786C polymorphisms of Nos3 in 87 consecutive healthy postmenopausal women by pyro- and capillary-sequencing, respectively. Results were correlated with age at menarche and natural menopause, number of miscarriages and live births, as well as body mass index (BMI) and smoking habits. RESULTS: Allelic frequencies of the Glu298Asp polymorphism of Nos3 were 121 (69.5%) and 53 (30.5%) for the wild-type G allele and the mutant T allele, respectively. Forty-one women (47.1%) were homozygote wild-type (G/G), 39 (44.9%) were heterozygote (G/T), and 7 (8.0%) were homozygote mutant (T/T). Allelic frequencies of the T-786C polymorphism of Nos3 were 105 (60.6%) and 69 (39.4%) for the wild-type T allele and the mutant C allele, respectively. Thirty-three women (38.0%) were homozygote wild-type (T/T), 39 (45.1%) were heterozygote (T/C), and 15 (16.9%) were homozygote mutant (C/C). Presence of at least one mutant allele of the Glu298Asp or the T-786C polymorphisms of Nos3 were not associated with age at menarche, natural menopause, and number of miscarriages and deliveries. BMI above 27 kg/m2 and smoking were associated with earlier onset of natural menopause (47.8 years versus 50.2 years (P = 0.01) and 46.8 years versus 49.8 years (p = 0.02)). CONCLUSIONS: Our data show that smoking and increased BMI, but not Glu298Asp or the T-786C polymorphisms of Nos3, are associated with an early onset of natural menopause.

Polymorphisms of VEGF and VEGF receptors are associated with the occurrence of ovarian hyperstimulation syndrome (OHSS)-a retrospective case-control study.

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is the most serious complication of IVF/ICSI therapy. The pathophysiology and etiology of the disease is still not fully clarified. METHODS: To assess whether polymorphisms of the VEGF/VEGF-receptor system contribute to the occurrence of ovarian hyperstimulation syndrome (OHSS), we performed a retrospective analysis of 116 OHSS patients, and 124 female controls. The following SNPs were genotyped: Rs2071559 (VEGFR2-604); rs2305948 (VEGFR2-1192); rs1870377 (VEGFR2-1719); rs2010963 (VEGF-405); and rs111458691 (VEGFR1-519). Odds ratios (ORs) were estimated with a 95% confidence interval (CI). Linkage disequilibrium (LD) analysis was performed in the three loci of the VEGFR2 gene. RESULT: We found an overrepresentation of the T allele of the VEGFR1-519 polymorphism in OHSS patients (P = 0.02, OR: 3.62, CI: 1.16 - 11.27). By genotype modeling, we found that polymorphism of VEGFR1-519 and VEGF-405 showed significant differences in patients and controls (p = 0.02, OR: 3.79 CI: 1.98 - 11.97 and p = 0.000005, OR: 0.29, CI: 0.17 - 0.50). LD analysis revealed significant linkage disequilibrium in VEGFR2. CONCLUSION: Polymorphisms in the VEGFR2 gene and in the VEGF gene are associated with the occurrence of OHSS. This strengthens the evidence for an important role of the VEGF/VEGF- receptor system in the occurrence of OHSS.

Decline of semen quality during IVF is not associated with subjective male stress.

The aim of the present study was to assess if semen quality declines during in vitro fertilization (IVF) and whether or not this phenomenon is triggered by chronic male stress. In order to test this hypothesis, we first investigated a retrospective cohort of 155 male IVF patients (testing cohort). Subsequently, we started a prospective cohort study in men undergoing their first IVF and assessed semen quality and subjective male chronic stress using a validated tool, i.e. the Fertility Problem Inventory (FPI) questionnaire. The association between stress and sperm quality decline measured 4-6 weeks before the start of IVF (T1) and at the day of oocyte retrieval (T2) was the primary outcome. Live birth rate, first trimester abortion and rate of poor responders were secondary outcomes. In the testing cohort, mean progressive motility, but not mean sperm density significantly declined. There were 78/154 (51%) men who showed a decline in semen density and 50/154 (32%) men who showed a decline in progressive motility. In the validation cohort, progressive motility declined, whereas, sperm density increased from T1 to T2. Of 78 men, 27 men had increased stress (FPI-score > 146). Sperm density and progressive motility were not significantly different in men with and without stress. However, in the presence of male stress, couples had a higher rate of poor responders, miscarriages and a lower rate of live births. Subjective stress is not associated with a decline in semen quality observed during IVF but may be associated with adverse pregnancy outcome.

A randomized trial comparing the endometrial effects of daily subcutaneous administration of 25 mg and 50 mg progesterone in aqueous preparation.

OBJECTIVE: To study the efficacy of a new P preparation in aqueous solution for subcutaneous injection for inducing the predecidual transformation of the endometrium. DESIGN: Prospective, single-blinded, randomized, parallel pilot trial. SETTING: University-affiliated clinical research center. PATIENT(S): Twenty-five regularly cycling female volunteers. INTERVENTION(S): Volunteers, aged 18-45 years, body mass index 19-25 kg/m(2), whose ovaries were suppressed with a GnRH agonist were estrogenized for 14 or 21 days with the use of transdermal systems delivering 0.1 mg/d E2. After confirming that the endometrial thickness was >7 mm, the women were randomized to 25 mg or 50 mg of subcutaneous P injections daily for 11 days, after which the endometrium was sampled with the use of a Pipelle device. The endometrial biopsies were evaluated by two independent pathologists. Adverse events and subjective tolerance were checked every day by the study investigator. MAIN OUTCOME MEASURE(S): Predecidual changes in endometrial biopsies obtained after 11 days of subcutaneous administration of P. RESULT(S): Of 24 biopsies performed (one dropout), 22 provided tissue for histologic analysis. Evidence of predecidual changes in the endometrial stroma was found in 100% of the cases, with no differences between the two studied doses. CONCLUSION(S): Both doses of the new aqueous P preparation available for subcutaneous administration demonstrated predecidual changes in 100% of the interpretable endometrial biopsies in total absence of endogenous P. This offers good prospect of efficacy in luteal phase support for the lowest dose tested, 25 mg/d, the physiologic amount produced daily by the ovary during the midluteal phase. CLINICAL TRIAL REGISTRATION NUMBER: NCT00377923.

Uterine leiomyoma is associated with a polymorphism in the interleukin 1-beta gene.

PROBLEM: To investigate whether polymorphisms in the interleukin-1beta (IL-1beta) gene are associated with uterine leiomyoma. METHOD OF STUDY: Case-control study in a collective of 131 patients and 280 controls. Genotyping of the IL-1beta-511 and IL-1beta-3954 polymorphism was performed by PCR amplification and subsequent RFLP analysis. RESULTS: A significant difference in the allele frequencies of the IL-1beta-511 C

Effect of leukocytospermia on fertilization and pregnancy rates of artificial reproductive technologies.

The aim of this study was to investigate the fertilization and pregnancy rates of artificial reproductive technologies using semen samples without (<1 x 10(6)/mL) and with (> or =1 x 10(6)/mL) leukocytospermia. The overall fertilization rate was 63.4% (range, 44.4-87.5%) in nonleukocytospermic couples and 64.3% (range, 45.3-100.0%) in leukocytospermic couples, whereas the corresponding pregnancy rates were 34.5% and 50%, respectively. These results show that leukocytospermia may not necessarily have a negative effect on outcome after either in vitro fertilization or intracytoplasmic sperm injection.

Auricular electro-acupuncture as an additional perioperative analgesic method during oocyte aspiration in IVF treatment.

BACKGROUND: The aim of this study was to compare the pain-relieving effect and the subjective well-being between auricular electro-acupuncture (EA) analgesia, auricular acupuncture (A) and conventional analgesia with remifentanil (CO). METHODS: A total of 94 women undergoing IVF were randomized to auricular acupuncture with (EA, n = 32) or without (A, n = 32) continuous 1 Hz auricular stimulation (using a battery-powered miniaturized stimulator, P-Stim) or with adhesive tapes instead of needles and no electrical stimulation (control group, CO, n = 30) at the auricular acupuncture points 29, 55 and 57. All patients received patient-controlled analgesia (PCA) with remifentanil. Pain intensity and psychological well-being were assessed by means of visual analogue scales (VAS); tiredness, nausea and vomiting and analgesic drug consumption were documented. RESULTS: Pain relief and subjective well-being were significantly greater in group EA during and after the procedure as compared with groups A and CO (P < 0.001). The patients were significantly more tired in group CO than in groups A and EA (P < 0.001). Consumption of the opioid remifentanil was significantly lower in group EA, comparable nausea (P < 0.001). CONCLUSION: Auricular EA significantly reduces pain intensity and analgesic consumption of the opioid remifentanil during oocyte aspiration in IVF treatment.

Hormone replacement therapy with tibolone: effects on sexual functioning in postmenopausal women.

OBJECTIVE: Because hormonal changes in postmenopausal women may be accompanied by sexual problems and a worsening of various aspects of libido, the aim of this study was to assess the effect of tibolone (Liviel(R)) on sexual life. METHODS: Postmenopausal first-time users of hormone replacement therapy (HRT) were included in this open, multicenter study. Patients were treated with tibolone 2.5 mg daily for at least 4 months. Both at baseline and after 4 months of treatment, patients were asked to complete two different questionnaires rating the women's subjective assessment of their sexual problems or desires. RESULTS: One hundred and eighty-four women were enrolled to receive HRT with tibolone. Overall, a significant increase in women's satisfaction with their sexual lives and a significant improvement in different aspects of libido was found. CONCLUSION: Tibolone has beneficial effects on several aspects of sexual life in postmenopausal women. These effects may be due to both an increase in genital blood flow and the central estrogenic/androgenic activity.

Successful pregnancy resulting from in-vitro matured oocytes retrieved at laparoscopic surgery in a patient with polycystic ovary syndrome: case report.

Combined laparoscopic retrieval of immature oocytes and ovarian electrocautery represents a new management in patients with polycystic ovary syndrome (PCOS), one of the most prevalent endocrinopathies associated with anovulatory infertility. A 31-year-old para II presented with anovulatory, clomiphene-resistant PCOS, and a 6 year history of infertility. Conventional IVF treatment was abandoned in 1999 when she developed severe ovarian hyperstimulation syndrome (OHSS) following gonadotrophin stimulation. Sixteen oocytes were aspirated from both ovaries and collected in culture tubes containing a maturation medium. A total of three 2-cell embryos were transferred 48 h after ICSI. Two weeks after embryo transfer the urinary pregnancy test was positive and after another 2 weeks an ongoing singleton pregnancy with a fetal heartbeat was confirmed at transvaginal ultrasound examination. The combination of laparoscopy, in-vitro maturation and ICSI may open up new therapeutic strategies, even in patients without PCOS and regular menstrual cycles, undergoing laparoscopy for other causes of infertility such as tubal factors and endometriosis.

Body mass index, follicle-stimulating hormone and their predictive value in in vitro fertilization.

PURPOSE: The objective was to explore whether body mass and day 3 follicle-stimulating hormone have predictive value on odds of pregnancy after in vitro fertilisation. Few studies show that obesity produces a variety of alterations in the reproductive system, and that women with an elevation of day 3 FSH have declining ovarian function. METHODS: The data of one-hundred-seventy-one women who underwent a standard regime of controlled ovarian hyperstimulation was analyzed with particular reference to variations in body mass and hormone levels. RESULTS: By raising BMI and FSH (mIU/mL) by one unit, the odds for pregnancy were decreased by the respective factors 0.84 (95% confidence interval 0.73-0.97) and 0.77 (95% confidence interval 0.59-1.00). CONCLUSIONS: The results demonstrate that for the purpose of raising the odds of pregnancy BMI should be reduced. A low FSH value may cause the same effect. Nontheless, obesity and hormonal function may be independent risk factors for failure in assisted reproduction.
