RESUMO

STUDY QUESTION: Does the presence of FSHR single-nucleotide polymorphisms (SNPs) affect late follicular phase progesterone and estradiol serum levels in predicted normoresponders treated with rFSH? SUMMARY ANSWER: The presence of FSHR SNPs (rs6165, rs6166, rs1394205) had no clinically significant impact on late follicular phase serum progesterone and estradiol levels in predicted normoresponders undergoing a GnRH antagonist protocol with a fixed daily dose of 150 IU rFSH. WHAT IS KNOWN ALREADY: Previous studies have shown that late follicular phase serum progesterone and estradiol levels are significantly correlated with the magnitude of ovarian response. Several authors have proposed that individual variability in the response to ovarian stimulation (OS) could be explained by variants in FSHR. However, so far, the literature is scarce on the influence of this genetic variability on late follicular phase steroidogenic response. Our aim is to determine whether genetic variants in the FSHR gene could modulate late follicular phase serum progesterone and estradiol levels. STUDY DESIGN, SIZE, DURATION: In this multicenter multinational prospective study conducted from November 2016 to June 2019, 366 patients from Vietnam, Belgium and Spain (166 from Europe and 200 from Asia) underwent OS followed by oocyte retrieval in a GnRH antagonist protocol with a fixed daily dose of 150 IU rFSH. All patients were genotyped for 3 FSHR SNPs (rs6165, rs6166, rs1394205) and had a serum progesterone and estradiol measurement on the day of trigger. PARTICIPANTS/MATERIALS, SETTING, METHODS: Included patients were predicted normal responder women <38 years old undergoing their first or second OS cycle. The prevalence of late follicular phase progesterone elevation (PE), as well as mean serum progesterone and estradiol levels on the day of trigger were compared between the different FSHR SNPs genotypes. PE was defined as >1.50 ng/ml. MAIN RESULTS AND THE ROLE OF CHANCE: The overall prevalence of PE was 15.8% (n = 58). No significant difference was found in the prevalence of PE in Caucasian and Asian patients (17.5% versus 14.5%). Estradiol levels on the day of trigger and the number of retrieved oocytes were significantly higher in patients with PE (4779 ± 6236.2 versus 3261 ± 3974.5 pg/ml, P = 0.003, and 16.1 ± 8.02 versus 13.5 ± 6.66, P = 0.011, respectively). Genetic model analysis, adjusted for patient age, body mass index, number of retrieved oocytes and continent (Asia versus Europe), revealed a similar prevalence of PE in co-dominant, dominant and recessive models for variants FSHR rs6166, rs6165 and rs1394205. No statistically significant difference was observed in the mean late follicular phase progesterone serum levels according to the genotypes of FSHR rs6166 (P = 0.941), rs6165 (P = 0.637) and rs1394205 (P = 0.114) in the bivariate analysis. Also, no difference was found in the genetic model analysis regarding mean late follicular phase progesterone levels across the different genotypes. Genetic model analysis has also revealed no statistically significant difference regarding mean estradiol levels on the day of trigger in co-dominant, dominant and recessive models for variants FSHR rs6166, rs6165 and rs1394205. Haplotype analysis revealed a statistically significant lower estradiol level on the day of trigger for rs6166/rs6165 haplotypes GA, AA and GG when compared to AG (respectively, estimated mean difference (EMD) -441.46 pg/ml (95% CI -442.47; -440.45), EMD -673.46 pg/ml (95% CI -674.26; -672.67) and EMD -582.10 pg/ml (95% CI -584.92; -579.28)). No statistically significant differences were found regarding the prevalence of PE nor late follicular phase progesterone levels according to rs6166/rs6165 haplotypes. LIMITATIONS, REASONS FOR CAUTION: Results refer to a population of predicted normal responders treated with a normal/low fixed dose of 150 IU rFSH throughout the whole OS. Consequently, caution is needed before generalizing our results to all patient categories. WIDER IMPLICATIONS OF THE FINDINGS: Based on our results, FSHR SNPs rs6165, rs6166 and rs1394205 do not have any clinically significant impact neither on late follicular phase serum progesterone nor on estradiol levels in predicted normal responders. These findings add to the controversy in the literature regarding the impact of individual genetic susceptibility in response to OS in this population.

RESUMO

PURPOSE: Few studies explored whether prolonged cryo-storage after vitrification affects embryo competence and perinatal outcomes. This systematic review and meta-analysis aims at highlighting any putative impact of cryo-storage duration on cryo-survival, miscarriage, live birth and major malformations. METHODS: A systematic review was performed using MEDLINE (PubMed), ISI Web of Knowledge, Scopus and Embase databases up to June 2021. Data were combined to obtain a pooled OR, and meta-analysis was conducted using a random effects model. Out of 1,389 screened abstracts, 22 papers were assessed for eligibility, and 5 studies were included (N = 18,047 embryos). Prolonged cryo-storage was defined as > 12 months (N = 3389 embryos). Subgroup analysis was performed for untested vitrified cleavage stage embryos (N = 1739 embryos) and for untested and euploid vitrified blastocysts (N = 13,596 and 2712 embryos, respectively). RESULTS: Survival rate, miscarriage, live birth and major malformation rates were all similar in the two groups. CONCLUSION: These data further support the safety of long-term cryo-storage of human embryos beyond 12 months. This is reassuring for good prognosis patients with surplus embryos, couples seeking a second child from supernumerary embryos and women postponing the transfer for clinical or personal reasons.

RESUMO

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) play complementary roles in follicle development and ovulation via a complex interaction in the hypothalamus, anterior pituitary gland, reproductive organs, and oocytes. Impairment of the production or action of gonadotropins causes relative or absolute LH and FSH deficiency that compromises gametogenesis and gonadal steroid production, thereby reducing fertility. In women, LH and FSH deficiency is a spectrum of conditions with different functional or organic causes that are characterized by low or normal gonadotropin levels and low oestradiol levels. While the causes and effects of reduced LH and FSH production are very well known, the notion of reduced action has received less attention by researchers. Recent evidence shows that molecular characteristics, signalling as well as ageing, and some polymorphisms negatively affect gonadotropin action. These findings have important clinical implications, in particular for medically assisted reproduction in which diminished action determined by the afore-mentioned factors, combined with reduced endogenous gonadotropin production caused by GnRH analogue protocols, may lead to resistance to gonadotropins and, thus, to an unexpected hypo-response to ovarian stimulation. Indeed, the importance of LH and FSH action has been highlighted by the International Committee for Monitoring Assisted Reproduction Technologies (ICMART) in their definition of hypogonadotropic hypogonadism as gonadal failure associated with reduced gametogenesis and gonadal steroid production due to reduced gonadotropin production or action. The aim of this review is to provide an overview of determinants of reduced FSH and LH action that are associated with a reduced response to ovarian stimulation.

RESUMO

OBJECTIVE: To compare the perinatal outcomes of singleton pregnancies resulting from blastocyst- vs cleavage-stage embryo transfer and to assess whether they differ between fresh and frozen embryo transfer cycles. METHODS: A systematic review of the literature was carried out using the Scopus, MEDLINE and ISI Web of Science databases with no time restriction. We included only peer-reviewed articles involving humans, in which perinatal outcomes of singleton pregnancies after blastocyst-stage embryo transfer were compared with those after cleavage-stage embryo transfer. Primary outcomes were preterm birth before 37 weeks and low birth weight (< 2500 g). Secondary outcomes were very preterm birth before 32 weeks, very low birth weight (< 1500 g), small-for-gestational-age (SGA), large-for-gestational-age (LGA), perinatal mortality and congenital anomaly. A meta-analysis was performed using a random-effects model. Three subgroups were evaluated: fresh only, frozen only and fresh plus frozen embryo transfer cycles. RESULTS: From a total of 3928 articles identified, 14 were selected for qualitative/quantitative analysis. Significantly higher incidences of preterm birth < 37 weeks (11 studies, n = 106 629 participants; risk ratio (RR), 1.15 (95% CI, 1.05 - 1.25); P = 0.002) and very preterm birth < 32 weeks (seven studies, n = 103 742; RR, 1.16 (95% CI, 1.02-1.31); P = 0.03) were observed after blastocyst- than after cleavage-stage embryo transfer in fresh cycles. However, the risk of preterm and very preterm birth was similar after blastocyst- and cleavage-stage transfers in frozen and fresh plus frozen cycles. Overall effect size analysis revealed fewer SGA deliveries after blastocyst- compared with cleavage-stage transfer in fresh cycles but a similar number in frozen cycles. Conversely, more LGA deliveries were observed after blastocyst- compared with cleavage-stage transfer in frozen cycles (two studies, n = 39 044; RR, 1.18 (95% CI, 1.09-1.27); P < 0.0001) and no differences between the two groups in fresh cycles (four studies, n = 42 982; RR, 1.14 (95% CI, 0.97-1.35); P = 0.11). There were no differences with respect to low birth weight, very low birth weight or congenital anomalies between blastocyst- and cleavage-stage transfers irrespective of the cryopreservation method employed. Only one study reported a higher incidence of perinatal mortality after blastocyst- vs cleavage-stage embryo transfer in frozen cycles, while no differences were found in fresh cycles. CONCLUSIONS: Our results suggest that cryopreservation of embryos can influence outcome of pregnancy conceived following blastocyst- vs cleavage-stage embryo transfer in terms of preterm birth, very preterm birth, LGA, SGA and perinatal mortality. Caution should be exercised in interpreting these findings given the low level of evidence and wide heterogeneity of the studies. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

RESUMO

Behcet's disease (BD) is a systemic inflammatory disease with a still unclear pathogenesis. Although several inflammatory molecules have been studied, current biomarkers are largely insensitive in BD and unable to predict disease progression and response to treatment. Our primary aim was to explore serum levels of soluble CD40 L (sCD40L), soluble intracellular adhesion molecule (sICAM-1), monocyte chemoattractant protein-1 (MCP-1), myeloperoxidase (MPO), leptin, resistin, osteoprotegerin (OPG), soluble type 1 tumour necrosis factor receptor (sTNFR), interleukin (IL)-6 and serum amyloid A (SAA) serum concentration in a cohort of 27 BD patients. The secondary aim was to evaluate potential correlations between the putative circulating biomarkers, demographic profile of patients, the status of disease activity, the specific organ involvement at the time of sample collection and different therapeutic regimens. Serum concentrations of sTNFR (P = 0·008), leptin (P = 0·0011), sCD40L (P < 0·0001) and IL-6 (P = 0·0154) were significantly higher in BD patients than in HC, while no difference was found in MCP-1, MPO and resistin serum levels. Moreover, we observed significantly higher sTNFR serum concentrations in BD patients presenting inactive disease than HC (P = 0·0108). A correlation between sTNFR and age was also found, with higher levels in patients over 40 years than HC (P = 0·0329). Although further research is warranted to elucidate the role of circulating biomarkers, some of that may contribute to the understanding of the physiopathology processes underlying BD activity and damage as well as to provide useful tools for prognostic purposes and a personalized treatment approach.

RESUMO

BACKGROUND: Gonadotropins are protein hormones which are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function. There is still a lively debate on which type of gonadotropin medication should be used, either human menopausal gonadotropin or recombinant follicle-stimulating hormone. The objective of the study was to perform a systematic review of the recent literature to compare recombinant follicle-stimulating hormone to human menopausal gonadotropin with the aim to assess any differences in terms of efficacy and to provide a cost evaluation based on findings of this systematic review. METHODS: The review was conducted selecting prospective, randomized, controlled trials comparing the two gonadotropin medications from a literature search of several databases. The outcome measure used to evaluate efficacy was the number of oocytes retrieved per cycle. In addition, a cost evaluation was performed based on retrieved efficacy data. RESULTS: The number of oocytes retrieved appeared to be higher for human menopausal gonadotropin in only 2 studies while 10 out of 13 studies showed a higher mean number of oocytes retrieved per cycle for recombinant follicle-stimulating hormone. The results of the cost evaluation provided a similar cost per oocyte for both hormones. CONCLUSIONS: Recombinant follicle-stimulating hormone treatment resulted in a higher oocytes yield per cycle than human menopausal gonadotropin at similar cost per oocyte.

RESUMO

BACKGROUND: Resveratrol is a natural polyphenolic compound present in plants and red wine with many potential health benefits. This compound has various anti-inflammatory and anti-tumor properties and can improve cellular mitochondrial activity. This trial was designed to evaluate the effect on the outcome of IVF of Resveratrol supplementation in women > 35 years with good ovarian reserve (AMH > 1.2 ng/ml). Women were randomized to receive or placebo or Resveratrol (150 mg per day) for three months preceding the ovarian stimulation (OS). All patients were stimulated with a starting dose of recombinant FSH ranging between 150 and 300 IU according to age and ovarian reserve. GnRH antagonist flexible protocol was adopted for pituitary suppression. Triggering was performed with urinary hCG (10.000 IU). RESULTS: The study was conducted between January 2019 and December 2022 with aa total of 37 cases and 33 controls were recruited. No statistically significant differences in the number of oocytes retrieved, biochemical pregnancy, clinical pregnancy and live birth rates were observed between women treated with resveratrol and control group. A statistically significant increase in the follicle output rate (FORT) and follicle-to oocyte index (FOI) was observed in women treated with resveratrol-based nutraceutical (0.92 versus 0.77 [p = 0.02], and 0.77 versus 0.64 [p = 0.006], respectively). CONCLUSIONS: Preliminary results from this study indicate that pre-treatment with resveratrol may improve ovarian sensitivity to exogenous FSH, which in turn may decrease the risk of hypo-response to OS in advanced reproductive age women.

RESUMO

STUDY QUESTION: What is the effect of FSHB-211G>T together with the FSHR 2039 A>G on serum FSH in women? SUMMARY ANSWER: Serum FSH levels are affected by the combination of genetic polymorphisms in FSHR and FSHB. WHAT IS KNOWN ALREADY: The relationship between SNPs of the FSHR gene and serum FSH has not been completely clarified. Genetic variants of the FSHB gene have been associated with variation in gene transcription and serum FSH levels in men. No data have been published on the effect of the FSHB-211G>T in women, alone or in combination with the FSHR 2039 A>G. STUDY DESIGN, SIZE, DURATION: This study was a prospective study including 193 healthy women of reproductive age. PARTICIPANTS/MATERIALS, SETTING, METHODS: Infertile and otherwise healthy eumenorrheic women (n = 193) with normal BMI and serum FSH levels were recruited for the study. In all women early follicular phase FSH and AMH were measured by commercial assays, and antral follicle count was measured by transvaginal ultrasound. Genomic DNA was purified from total peripheral blood and genotyping for the two SNPs was performed. MAIN RESULTS AND THE ROLE OF CHANCE: No significant gradients of increasing or decreasing Day 3 FSH across the FSHR 2039 (AA/AG/GG) and FSHB-211 (GG/GT/TT) genotypes, respectively, were observed. When women were stratified according to the FSHR 2039, and FSHB-211 genotypes a statistically significant reduction of d3 FSH was shown in the group of women with the FSHB-211 GT + TT/FSHR2039 AA genotype compared with the FSHB-211 GG/FSHR2039 GG genotype, hence confirming a possible additive effect of the different SNPs in FSHR and FSHB on regulating serum FSH. LIMITATIONS, REASONS FOR CAUTION: This finding requires an independent confirmation. However, it confirms the relationship between serum FSH and FSHB together with FSHR gene polymorphisms already reported in males. WIDER IMPLICATIONS OF THE FINDINGS: The knowledge of the FSHB/FSHR genotype combination is fundamental for the proper interpretation of serum FSH levels in women of reproductive age. STUDY FUNDING/COMPETING INTERESTS: Merck Serono supported the study in the form of a research grant for the laboratory session. None of the authors have any competing interest to declare.

RESUMO

UNLABELLED: Deficiency of 17ß-hydroxysteroid dehydrogenase type 3 (17ßHSD3), an enzyme converting androstenedione (A) to testosterone (T), is a rare cause of autosomal recessive 46,XY disorder of sexual development (DSD). A 18-years phenotypically female patient from southern Italy presented with primary amenorrhea. She had deep voice, macrocephaly, enlarged and bulbous nasal tip, macrostomia, facial acne, breast asymmetry, hypoplasia of the first finger of right hand, proximal implant of the fifth metatarsus bilaterally as well as an increased muscle mass and hirsutism, with hair distribution on face, neck, chest, abdomen, pubic region and on upper and lower limbs. Genital exam showed thickened labra majora with absence of labra minora and a blind-ending pseudo-vagina with clitoris enlargement. Karyotype analysis showed a male genotype (46,XY). Hormonal evaluation showed decreased T (188 ng/dL-6.5 nmol/L) and increased A (10 ng/mL-34,96 nmol/L), considering male reference ranges, resulting in a decreased T/A ratio (0,186). MRI identified testicles in inguinal regions. Human Chorionic Gonadotropin test showed T/A ratio permanently under 0,8. These evidences were suggestive of a 46,XY DSD due to 17ßHSD3 deficiency. An homozygous mutation (IVS3 -1 G>C or c.326-1G>C) of the 17ßHSD3 gene was discovered. Psychologist identified a well determined female gender identity. It was decided to proceed with gonadectomy and vaginal enlargement by use of dilatators. CONCLUSION: The case described represents a new case of DSD due to 17ßHSD3 deficiency. This patient, raised as a girl, is diagnosed in a very late stage. The identified mutation, previously reported only in Dutch and Brazilian population, is one of 27 presently known mutations of 17ßHSD3 gene and is never reported in Italian population.

RESUMO

The aim of this multicentre, prospective, randomised, investigator blind, controlled clinical trial was to evaluate the clinical efficacy and tolerability of a highly purified human menopausal gonadotrophin (hMG) preparation (Merional-HG) when administered to patients undergoing controlled ovarian stimulation (COS) for in-vitro fertilisation (IVF) procedure enrolled in hospital departments. One hundred fifty-seven patients were randomised in two parallel groups: 78 started COS with Merional-HG and 79 with Menopur. Results of the study showed that both highly purified hMG preparations were equivalent in terms of number of oocytes retrieved (primary endpoint: 8.8 ± 3.9 versus 8.4 ± 3.8, p = 0.54). In the patients treated with Merional-HG, we observed a higher occurrence of mature oocytes (78.3% versus 71.4%, p = 0.005) and a reduced quantity of gonadotrophins administered per cycle (2.556 ± 636 IU versus 2.969 ± 855 IU, p < 0.001). Fertilisation, cleavage, implantation rates and the number of positive ß-human chorionic gonadotrophin (hCG; pregnancy) tests and the clinical pregnancy rate were comparable in the two groups. Both treatments were well tolerated. In conclusion, the results of this study support the efficacy and safety of Merional-HG administered subcutaneously for assisted reproduction techniques. Efficiency of Merional-HG appears to be higher due to reduced quantity of drug used and the higher yield of mature oocytes retrieved.

RESUMO

LH plays a key role in the intermediate-late phases of folliculogenesis. Although ovarian stimulation is efficiently achieved in most cases by the administration of exogenous FSH alone, specific subgroups of women may benefit from LH activity supplementation during ovarian stimulation. Some authors have found improved outcome with LH activity supplementation in advanced reproductive age women. Experience suggests that in about 10-12% of young normogonadotrophic patients treated with a gonadotrophin-releasing hormone agonist (GnRH-a) long protocol plus recombinant FSH human (r-hFSH), a 'steady response' is observed. In this subgroup of women, a higher number of oocytes is retrieved when daily LH activity supplementation is given from stimulation day 8, if compared with the standard FSH dose increase. Another subgroup of patients who may benefit from LH activity supplementation are those at risk for poor ovarian response treated with GnRH antagonist. Recent data demonstrate that in these women, when GnRH is administered in a flexible protocol, the concomitant addition of recombinant human LH improves the number of mature oocytes retrieved, when compared with the standard GnRH-a flare-up protocol. Thus, well calibrated LH administration improves the ovarian outcome in patients >35 years, in those showing an initial abnormal ovarian response to r-hFSH monotherapy, and in 'low prognosis' women treated with GnRH antagonists.

RESUMO

The aim of this observational preliminary trial was to estimate the association between the most common polymorphism of LH (LH-ß variant: v-ßLH), with different profiles of ovarian response to recombinant human FSH (rhFSH). A total of 60 normogonadotrophic patients undergoing a gonadotrophin-releasing hormone analogue long down-regulation protocol followed by stimulation with recombinant human FSH (rhFSH) for IVF/intracytoplasmic sperm injection, and in whom at least five oocytes were retrieved were retrospectively included. On the basis of the total rhFSH consumption, patients were divided into three groups: Group A: 22 women requiring a cumulative dose of rhFSH >3500 IU; Group B: 15 patients requiring 2000-3500 IU; Group C (control): 23 women requiring <2000 IU. The presence of v-ßLH was evaluated using specific immunoassays. Peak oestradiol concentrations were significantly lower in Group A when compared with both groups B (P < 0.05) and C (P < 0.001). Group A had a significantly lower (P < 0.05) number of oocytes retrieved (7.3 ± 1.5, 11.7 ± 2.4 and 14.7 ± 4.1 in the three groups, respectively). Seven carriers (31.8%) of v-ßLH were found in Group A, whereas only one variant (6.7%) was observed in Group B; no variant was detected in Group C. These preliminary results suggest that v-ßLH is more frequent in women with ovarian resistance to rhFSH.

RESUMO

In this prospective study, we evaluated the steroid levels in 111 follicular fluids (FF) collected from 13 women stimulated with FSH monotherapy and 205 FF collected from 28 women stimulated with FSH + LH because of a previous history of hypo-responsiveness to FSH. Steroid levels were measured by HPLC/MS-MS and related to ovarian stimulation protocol, oocyte maturity, fertilization and quality of blastocysts, after individually tracking the fate of all retrieved oocytes. 17-Hydroxy-Progesterone, Androstenedione, Estradiol and Estrone were significantly higher in the FSH + LH protocol. Progesterone, 17-Hydroxy-Progesterone and Estradiol were more expressed in FF yielding a mature oocyte (p < 0.01) in the FSH + LH protocol. FF Progesterone concentration was correlated with the rate of normal fertilization in the FSH protocol. None of the FF steroids measured were associated with blastocyst quality and achievement of pregnancy. Our results indicate that LH supplementation in hypo-responsive women modifies ovarian steroid production, mimicking physiological production better and likely contributing to an improved ovarian response. Employing a correct methodological procedure to evaluate the relationship between FF steroid hormones and assisted reproduction outcomes, our study reveals that some steroids in single follicles may be helpful in predicting oocyte maturity and fertilization.

On the basis of the total rhFSH consumption, patients were divided into three groups: Group A: 22 women requiring a cumulative dose of rhFSH >3500 IU; Group B: 15 patients requiring 2000-3500 IU; Group C (control): 23 women requiring <2000 IU. The presence of v-betaLH was evaluated using specific immunoassays. Peak oestradiol concentrations were significantly lower in Group A when compared with both groups B (P < 0.05) and C (P < 0.001). Group A had a significantly lower (P < 0.05) number of oocytes retrieved (7.3 +/- 1.5, 11.7 +/- 2.4 and 14.7 +/- 4.1 in the three groups, respectively). Seven carriers (31.8%) of v-betaLH were found in Group A, whereas only one variant (6.7%) was observed in Group B; no variant was detected in Group C. These preliminary results suggest that v-betaLH is more frequent in women with ovarian resistance to rhFSH.

RESUMO

OBJECTIVE: The application of an electronic database in clinical practice is used widespread in every field of medicine. The aim of the present study is to illustrate our experience to use a database software for documentation of two of our clinical activities, outpatient hysteroscopy and inpatient gynaecological surgery. PATIENTS AND METHODS: In 2004, we designed two databases, the first one to document surgical procedures in the operating theatre, the second to document outpatient hysteroscopy procedures using FileMaker v.8.5. The data entry interface contains free text fields for patient demographic data and the description of the surgical procedure, supplemented by drop-down lists for items such as clinical findings, procedures, instrumentation, technique, and complications. Copies were filed in the main hospital notes, sent to General Practitioners, and also given to our patients. RESULTS: Since August 2004, we have used our two databases to document 2766 gynaecological operations and 3777 outpatient hysteroscopies. All users particularly liked the dropdown lists as their use greatly reduced the time taken to enter each patient's data. The databases were regularly used to select patients for audit projects and research data collection for prospective studies. CONCLUSIONS: FileMaker is an user-friendly and easily configured software, extremely valuable in everyday clinical work.

RESUMO

OBJECTIVE: The use of gonadotropin-releasing hormone agonist for ovulation triggering has become an intriguing topic in the last few years. As long as adequate luteal phase support is provided, it may be a valuable alternative to standard hCG triggering, associated with a significant reduction in OHSS incidence. Several luteal phase support options have been proposed, but few studies have addressed the issue of the appropriate route for progesterone administration to women triggered with GnRHa. The aim of the study was to evaluate the effect of GnRHa triggering on IVF/ICSI outcomes, using modified luteal phase support with intramuscular progesterone. PATIENTS AND METHODS: A retrospective study was carried out between January 2014 and December 2015, comparing the reproductive outcome in GnRHa triggered women given modified luteal phase support with intramuscular progesterone (Group A) with the outcome in women triggered with standard hCG (Group B) in IVF/ICSI cycles. RESULTS: 200 (Group A n = 100; Group B n = 100) consecutive normoresponder women were included. No differences with respect to Age, BMI, basal FSH, basal Estradiol and infertility diagnosis were observed between groups. Increased numbers of retrieved oocytes (8.1 ± 3.3 versus 6.8 ± 3.5, p = 0.009) and mature oocytes (5.8 ± 2.6 versus 5.1 ± 2.7, p = 0.03) were detected in Group A compared with Group B. Implantation, biochemical pregnancy and ongoing pregnancy rates were similar. CONCLUSIONS: Our findings confirmed that the GnRHa triggering strategy is associated with increased number of oocytes retrieved and of mature oocytes even in normoresponder women. Moreover, in these patients, the use of intramuscular progesterone during luteal phase support achieved satisfactory IVF outcomes.

RESUMO

OBJECTIVE: To evaluate the hormonal profile in three breast cancer patients who underwent controlled ovarian stimulation in the presence of the aromatase inhibitor letrozole. PATIENTS AND METHODS: In IVF University referral center, a case series of three breast cancer patients who underwent controlled ovarian stimulation (COS) with recombinant FSH and letrozole were investigated. Ovulation was induced with hCG (case No. 1) or with GnRH agonist (case No. 2-3). The primary outcome of our study was the detection of progesterone levels in the luteal phase. RESULTS: Very high progesterone values (mean 186.6 ± 43.6 ng/mL) during the luteal phase were recorded in all three cases. CONCLUSIONS: High progesterone levels can be related to the use of letrozole independently of the most commonly used trigger regimen. Although progesterone has long been considered a protective factor against breast cancer, several studies have demonstrated that progesterone could expand a transformation-sensitive stem cell population in the mammary glands. The estrogen negative feedback effect on the hypothalamus-pituitary axis and the disruption of steroid biosynthesis and could represent an intriguing reason behind this phenomenon. Our results highlight the need to evaluate further the increase in progesterone levels in the luteal phase in women with breast cancer undergoing COS with letrozole.

RESUMO

BACKGROUND: Granulosa-cells are able to produce and store leptin, suggesting that this hormone is locally involved in the regulation of follicular growth. In this study, the role of follicular fluid (FF) leptin concentration in predicting oocyte fertilization and embryo quality was evaluated in 35 normogonadotrophic women undergoing controlled ovarian stimulation (COS) for assisted reproductive techniques. MATERIALS AND METHODS: Leptin concentration was measured in 47 consecutively collected FF in which a mature oocyte had been found during the ovum pick-up. Embryos deriving from fertilized oocytes were submitted to quality scoring systems. RESULTS: Mean leptin concentration was significantly higher in FF whose oocytes showed 2 pronuclei (no. 25) when compared with those with no evidence of fertilization (no. 22) at the 16-18 h check (26.0+/-6.1 vs 15.3+/-10.6 ng/ml, respectively, p<0.01). Follicular mean diameters were similar in the two groups (21.4+/-3.4 and 21.0+/-5.1 mm, respectively). Logistic regression analysis identified FF leptin levels as the best predictive parameter for oocyte fertilization (p<0.001). When receiving operating characteristics curve was employed, a FF leptin concentration of 20.25 ng/ml was the most reliable cut-off in predicting fertilization of oocytes. FF with leptin concentrations higher than this value (no. 27) had an oocyte fertilization rate of 85.7%. In contrast, FF levels < or =20.25 ng/ml (no. 20) were associated with a rate of 16.7% (p<0.05). No correlation emerged between FF leptin and the score attributed to 15 valuable embryos at the zygote stage (r=-0.01) and at 48 h after insemination (r=0.1). CONCLUSIONS: FF leptin levels are a better predictor of oocyte fertilization success rates than follicular diameter. These results underline the relevance of FF variables in developing methods for oocyte selection.

RESUMO

Pelvic endometriosis is an immune-related chronic inflammatory disease, characterized by ectopic implants of endometrium in the peritoneal cavity and associated with increased secretion of proinflammatory cytokines and neoangiogenesis. Leptin, the adipocyte-derived hormone, has been shown to have a role in food intake, basal metabolism, and reproductive function. Leptin levels are dynamically regulated, being elevated by inflammatory mediators and reduced by starvation. Leptin itself can influence the proinflammatory immune responses of CD4+ T lymphocytes, and reports have also shown this hormone to be an angiogenic factor in vitro and in vivo. We investigated whether leptin concentrations in serum and peritoneal fluid (PF) differed between 13 patients with different stages of endometriosis and 15 age- and body mass index-matched controls. We found a statistically significant (P < 0.05) increase in leptin levels in serum (30.3 +/- 14.8 ng/mL) and PF (35.9 +/- 17.4 ng/mL) of patients with endometriosis, compared with our control population (serum, 15.6 +/- 8.4; PF, 17.5 +/- 7.2 ng/mL). Regression equations, relating leptin to body mass index, were also significantly different in endometriosis patients, compared with controls. Higher levels of leptin were observed in the earlier stages of endometriosis than advanced-stage disease. These data suggest that the proinflammatory and neoangiogenic actions of leptin may contribute to the pathogenesis of endometriosis.

RESUMO

One of the most frequent consequences of allogeneic haemopoietic stem cell transplantation (allo-SCT) in both males and females is gonadal insufficiency. We report the case of a 27-year-old myelodysplastic male who developed azoospermia after allogeneic transplantation of haemopoietic stem cells from his HLA-identical sister. Post-transplant azoospermia was alternated with intermittent severe oligospermia. The patient had a normal endocrine pattern and evidence of mild chronic graft-versus-host disease (cGVHD). Normal intratesticular spermatogenesis was revealed by bilateral fine needle aspiration (FNA) cytology. Inflammation was evident at semen analysis, but no infection was detected by microbiological examination and sperm culture. These findings, together with the re-appearance of sperm cells at semen analysis after a low-dose immunosuppressive treatment, suggested the presence of cGVHD of the urogenital tract, causing a reversible obstruction of the spermatic tract and cryptozoospermia. This is the first case report documenting a severe impairment of sperm count because of a reversible obstruction of the seminal tract, likely caused by cGVHD, in a long-term survivor of allo-SCT with normal endocrine pattern. An important practical consequence of this case report is the fact that azoospermia was cured using low-dose immunosuppressive therapy, and this allowed us to avoid expensive stimulatory treatments with gonadotrophins, which remain, however, ineffective if the obstruction of spermatic tracts is not removed. A spontaneous uncomplicated pregnancy occurred in the partner of the patient 3 months after the corticosteroid treatment withdrawal.
