RESUMO

Commercial hMG drugs are marketed for the treatment of infertility and consist of highly purified hormones acting on receptors expressed in target gonadal cells. Menopur® and Meriofert® are combined preparation of FSH and hCG and are compared in vitro herein. To this purpose, the molecular composition of the two drugs was analyzed by immunoassay. The formation of FSH receptor and LH/hCG receptor (FSHR; LHCGR) heteromer, intracellular Ca2+ and cAMP activation, ß-arrestin 2 recruitment and the synthesis of progesterone and estradiol were evaluated in transfected HEK293 and human primary granulosa lutein cells treated by drugs administered within the pg-mg/ml concentration range. Molecular characterization revealed that Meriofert® has a higher FSH:hCG ratio than Menopur® which, in turn, displays the presence of LH molecules. While both drugs induced similar FSHR-LHCGR heteromeric formations and intracellular Ca2+ increase, Meriofert® had a higher potency than Menopur® in inducing a cAMP increase. Moreover, Meriofert® revealed a higher potency than Menopur® in recruiting ß-arrestin 2, likely due to different FSH content modulating the tridimensional structure of FSHR-LHCGR-ß-arrestin 2 complexes, as evidenced by a decrease in bioluminescence resonance energy transfer signal. This drug-specific activation of intracellular signaling pathways is consistent with the molecular composition of these preparations and impacts downstream progesterone and estradiol production, with Menopur® more potent than Meriofert® in inducing the synthesis of both the steroids. These findings are suggestive of distinct in-vivo activities of these preparations, but require cautious interpretation and further validation from clinical studies.

RESUMO

BACKGROUND: In the absence of international guidelines indicating the usage of vitrification rather than slow-freezing, the study aim was to analyze a large cohort of slow-frozen/thawed embryos to produce a rationale supporting the standardization of IVF cryopreservation policy. METHODS: This retrospective analysis included 4779 cleavage stage embryos cryopreserved by slow-freezing/thawing from September 2009 to April 2017 at a single Center. Biological and clinical outcomes of three different commercial kits adopted sequentially, i.e. Vitrolife Cleave Kit® from Vitrolife (kit 1) vs. K-SICS-5000 Kit® and K-SITS-5000 Kit® from Cook Medical (kit 2) and Freeze/Thaw 1™ Kit® from Vitrolife (kit 3) were collected and compared in the light of cryoprotectants composition. RESULTS: Kit 3 compared to kit 1 and kit 2 showed significantly (P < 0.001) higher embryo survival (79.9% vs. 75.6 and 68.1%, respectively) and frozen embryo replacement (91.5% vs. 86.5 and 83.3%, respectively) rates, and significantly (P < 0.001) lower blastomere degeneration rate (41.5% vs. 43.6 and 52.4%, respectively). No significant difference for clinical outcomes was observed among kits. Only a slight positive trend was observed for kit 3 vs. kit 1 and kit 2 on delivery rate per thawing cycle (7.12% vs. 4.19 and 4.51%, respectively; P < 0.058) and live birth rate (3.07% vs. 2.59 and 1.93%, respectively, P < 0.069). Thawing solutions of kit 3 were similar to those of any warming protocol. CONCLUSIONS: A defined concentration of extracellular cryoprotectants in thawing/warming solutions had a beneficial effect on the embryo cryosurvival rate. Results could provide the rationale for the adoption of a single standardized warming protocol.

RESUMO

Objective To investigate whether different antenatal care models could account for differences in operative delivery rates and adverse neonatal outcomes among low-risk pregnant women, and to identify independent variables associated with delivery modes and adverse neonatal outcomes. Study design Retrospective cohort from a single center of singleton, term, live births between January 2012 and June 2014. Rates of cesarean deliveries, operative vaginal deliveries, and neonatal morbidities were analyzed among women followed by private obstetrician-gynecologists versus national health system providers (certified nurse midwifes supervised by obstetrician-gynecologists), and adjusted for potential confounders. Results Among the 2,831 women in our cohort, obstetric and neonatal outcomes were independent of obstetric providers. After we controlled for confounders, private patients having more than four antenatal ultrasound examinations were more likely to undergo cesarean delivery than public patients with four or fewer sonographic assessments (five to eight prenatal scans: relative risk ratio, 3.3; 95% confidence interval [CI] 1.4-8; nine or more prenatal scans: relative risk ratio, 4.1; 95% CI 1.2-14). Conclusions Multiple prenatal ultrasound examinations in low-risk obstetric populations appear to be an independent and potentially modifiable risk factor for cesarean deliveries.

RESUMO

BACKGROUND: Intracytoplasmic morphologically selected sperm injection (IMSI) is still proposed and employed in the clinical practice to improve the reproductive outcome in infertile couples scheduled for conventional intracytoplasmic sperm injection (cICSI). The aim of the current randomized controlled trial (RCT) was to test the hypothesis that IMSI gives a better live birth delivery rate than cICSI. METHODS: Infertile couples scheduled for their first cICSI cycle for male factor were allocated using a simple randomization procedure. All available biological and clinical data were recorded and analyzed in a triple-blind fashion. RESULTS: Our final analysis involved the first 121 patients (48 and 73 subjects for IMSI and cICSI arm, respectively) because the trial was stopped prematurely on the advice of the data safety and monitoring Committee because of concerns about IMSI efficacy at the first interim analysis. No significant difference between arms was detected in rates of clinical pregnancy per embryo transferred [11/34 (32.3%) vs. 15/64 (23.4%); odds ratio (OR) 1.56, 95% (confidence interval) CI 0.62-3.93, P = 0.343] and of live birth delivery [9/48 (18.8%) vs. 11/73 (15.1%); OR 1.30, 95%CI 0.49-3.42, P = 0.594). CONCLUSION: Current data did not support the routine use of IMSI in the clinical practice for improving cICSI results in unselected infertile couples with male factor.

RESUMO

Myomectomy is the most frequent reproductive surgery to preserve, improve fertility, or both. The present study was designed to assess the safety and efficacy of minilaparotomy for myomectomy through a systematic review of randomized and non-randomized controlled trials with a meta-analysis. All available studies comparing minilaparotomy myomectomy with laparotomy, other minimally invasive surgeries, or both, were included. Available surgical and reproductive data were extrapolated, and a qualitative and quantitative analysis was carried out. Fourteen studies were included in the final analysis for an overall sample of 2151 patients. A total of 1139 patients were treated with minilaparotomy, whereas 239 and 773 patients were treated, respectively, with the laparotomy or laparoscopy. Only two studies comparing minilaparotomy with laparoscopy assessed the reproductive outcomes, and their data synthesis did not demonstrate significant difference between the two surgical techniques. Specific surgical end-points differed significantly between minilaparotomy and laparotomy or laparoscopy, even if those differences were not clinically relevant. In conclusion, current data do not permit a definite conclusion to be drawn. Further studies are needed to clarify the risk-benefit ratio of the minilaparotomy compared with the other minimally invasive surgical procedures for myomectomy to provide clinical recommendations with strong scientific evidence.

RESUMO

The current systematic review with meta-analysis of randomized controlled trials (RCTs) was aimed to evaluate the effects of metformin on reproductive outcomes in patients with polycystic ovary syndrome (PCOS) who receive gonadotropins for ovulation induction. After systematic review of electronic databases and websites for registration of RCTs, a total of 7 RCTs reporting data on 1023 cycles were included in the final analysis. Descriptive data showed an overall low studies' quality due to unclear sequence generation and allocation concealment, lack of blinding procedure, incomplete outcome data and several biases and/or confounders. Data synthesis showed that metformin improved live-birth (odds ratio [OR] = 1.94, 95% confidence interval [CI] 1.10 to 3.44; P = 0.020) and pregnancy (OR = 2.25, 95% CI 1.50 to 3.38; P < 0.0001) rates, without significant heterogeneity across the studies (P = 0.230, estimation of inconsistency = 30%; and P = 0.710, estimation of inconsistency = 0%, respectively, for live-birth and pregnancy rates). A significant reduction of cancellation rate was observed after metformin administration (OR = 0.41, 95% CI 0.24 to 0.72, P = 0.002) without significant heterogeneity across the studies (P = 0.500, estimation of inconsistency = 0%). Metformin administration influenced or did not influence other secondary endpoints assessed with a significant heterogeneity. In conclusion, metformin administration increases the live-birth and pregnancy rate in PCOS patients who receive gonadotropins for ovulation induction. Further well designed, blinded, placebo-controlled, and adequately powered RCTs are need to confirm that metanalytic results.

RESUMO

This study evaluated the impact of different phenotypes of polycystic ovary syndrome (PCOS) on early trophoblast invasion and placentation. Pregnant patients with different PCOS phenotypes and healthy pregnant women, matched for age and body mass index, were enrolled. Histological analysis of trophoblastic and decidual tissue and macroscopic and microscopic assessment of the placentas were performed. Implantation-site vessels with endovascular trophoblast differed significantly among PCOS phenotypes. Placental weight, thickness, density and fetal-placental weight ratio were significantly different in the full-blown and non-polycystic ovary (PCO) phenotypes versus the ovulatory and non-hyperandrogenic phenotypes. The incidence of macroscopic placental lesions was only significantly different between controls and the full-blown and non-PCO phenotypes. The overall incidence of microscopic placental lesions was significantly different among PCOS phenotypes and was significantly higher in the full-blown and non-PCO phenotypes than in the ovulatory and non-hyperandrogenic phenotypes. The rates of chorionic villitis and intervillositis were significantly higher in full-blown and non-PCO phenotypes than in ovulatory and non-hyperandrogenic phenotypes. In conclusion, alterations in early trophoblast invasion and placentation observed in PCOS vary widely according to phenotype.

RESUMO

This study assessed the relationship between regular physical activity and reproductive performance in obese infertile patients who receive assisted reproduction cycles with stable bodyweight. A total of 216 obese infertile women at their first fresh assisted reproduction attempt with stable body mass index (BMI) and available data on their physical activity carried out up to the beginning of the treatment cycle were enrolled in this observational cohort study. Clinical and biological data were recorded and analysed. There were 41 obese patients who did regular physical activity and 175 obese controls who did not. Total pregnancies (16/41, 39.0% versus 28/175, 16.0%, respectively; P = 0.002) and live births (10/41, 24.4% versus 13/175, 7.4%, respectively; P = 0.004) were significantly higher in patients who did physical activity regularly compared with those who did not. After adjusting for confounders, in obese infertile patients who did physical activity regularly, the relative risks for a clinical pregnancy and live birth were 3.22 (95% CI 1.53-6.78; P = 0.002) and 3.71 (95% CI 1.51-9.11; P = 0.004), respectively. In conclusion, regular physical activity carried out before a assisted reproduction cycle is significantly related with improved reproductive performance in obese infertile patients, irrespective of bodyweight loss. Body weight loss improves not only spontaneous pregnancy rates but also those of assisted reproductive techniques (ARTs). Moreover, almost all studies refer to body weight loss due to lifestyle intervention programs consisting in hypocaloric diet and increased physical activity. Instead, very little is known about the specific effects of physical activity alone on human reproduction. Based on these considerations, we designed the present study to assess the relationship between regular physical activity and reproductive outcome in infertile obese patients who receive ARTs. Two-hundred-sixteen obese infertile women with stable body mass index (BMI) and at their first fresh ART attempt were enrolled, and clinical and biological data were recorded and analyzed. Our results demonstrate that the chances to obtain a pregnancy and a baby are 3-fold higher in obese infertile patients who does physical activity regularly in comparison with those who does not, suggesting that regular physical activity before ART cycles improves the reproductive performance in obese women irrespective to body weight loss.

RESUMO

BACKGROUND: Data on patients with endometrial cancer converted to laparotomy are totally lacking. The aim of the present study was to evaluate surgical and oncological outcomes in patients with endometrial cancer scheduled for laparoscopic staging but converted to laparotomy. METHODS: Data of consecutive patients who had undergone surgery for staging endometrial cancer in seven Italian centers were reviewed. Patients' characteristics and surgical and oncological data were noted and analyzed according to surgery, i.e. laparotomy, laparoscopy, and laparoscopy converted to laparotomy. RESULTS: Seventy-one out of 512 (13.9 %) patients scheduled to laparoscopy were converted to laparotomy for reasons related to anesthesiology [38/71 (53.5 %)] or surgery [33/71 (46.5 %)]. The conversion rate varied among stages [41/460 (8.9 %), 13/27 (48.1 %), 17/25 (68.0 %) in patients with stage I, II, and endometrial cancers, respectively]. Significant (P < 0.05) differences among groups were detected in patients' age, body mass index and previous pelvic surgery, and in the distribution of stages and histotype of endometrial cancers. The Kaplan-Meier procedure showed that the cumulative probability of first recurrence (P = 0.089, 0.590 and 0.084 for stage I, II and III, respectively) and of death (P = 0.108, 0.567 and 0.372 for stage I, II and III, respectively) categorized by stages did not attain statistical significance by log-rank testing after correction for confounding factors. CONCLUSIONS: The surgical and oncological outcomes of converted patients are no different from those of patients staged successfully with laparoscopy or with laparotomy. The conversion to laparotomy should be not considered per se a complication.

RESUMO

INTRODUCTION AND HYPOTHESIS: Studies have observed a significant heterogeneity in efficacy data for single-incision minislings (SIMS) as surgical treatment for female urinary incontinence (UI). Our study aim was to test the hypothesis that different vaginal kits for SIMS have different long-term outcomes. METHODS: One hundred and twenty women with stress (SUI) or mixed (MUI) UI were enrolled in a multicenter randomized clinical trial (registration number NCT00751088) and treated with three different SIMS (Ajust, MiniArc, or TVT Secur System). Duration of follow-up was at least 24 months from surgery. The primary outcome was the subjective cure rate at 24 months from surgery; secondary outcomes were rates of total failure and reoperations for UI. RESULTS: At study end, no difference was detected between groups in terms of total subjective cure rate [21 (52.5%) vs. 26 (65.0%) vs. 21 (52.5%), in Ajust, MiniArc, and TVT Secur System group, respectively; P = 0.412] or in terms of total failure rate [24 (60.0%) vs. 22 (55.0 %) vs. 27 (67.5 %), in Ajust, MiniArc, and TVT Secur System group, respectively; P = 0.432]. The proportion of patients who received a second surgery for UI was also not significantly different between groups [13 (32.5%) vs. 10 (25.0%) vs. 13 (32.5%), in Ajust, MiniArc, and TVT Secur System, respectively; P = 0.831]. CONCLUSION: The long-term efficacy of SIMS does not differ between the vaginal kits examined.

RESUMO

The management of oligo-amenorrhea in adolescent patients with polycystic ovary syndrome (PCOS) represents an important and difficult challenge. Metformin and/or oral contraceptives (OCs) are different strategies widely proposed in these patients. The objective of the current review was to provide an overview on the use of metformin and/or OCs for the management of oligo-amenorrhea in adolescents with PCOS underlining their potential risks and benefits in order to help the clinician to choose the best patients' tailored treatment.

RESUMO

STUDY OBJECTIVE: To compare single-incision mini-slings (SIMSs) and retropubic tension-free vaginal tape (r-TVT) in terms of the long-term efficacy and safety for the treatment of female stress (SUI) or mixed urinary incontinence (MUI). DESIGN: Prospective multicenter cohort trial (registration number NCT00751088) (Canadian Task Force II). SETTINGS: Department of Obstetrics and Gynecology, Italy. PATIENTS: Two hundred-forty women with SUI/MUI. INTERVENTIONS: SIMS or r-TVT. MEASUREMENTS AND MAIN RESULTS: The operative time and the use of analgesic tablets were significantly (p < .001) higher and lower, respectively, in the r-TVT group versus the SIMS group. After 24 months of follow-up, no difference between the study arms was observed in terms of the complication rate (30/120 [25%] vs 19/120 [15.8%] for the r-TVT and SIMS arms, respectively; relative risk = 1.58; 95% confidence interval, 0.94-2.65; p = .083), whereas the subjective cure rate was significantly lower in the SIMS arm than in the r-TVT arm (57/103 [55.3%] vs 89/106 [84.0%] for the r-TVT and SIMS arms, respectively; relative risk = 0.66; 95% confidence interval, 0.54-0.80]; p < .001). The proportion of retreated patients for SUI/MUI was significantly higher in the SIMS arm than in the r-TVT arm (37/103 [34.9%] vs 12/106 [11.3%] for SIMS and r-TVT arm, respectively; p < .001). CONCLUSION: SIMS has no advantage in terms of safety over r-TVT and was found to be less effective than r-TVT. Thus, its use in the clinical practice should be questioned.

RESUMO

Women with polycystic ovary syndrome (PCOS) seem to have impaired reproductive performances. It is generally considered that an altered ovulatory function is the main cause of infertility in the affected women. However, other factors may play a role in the pathogenesis of the PCOS-related infertility. During the last years, more and more importance has been given to endometrium as contributor of the PCOS-related subfertility. In the present narrative review, the main and recent experimental and clinical data will discuss in order to clarify the role played by the endometrium in the PCOS-related subfertility. The overall analysis of available data suggests that, in women with PCOS, the endometrium is primarily affected, and closely and deeply influenced by the several hormonal, metabolic, clinical alterations related to the syndrome.

RESUMO

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is a complication of controlled ovarian hyperstimulation (COH). It is a potentially life-threatening condition that usually occurs either after human chorionic gonadotropins (hCG) administration in susceptible patients or as a result of an implanting pregnancy, regardless of whether it was achieved by natural conception or infertility treatments. Despite many years of clinical experience regarding the adoption of preventive measures and the identification of patients at high risk, the pathophysiology of OHSS is poorly understood and no reliable predictive risk factors have been identified. CASES PRESENTATION: We report about two unexpected cases of OHSS following infertility treatments, occurring after freeze-all strategy with embryo cryopreservation approaches. The first case developed spontaneous OHSS (sOHSS), despite efforts to prevent its manifestation by a segmentation approach, including frozen embryo replacement cycle. The second case developed a late form of iatrogenic OHSS (iOHSS), even though the absence of any risk factors. No mutations in the follicle-stimulating hormone (FSH) receptor (FSHR)-encoding gene were detected, suggesting that the high levels of hCG due to the twin implanting pregnancies could be the only triggering factor of OHSS outbreak. CONCLUSION: Freeze-all strategy with embryo cryopreservation cannot entirely prevent the development of OHSS, which may occur in its spontaneous form independently from the FSHR genotype. Although OHSS remains a rare event, all infertile patients requiring ovulation induction or controlled ovarian stimulation (COS) may be at potential risk of OHSS, either in the presence or in the absence of risk factors. We suggest closely monitoring cases of pregnancy following infertility treatments in order to provide early diagnosis and adopt the conservative management.

RESUMO

OBJECTIVE: Foetal exposure to high testosterone concentrations seems to be involved in the development of mammalian brain and related to pervasive developmental disorders (PDDs). The aim of the current study was to test the hypothesis that children born from hyperandrogenic women with polycystic ovary syndrome (PCOS) are at higher risk of PDDs. DESIGN: Longitudinal case-control study. PATIENTS: Thirty pregnant PCOS patients with hyperandrogenaemia and other 45 pregnant healthy women were followed during pregnancy. All women had a healthy baby. MEASUREMENTS: Clinical evaluations and biochemical assays of the mothers during pregnancy and after delivery were performed. The children's versions of the Autism-Spectrum Quotient (AQ-C), the Empathy Quotient (EQ-C) and Systemizing Quotient (SQ-C) tests were administered. RESULTS: Total AQ-C and communication scores were significantly higher for children of PCOS patients. Stratifying our population according to sex, total AQ-C, communication and attention switching subscores were significantly higher only for daughters of PCOS patients. EQ-C and SQ-C scores resulted in significantly lower and higher scores, respectively, only in daughters of PCOS patients in comparison with those of healthy non-PCOS controls. AQ-C, EQ-C and SQ-C scores, irrespective of the studied group and/or subclassification by gender, were significantly influenced by amniotic testosterone levels. CONCLUSIONS: Daughters of mothers affected by hyperandrogenic PCOS seem to have a higher risk for PDDs probably due to an unbalanced prenatal exposure to high levels of testosterone.

RESUMO

Obesity is known to interfere with reproductive outcomes in polycystic ovary syndrome. There is no consensus regarding the impact of obesity on reproductive outcomes after ovarian ablative therapy (OAT) and there is no level I evidence to answer this question. This systematic review and meta-analysis assessed the strength of the association between obesity and ovulation or pregnancy rates after OAT. MEDLINE and several other databases were searched from 2000 to September 2011 for studies reporting on OAT and reproductive outcomes. Data were synthesized to determine the relative risk of reproductive outcomes (ovulation and pregnancy) in lean (body mass index <25 kg/m(2)) compared with overweight or obese women. The study obtained 15 data sets (14 articles) for analysis, which included 905 subjects in the obese group and 879 subjects in the lean group. Lean women had increased ovulation rates (RR 1.43, 95% CI 1.22-1.66) compared with obese women. Pregnancy rates also showed a similar trend (RR 1.73, 95% CI 1.39-2.17). Reproductive outcomes were generally better in younger women, more recent studies and randomized controlled trials. It is concluded that lean women respond better to OAT than their obese counterparts. These epidemiological observations indicate that obesity alters reproductive outcomes after OAT negatively. Obesity is known to interfere with reproductive outcomes in polycystic ovary syndrome. There is no consensus regarding the impact of obesity on ovarian ablative therapy (OAT) and there is no level I evidence to answer this question. We therefore undertook a systematic review and meta-analysis to assess the strength of the association between obesity and ovulation or pregnancy rates after OAT. We searched MEDLINE and several other databases from 2000 to September 2011 for studies reporting on OAT and reproductive outcomes. Data were synthesized to determine the risk ratio of reproductive outcomes (ovulation and pregnancy) in lean (BMI <25 kg/m(2)) as opposed to overweight or obese women. We obtained 15 datasets (14 articles) for analysis, which included 905 subjects in the obese group and 879 subjects in the lean group. Lean women had increased ovulation rates (RR 1.43, 95% CI 1.22-1.66) as compared to obese women. Pregnancy rates also showed a similar trend (RR 1.73, 95% CI 1.39-2.17). Reproductive outcomes were generally better in younger women, more recent studies and randomized controlled trials. We conclude that lean women respond better to OAT than their obese counterparts. These epidemiological observations indicate that obesity alters reproductive outcomes after OAT negatively.

RESUMO

The aim of the current study was to compare the safety of the laparoscopic vs abdominal approach to staging endometrial cancer. A search was conducted for randomized controlled trials that reported data from women with histologically confirmed endometrial cancer who underwent laparoscopic or abdominal surgery. An additional metaanalysis was performed. The primary endpoints were the rates of intraoperative and postoperative complications. A total of 8 original randomized controlled trials were included in the final analysis. No significant difference was observed in the relative risk (RR) for intraoperative complications between laparoscopy and laparotomy (RR, 1.25; 95% confidence interval, 0.99-1.56; P = .062). In contrast, a significant advantage of laparoscopy over laparotomy was obtained in terms of postoperative complications (RR, 0.71; 95% confidence interval, 0.63-0.79; P = .016). In comparison with abdominal surgery, the safety of the laparoscopic approach for surgical staging of endometrial cancer is similar in terms of intraoperative complications but results in fewer postoperative complications.

RESUMO

OBJECTIVE: The objective of this study was to give a reality-based picture of the use of laparoscopic surgery for staging endometrial cancer patients out of the experimental setting. METHODS: Consecutive data of patients with endometrial cancer who underwent laparoscopic or abdominal surgical staging in 6 Italian centers were recorded. Baseline patients and tumors characteristics, surgery performed, and safety data were collected and analyzed. RESULTS: A total of 1012 subjects (403 and 609 treated by laparoscopy and laparotomy, respectively) who received surgical stadiation for endometrial cancer were included in the final analysis. The laparoscopic approach to endometrial cancer was more commonly performed in younger and nonobese patients who had received less previous surgeries, whereas the abdominal approach was preferred for the advanced stages and rare histotypes. Irrespectively to stage, the operative time was higher for the laparoscopy than laparotomy, whereas blood loss and postoperative complications were lower in the laparoscopy group than in the laparotomy group. No difference between surgical approaches was observed in complication rates in stage I endometrial cancers, whereas they were worst in higher stages. The site, but not the incidence, of recurrences differed only for advanced stage endometrial cancers. No differences in overall, disease-free, and cancer-related survival rates were also observed. CONCLUSIONS: In the clinical practice, heterogeneous criteria are adopted to recur to laparoscopy for staging endometrial cancer. The safety and the feasibility of the laparoscopy are confirmed for stage I endometrial cancers, whereas they appear suboptimal for the advanced stages.

RESUMO

Nexplanon(®) is a new long-term reversible contraception method. The current review is aimed to analyze the published data concerning the contraceptive effectiveness of Nexplanon(®) and its effects on reproductive function. Pharmacological properties and technical procedures of insertion and removal, as well as the efficacy and safety data available, were discussed. Possible strategies for treating Nexplanon(®)-related bleeding were also described. With regard to the future research and the future scientific developments of contraceptive implants, the possible use of Nexplanon(®) wide-ranging for the symptomatic treatment of endometriosis and premenstrual syndrome (PMS) were considered. Finally, it was defined in which women the use of Nexplanon(®) is indicated and in which it is contra-indicated.
