RESUMEN

Laparoscopic surgery was originally considered the gold standard in the treatment of endometriosis-related infertility. Assisted reproductive technology (ART) was indicated as second-line treatment or in the case of male factor. The combined approach of surgery followed by ART proved to offer higher chances of pregnancy in infertile women with endometriosis. However, it was highlighted how pelvic surgery for endometriosis, especially in cases of ovarian endometriomas, could cause iatrogenic damage due to ovarian reserve loss, adhesion formation (scarring), and ischemic damage. Furthermore, in the last few years, the trend to delay the first childbirth, recent technological advances in ultrasound diagnosis, and technological progress in clinical and laboratory aspects of ART have certainly influenced the approach to infertility and endometriosis with, ART assuming a more relevant role. Management of endometriosis should take into account that the disease is chronic and involves the reproductive system. Consequently, treatment and counselling should aim to preserve the chances of pregnancy for the patient, even if it is not associated with infertility. This review will analyse the evolution of the management of infertility associated with endometriosis and propose an algorithm for treatment decision-making based on the most recent acquisitions.

RESUMEN

BACKGROUND: Hormonal fertility treatments are associated with increased coagulation factors inducing procoagulant milieu and possibly thrombotic risk. OBJECTIVE: To assess coagulation by ROTEM and coagulation tests in apparently healthy infertile women before oocyte donation procedure. METHODS: We enrolled 51 women (Assisted Reproductive Technology Centre, Florence). ROTEM and coagulation parameters were assessed before the start of infertility treatment. RESULTS: We divided women in 3 groups according to the number of cardiovascular risk factors: Group A (n = 10), Group B (n = 16), and Group C (n = 25). By considering ROTEM Extem test, a significantly increased of MCF, TPI, and G were observed in groups B (p = 0.005, p = 0.03, and p = 0.007) and C (p = 0.01, p = 0.05, and p = 0.005) in comparison to group A. As regards ROTEM Intem test, the TPI and G values were significantly higher in groups B and C in comparison to group A (p < 0.01). MCF by Fibtem test significantly increased in groups B and C than in group A (p = 0.004 and p = 0.002, respectively). FVIII, vWF:Ag and D-dimer values significantly increase according to the presence of≥2 risk factors. CONCLUSIONS: Data from coagulative assessment permit to sensitively identify women with potentially procoagulable state, which represents a risk factor of thromboembolic event during hormone treatment.

RESUMEN

PURPOSE: On March 8, 2020, the Italian Government implemented extraordinary measures to limit viral transmission of COV-19/SARS-CoV-2. We evaluated the impact of COVID-19 lockdown on lifestyle and emotional state in women planning infertility treatments. BASIC PROCEDURES: We performed a quantitative research study using a web-based survey, in 140 women referred to Assisted Reproductive Technologies Center. MAIN FINDINGS: We observed changes in body weight during lockdown in 80 % of women, and a significant increase in BMI in comparison to that observed before (p=.001). We observed a high percentage of non-adherence to the Mediterranean pattern during lockdown due to higher frequency of consumption of sweet/pastries, cheese and meat, rather than fruit, vegetables and legumes. Before lockdown 36.4 % women were snack consumers while during lockdown 55 % (p=.002). By considering individuals' attitude to snack consumption, we observed an increase related to boredom (p=<.0001) and anxiety (p=.05) during lockdown. Increased levels of anxiety and sadness were observed in about 30 %, and of boredom in 25 %. The percentage of women worried about their planning infertility treatment was more than 50 %. PRINCIPAL CONCLUSIONS: Quarantine-related restrictions strongly influenced lifestyle psychological behavior leading to an increased burden of cardiovascular disease.

RESUMEN

PURPOSE: To evaluate the influence of hepatitis B virus (HBV) infection in men of serodiscordant couples on the reproductive outcomes. MATERIALS AND METHODS: A total of 134 infertile couples were included in this retrospective single-center cohort study. Sixty-six couples had hepatitis B surface antigen (HBsAg)-seropositive men and seronegative partners, while 68 couples were controls with both seronegative men and women. Overall, 134 fresh in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatments were performed. As the main outcome measures, on the day of the fresh IVF/ICSI cycle, we assessed seminal parameters Before and after sperm preparation techniques. Two-pronuclear (2PN) fertilization, 1-2-3PN fertilization, cleavage, miscarriage, pregnancy and live birth rates were collected. RESULTS: No significant differences were found between groups in terms of oocytes retrieved, oocytes injected and embryos obtained (p=0.64, p=0.97, and p=0.40, respectively). The 2PN fertilization rate (FR) was comparable among groups (p=0.51). The 1-2-3PN FR was significantly lower in the HBsAg group than in the control group (66.6% vs. 69.7%, respectively). The clinical pregnancy per cycle, implantation, miscarriage and live birth rate were comparable between the HBsAg group and the control group. The median sperm concentration/ml and total sperm count, measured at baseline and after sperm preparation, was comparable between groups (p>0.05). There was a trend toward significant lower progressive motility (35.0% vs. 55.0%; p<0.05) in the HBsAg group at baseline and after sperm preparation (p<0.05). CONCLUSIONS: HBV infected men have the same chance to became father, compared to seronegative patients.

RESUMEN

Background: The last two decades have seen a growing number of pregnancies in women who needed the donation of oocytes. With oocyte donation pregnancies, studies on obstetric outcomes among these women revealed an increased incidence of pre-eclampsia and pregnancy-induced hypertension. Furthermore, several studies have found a higher incidence of low birth weight, preterm birth, and delivery by cesarean section in oocyte donation rather than in women subjected to assisted reproduction techniques (ART) with autologous oocytes. Numerous studies have also shown a deep connection between cardiovascular and thrombotic risk factors and adverse pregnancy outcomes. In this setting, to strictly assess the preconceptional risk for women who undergo egg donation to achieve pregnancy, the aim of our study is to draw a detailed assessment of the vascular risk profile of patients with gamete donation ART indications through the evaluation of comorbidities and cardiometabolic and thrombophilic markers Materials and Methods: Patients undergoing ART with oocyte or sperm donation or double donation of gametes underwent a careful clinical assessment through a detailed personal and family anamnesis and they were evaluated for cardiometabolic and thrombophilic profile. Clinical and demographic characteristics, comorbidities, and biohumoral parameters were collected. The study was approved by the Regional Ethical Committee(Em 2018-017 CINECA 10189). Results: We evaluated 525 women. Around 73.1% were >40 years and 35% of them were older than 45 years. There was a high prevalence of dyslipidemias (58.1%), smoking habit (24.6%), a body mass index >25 in 28.6% of patients, a high abdominal circumference in 58.1% of cases, a prevalence of acquired thrombophilia in about 7% and hereditary of 19.2%. Around 39.2% of patients had total cholesterol >200 mg/dL, 19.5% had high-density lipoprotein <48 mg/dL and 43.6% had low-density lipoprotein >115 mg/dL, and 6.9% had triglyceride values >150 mg/dL. Conclusions: A careful assessment of the preconceptional status of patients undergoing ART programs with oocyte donation can be highly recommended.

RESUMEN

PURPOSE: To evaluate the effectiveness, efficiency, and safety of a transnational gamete donation (TGD) programme based on the shipping of vitrified donor oocytes. METHODS: A retro-prospective observational study was conducted in the Assisted Reproductive Technology Center of the University Hospital of Florence, Italy. The study population included 622 consecutive donor oocyte cycles. A mean number of 6 vitrified oocytes per couple were shipped from two Spanish biobanks. In the receiving centre, gametes were warmed and inseminated and the subsequent embryo transfer (ET) was performed. The main outcome measurement was LBR. Secondary outcomes included oocyte survival rate, ICSI damage rate, normal fertilization, cleavage, and implantation rate (IR) in both 'fresh' and cryotransfer cycles. RESULTS: A total number of 3536 mature oocytes were warmed with 81.4% surviving oocytes. 2PN oocytes were 1941 with an ICSI normal fertilization rate of 70.4% and a cleavage rate of 93.4%; 857 day-3 embryos were transferred in 498 women, 63 blastocysts in 44. Couples with at least one vitrified embryo were 181 (32.3%). IR was 25.1% and 33.1% for day-3 ET and blastocyst stage respectively. Crude pregnancy rate and LBR after the first ET were 35.5% and 27% correspondingly with a conservative cumulative LBR of 34% and an optimal LBR of 51.4%. CONCLUSION: Imported vitrified donor oocytes retain their competence and are capable of resulting in ongoing pregnancies and healthy babies in a proportion comparable to other existing systems as egg donation with vitrification/warming in the same laboratory and transnational fresh oocyte donation.

RESUMEN

RESEARCH QUESTION: To evaluate pre-existing comorbidities, obstetric risk factors and adverse obstetric and neonatal outcomes in pregnancies conceived by oocyte donation, compared with naturally conceived pregnancies or by conventional IVF/intracytoplasmic sperm injection (IVF/ICSI). DESIGN: This retrospective single-centre contemporary cohort study reviewed data from singleton deliveries at the University Hospital of Careggi, Florence, from 2009 to 2017. Maternal and perinatal outcomes were analysed. RESULTS: The study included 25,851 pregnancies and newborns: 276 (1.1%) children were conceived after oocyte donation, 925 (3.6%) after IVF/ICSI and 24,650 (95.4%) after natural conception. Women in the oocyte donation group were significantly older compared with IVF/ICSI and natural conception groups (P < 0.0001) and had a higher prevalence of chronic hypertension compared with the natural conception group (P = 0.0090). They were administered anticoagulant medications more frequently during pregnancy. The incidence of gestational hypertension was significantly higher than in natural conception (aOR 3.6) and IVF/ICSI pregnancies (aOR 2.7). The incidence of Caesarean section in oocyte donation pregnancies was higher than in natural conception and IVF/ICSI groups (aOR 3.4 and 2.3, respectively). An 11-fold increased risk of post-partum haemorrhage (PPH) was found in oocyte donation versus natural conception and an almost four-fold increased risk was found in oocyte donation versus IVF/ICSI; prematurity and low birthweight were more frequent after oocyte donation versus natural conception (aOR 2.4 and 1.8, respectively). CONCLUSIONS: Patients undergoing oocyte donation represent a group with increased comorbidities and risk factors for adverse obstetric outcomes. Oocyte donation seems to be independently associated with gestational hypertension and PPH. Pregnancies after oocyte donation warrant clinical surveillance with proper screening and, possibly, preventive strategies.

RESUMEN

Our objective was to investigate whether the chronic cytomegalovirus (CMV) infection can affect semen parameters in men with couple infertility and to assess the impact of male CMV infection on the reproductive outcomes of CMV-seronegative women suffering from tubal factor. Group 1 included CMV IgG-seropositive men, Group 2 CMV IgG-seronegative patients. Seminal parameters, two-pronuclear (2PN) fertilization rate (FR), 1-2-3PN FR, cleavage rate (CR), miscarriage rate (MR), pregnancy rate (PR) and live birth rate (LBR) were collected. Two hundred and twenty-two men were included: 115 (51.8%) in Group 1 and 107 (48.2%) in Group 2. There was reported a low trend towards higher sperm concentration/ml, total sperm count and viability in CMV IgG-seronegative males, compared to CMV IgG-seropositive (p > .05). Semen volume, pH, motility and normal sperm morphology were similar among groups. Considering the subgroup of men, partners of CMV IgG-seronegative females, 65 couples (29.2%) were selected. Median 2PN FR was 67%, total FR 83%, CR 100%, PR/cycle 26.2%, MR 10.8%, LBR/cycle 15.4%. No significant differences were found regarding the reproductive outcomes between CMV IgG-seropositive men and those seronegative. CMV did not seem to play a key role in male reproductive function, as well as in influencing sperm fertility potential in the assisted reproductive outcomes.

RESUMEN

Endometriosis is a gynecological disease characterized by pain and infertility. The diagnosis is very often made during the infertility work-up, together with other reproductive diseases and uterine disorders. A retrospective cohort study was conducted on infertile women with clinical or ultrasound suspect of endometriosis, undergoing an ultrasound (US) evaluation by a team of expert sonographers (n = 419), with the aim to evaluate the prevalence of concomitant uterine disorders. The US coexistence of endometriosis with uterine fibroids and/or adenomyosis was investigated according to three age intervals (<35years; 35 ≥ years <45; ≥45 years) and to endometriosis phenotypes: ovarian endometriosis (OMA), deep infiltrating endometriosis (DIE), or both. The US diagnosis of fibroids was made in 3.1% of cases, adenomyosis was found in 21.2%, and the co-existence of both uterine disorders with endometriosis was reported in 14.6% of patients. When analyzed according to age, patients aged >35 years were more likely to be affected by uterine fibroids (p = .003), adenomyosis (p = .030) and both adenomyosis and fibroids (p < .0001). No statistically significant association was found between endometriosis phenotypes and myometrial pathologies. Uterine disorders coexistence should be considered in the assessment of women with endometriosis, in order to better define a treatment strategy for infertility, especially in women older than 35 years.

RESUMEN

The pathophysiology of severe endometriosis in young women remains unknown. Menorrhagia, or heavy and prolonged menstrual bleeding, is the most common symptom experienced by women with von Willebrand disease (vWD) and represents a possible risk factor for developing endometriosis. A 17-year-old woman affected by vWD presented with severe dysmenorrhea and heavy menstrual bleeding. After being diagnosed with multiple ovarian endometriomas, the patient underwent repeated surgeries due to suspicious appearance of recurrent pelvic masses. vWD may be a risk factor for developing severe endometriosis, and patients with endometriosis should be screened for vWD and other bleeding disorders. Ovarian endometriomas in such patients might present a more severe progression and unique ultrasound findings, mimicking malignancies.

RESUMEN

To investigate the incidence of adverse pregnancy outcomes in couples with an unexplained Recurrent Pregnancy Loss (RPL) history, a retrospective cohort study was conducted between 2014 and 2015. The study group (A) included couples with an unexplained RPL, and the control group (B) was composed of couples who attended the Low-Risk Antenatal Unit during the same period. On the other hand, 53 couples were included in the study group (A) and on the other hand, 65 in the control group (B). Women with previous unexplained recurrent pregnancies loss had a significantly increased risk of gestational diabetes with 12 cases (22.6%) in the study group and 3 cases (4.6%) in the control (OR: 6.048; 95% CI: 1.607-22.762; p = 0.007). A slight increase in the risk of preterm delivery and hepatic cholestasis was observed in the study group (6 cases, 11.3%, in study group and 1 case, 1.5% in the controls (OR: 8.170; 95% CI: 0.951-70.158; p = 0.0555). Women with a history of RPL delivered more frequently by caesarean section (OR: 3.252; 95% CI: 1.460-7.241; p = 0.0039). Women with a history of RPL were at an increased risk for adverse pregnancy outcomes, mainly gestational diabetes. Therefore, a closer surveillance during the antenatal period is recommended in this group of patients.

RESUMEN

To study whether unoperated ovarian endometrioma(s) or its surgical excision led to a modified pattern of ovarian decay with increasing female age. A sectional analysis of basal follicle stimulating hormone (FSH) and ovarian response to gonadotropins was conducted on women treated with fresh autologous In Vitro Fertilization/Intracytoplasmic sperm injection (IVF/ICSI) cycles. The study group included patients with unoperated ovarian endometrioma(s) (108 cycles); control groups were women with previous surgery for monolateral ovarian endometrioma (101 cycles), surgery for bilateral ovarian endometriomas (39 cycles), and tubal factor infertility (171 cycles). Simple linear regression analyses and the Pearson correlation were used to analyze the correlation between basal FSH, number of dominant follicles, number of retrieved oocytes, and age of patients. The relationship between the variables was significant in case of patients with nonoperated ovarian endometrioma(s) and patients with previous surgery for monolateral endometrioma and tubal factor infertility group. In patients with a history of surgery for bilateral endometriomas, no relationship was found among the variables (basal FSH 95% confidence interval [CI]: -0.475 to 0.319; P = .688; number of dominant follicles 95% CI: -0.484 to 0.382; P = .808; number of retrieved oocytes 95% CI: -0.478 to 0.370, P = .792). In women with unoperated ovarian endometrioma(s) or with a history of surgery for monolateral endometrioma, the remaining ovarian parenchyma maintains the same pattern of ovarian decay as healthy ovaries. Unoperated ovarian endometriotic lesions did not interfere with ovarian reserve and IVF/ICSI cycles' outcomes and were less injurious than surgery. After surgery for bilateral ovarian endometriomas, a decline in ovarian reserve seems independent from the patient's age.

RESUMEN

We assessed the outcome of pregnancy in women with a history of recurrent pregnancy loss (RPL) following treatment with low-dose human menopausal gonadotropin (HMG)+progesterone or progesterone alone. This single-center retrospective cohort study included data from women diagnosed with RPL and treated between February 2005 and December 2012 with one cycle of HMG + progesterone or progesterone alone. Primary endpoint was the rate of ongoing pregnancies and losses by treatment, age (<38 vs. ≥38 years) and in the subgroup with unexplained RPL. Of 169 RPL patients, 35.5% (n = 60) received HMG + progesterone and 64.5% (n = 109) progesterone alone. Compared to progesterone alone, HMG + progesterone led to a lower, although not significant, frequency of losses (3.3% vs. 11.9%, p = .09) and a twofold higher rate of ongoing pregnancies (41.7% vs. 19.3%, p = .002). Similar results were obtained in the subgroup of patients with unexplained RPL (ongoing pregnancies: 48.1% upon HMG + progesterone vs. 21.3% upon progesterone, p = .03; losses: 0% vs. 8.5%, respectively, p = .29) and in those <38 years (ongoing pregnancies: 47.4% vs. 18.8%, respectively, p = .003; losses: 5.3% vs. 10.9% respectively, p = .47). These findings suggest that HMG in women with RPL may reduce the rate of miscarriages and increase that of live births regardless of RPL cause and in women aged <38 years.

RESUMEN

Oxidative stress plays a major role in critical biological processes in human reproduction. However, a reliable and biologically accurate indicator of this condition does not yet exist. On these bases, the aim of this study was to assess and compare the blood and follicular fluid (FF) redox status of 45 infertile subjects (and 45 age-matched controls) undergoing in vitro fertilization (IVF), and explore possible relationships between the assessed redox parameters and IVF outcomes. Reactive Oxygen Species (ROS) production, assessed by flow cytometry analysis in blood leukocytes and granulosa cells, significantly increased (p < 0.05) in infertile patients. Also, oxidative stress markers-ThioBarbituric Acid-Reactive Substances (TBARS) as an index of lipid peroxidation, and Oxygen Radical Absorbance Capacity (ORAC) to account for total antioxidant capacity, both assayed by fluorometric procedures-in blood and FF were significantly (p < 0.001) modified in infertile patients compared to the control group. Moreover, a significant correlation between blood redox markers and FF redox markers was evident. An ORAC/TBARS ratio, defined as the redox index (RI), was obtained in the plasma and FF of the patients and controls. In the patients, the plasma RI was about 3.4-fold (p < 0.0001) lower than the control, and the FF RI was about six-fold (p < 0.0001) lower than the control. Interestingly, both the plasma RI and FF RI results were significantly correlated (p < 0.05) to the considered outcome parameters (metaphase II, fertilization rate, and ongoing pregnancies). Given the reported findings, a strict monitoring of redox parameters in assisted reproductive techniques and infertility management is recommended.

RESUMEN

OBJECTIVES: The objective of the study was to evaluate the correlation between endometrioma-associated pain and lesion vascularization as measured with 3-dimensional power Doppler transvaginal sonography. METHODS: Endometriomas were examined, and 4 indices were obtained: mean grayness, flow index, vascularization index, and vascularization-flow index. Dysmenorrhea, chronic pelvic pain, and dyspareunia were analyzed in terms of severity, presence/absence, and duration. RESULTS: Twenty-nine women were selected. The univariable association of painful symptoms in terms of presence/absence and duration was low with the exception of mean grayness with the presence of chronic pelvic pain (ß = -0.106; P = .047; 95% confidence interval, 0.810 to 0.998). The R2 value increased to 0.226 for dysmenorrhea (ß = -0.475; P = .029) when analyzing the association between the vascularization index and the severity of painful symptoms. The visual analog scale scores for chronic pelvic pain and dyspareunia were higher (R2 = 0.300; ß = -0.547 and -0.548, respectively; P = .028 and .053). CONCLUSIONS: We observed an inverse association between the severity of pain and endometrioma vascularization. Further larger studies are required to confirm our findings.
