Abstract Study question Is men’s adherence to the Mediterranean diet (MD) associated with sperm parameters and couples’ outcomes of assisted reproductive technologies (ART)? Summary answer Higher men’s adherence to the MD was associated with an increased probability of clinical pregnancy and live birth among couples undergoing ART. What is known already There is growing literature supporting the hypothesis that some nutrients, foods, and dietary patterns may be related to sperm quality and fertility. However, no previous studies analyzed the relationship of men’s adherence to the Mediterranean diet with sperm parameters and ART outcomes in the same cohort. Study design, size, duration The Environmental and Reproductive Health (EARTH) Study is a prospective preconception cohort of couples seeking fertility treatment at the Massachusetts General Hospital Fertility Center (Boston, USA). This analysis includes 314 men and their female partner, who underwent 791 ART cycles (2007–2020). Diet intake was measured by a validated semi-quantitative food frequency questionnaire completed prior to ART. Men’s adherence to the MD was estimated using the Trichopoulou score. Participants/materials, setting, methods Primary outcomes included: conventional sperm parameters (volume, sperm count, concentration, motility, and morphology), and ART outcomes (implantation, clinical pregnancy, and live birth). We estimated the marginal means and 95% confidence interval (95%CI) for semen parameters and the probability of ART (95%CI) by employing generalized linear mixed models while adjusting for several potential confounders. Sensitivity analyses by changing the cut-off points of adherence to the MD were tested. Main results and the role of chance At baseline, men had a median (IQR) age of 35.6 (32.6, 38.8) years and a BMI of 26.7 (24.0, 29.4) kg/m2. Female partner age median (IQR) was 35.0 years (32.0, 38.0) and BMI 23.3 (21.3, 26.6) kg/m2. Couples were mostly white and had never smoked. Men’s adherence to the MD was not associated with seminal parameters in the multivariable-adjusted models but it was related to a higher probability of clinical pregnancy and live birth. The predicted marginal proportions and confidence intervals among men in the lowest compared with the highest quartile of adherence to the MD were 0.25 (0.14, 0.40), 0.55 (0.41, 0.68) for clinical pregnancy (P-trend=0.005), and 0.19 (0.10, 0.32), 0.42 (0.30, 0.55) for live birth (P-trend=0.014). Male partner MD dietary pattern scores were unrelated to the probability of implantation. Sensitivity analyses using tertiles and quintiles of men’s adherence to the MD showed similar associations. Limitations, reasons for caution Although we have adjusted our models by several potential confounding factors, residual confounding cannot be ruled out, and therefore our results should be interpreted with caution. The findings may not be generalizable to other populations or couples attempting conception without ART. Wider implications of the findings: According to our knowledge, this is the first study suggesting that adherence to MD could be suitable dietary guidance for men whose partners are undergoing infertility treatment.

Abstract Study question Is there a relationship between dietary patterns and clinical pregnancy or live birth outcomes in men and women of reproductive age undergoing assisted reproductive technologies (ART)? Summary answer While the Mediterranean and pro-fertility diets show potential to improve fertility outcomes, the association between dietary patterns and ART success is currently inconsistent. What is known already The nutritional status of reproductive-aged couples can have a significant impact on fertility. While the consumption of individual foods and nutrients are known to influence reproductive success, the effect of dietary patterns on clinical pregnancy and live birth outcomes in people using assisted reproductive technologies (ART) is currently unknown. Study design, size, duration Six electronic databases were systematically searched for original research published in English between January 1978 and December 2020 reporting on the effect of pre-defined dietary patterns on either clinical pregnancy and/or live birth rates following invitro fertilisation or intracytoplasmic sperm injection in men and women aged 18–49 years. Screening of all retrieved articles was performed independently by two review authors. Eligible studies underwent quality assessment and qualitative and quantitative synthesis using random-effects model meta-analyses. Participants/materials, setting, methods Studies eligible for inclusion in this systematic review were cross-sectional, cohort, clinical trial, and randomised controlled trial study designs. Eligible participants were both males and females, aged 18–49 years, who were undergoing invitro fertilisation or intracytoplasmic sperm injection. Studies were excluded if their primary analysis assessed consumption of individual foods, food groups, vitamins, or minerals, rather than dietary patterns. Studies measuring proxy estimates of fertility status such as sperm quality or quantity were not included. Main results and the role of chance Twelve studies (11 prospective cohort studies, 1 randomised controlled trial) reporting on 3144 participants (92% female) were included in the review. Six studies were of positive methodological quality, and six were of neutral quality. Eleven studies used validated food frequency questionnaires to quantify dietary pattern adherence. In individual studies, three dietary patterns (Mediterranean diet, pro-fertility diet, Iranian traditional medicine diet) were associated with increased likelihood of achieving a clinical pregnancy, while two dietary patterns (pro-fertility diet, Mediterranean diet) were associated with increased probability of live birth. Meta-analyses of five Mediterranean diet cohort studies showed no association between dietary pattern and clinical pregnancy (OR 1.3; 95% CI: 0.73- 1.72, P = 0.59), and meta-analysis of three Mediterranean diet cohort studies found no relationship between dietary pattern and live birth (OR 1.51; 95% CI: 0.83–2.76, P = 0.18). Limitations, reasons for caution Males were under-represented in the included studies, and half of the studies were of neutral methodological quality. All studies completed dietary assessments at baseline only, however dietary assessments should ideally be undertaken at regular intervals throughout the duration of cohort studies, in the event that dietary patterns change over time. Wider implications of the findings: Further research utilising higher quality nutrition research methodologies is required to better understand the association between dietary patterns and fertility outcomes during assisted reproductive technologies.

Background: Studies have reported the association between cardiorespiratory fitness and higher adherence to the Mediterranean diet as well as lower recreational screen time. Similarly, higher screen time has been negatively linked to a lower adherence to the Mediterranean diet. However, the mediator effect of cardiorespiratory fitness on the influence of screen time on adherence to the Mediterranean diet is still unknown. The aim of this study was two-fold: first, to assess the combined association of recreational screen time and cardiorespiratory fitness with adherence to Mediterranean diet among Spanish schoolchildren, and second, to elucidate whether the association between recreational screen time and adherence to the Mediterranean diet is mediated by cardiorespiratory fitness. Methods: A descriptive and cross-sectional study was conducted. A total of 370 schoolchildren aged 6–13 years from six schools in the Region of Murcia (Spain) were included. Results: The mediation analysis showed that once screen time and cardiorespiratory fitness were included together in the model, cardiorespiratory fitness was positively linked to adherence to the Mediterranean diet (p = 0.020) and although screen time remained negatively related to adherence to the Mediterranean diet, this association was slightly attenuated (indirect effect = −0.027; 95% CI = (−0.080, −0.002)). Conclusions: This research supports that cardiorespiratory fitness may reduce the negative association between screen time and Mediterranean dietary patterns.

Objective: The preconception period is largely neglected, whereas it represents an opportunity to identify and modify clinical and behavioral risks, particularly in infertile women characterized by an unfavorable vascular burden. The present study was performed to strengthen previous findings and to increase the awareness of clinicians who should envision a broader preconception approach in infertile women, beyond their reproductive health. Materials and methods: In this cross-sectional study, we investigated 1003 Caucasian women, referred to the Internal Medicine Clinic at the Assisted Reproductive Technologies Center, Florence. Results: A high prevalence of dyslipidemia (57.4%), overweight/obesity (29.1%) and, smoking habit (26.6%) were found. We provided evidence of unhealthy lifestyle habits, represented by a closer adherence to the Mediterranean diet in the 9.5% only and by a sedentary behavior in 73%. A significant correlation between the Mediterranean Diet score and both anthropometric and metabolic parameters was found. We also observed a lower score adherence with both metabolic syndrome and diabetes (for both p=0.02), but not with hypertension. Conclusion: Before infertility treatment, the correction and the management of modifiable and non-modifiable cardiovascular risk factors are mandatory and represent the main goal for a safe pregnancy, and lifetime women’s health.

The paper analyzes the literature data on the use of the growth hormone (GH) in ovarian stimulation in assisted reproductive technologies (ART). Routine use of GH in ovarian stimulation in patients with a normal GH level does not increase pregnancy and childbirth rates in ART. Also, no benefits of using GH have been identified for patients with polycystic ovary syndrome, despite the increase in insulin and IGF-1 blood levels. The main research focus is to study the use of GH in patients with poor ovarian response. According to the meta-analysis conducted by X.-L. Li et al. (2017), GH in ovarian stimulation of poor ovarian responders increases the number of received oocytes, mature oocytes number, reduces the embryo transfer cancellation rate and does not affect the fertilization rate. The pregnancy and live birth rates are significantly higher in the group of GH use - by 1.65 (95% CI 1.23-2.22) and 1.73 (95% CI 1.25-2.40) times, respectively. Thus, it is advisable to use GH in ovarian stimulation in poor ovarian responders, since it allows to increases live birth rate in ART. However, further studies should determine the optimal GH dose and assesse it`s safety in ART programs.

The aim of the study is to systematically analyze the data available in the modern literature on the relationship between endometrial thickness and the frequency of pregnancy in the program of assisted reproductive technologies (ART). Materials and methods. The review includes data from foreign and domestic articles found in PubMed on this topic. Results. The article presents data on the relationship between the thickness of the endometrium and the frequency of pregnancy in ART programs. The greatest number of studies is devoted to the evaluation of the relationship between the thickness of the endometrium and the frequency of pregnancy on the day of the ovulation trigger. Data are presented on the existence of a correlation between the thickness of the endometrium measured on the day of the ovulation trigger and the frequency of clinical pregnancy, as well as data on the need to evaluate the structure of the endometrium and the state of subendometric blood flow. The importance of multilayered (three-layered) endometrium as a prognostic marker of success in in vitro fertilization/intracytoplasmic sperm injection programs in the ovum is emphasized. The conclusion. The thickness of the endometrium can not be used as an argument for canceling the cycle or abolishing embryo transfer to the uterine cavity. Further studies in this direction are needed with a study of the morphological and molecular genetic characteristics of the endometrium, which in the future will allow us to evaluate the relationship between the thickness of the endometrium and the probability of pregnancy.

BackgroundOvaleap® (follitropin alfa), a recombinant human follicle stimulating hormone, is a biosimilar medicinal product to Gonal-f® and is used for ovarian stimulation. The main objective of this study was to assess the safety and effectiveness of Ovaleap® compared to Gonal-f® in one treatment cycle in routine clinical practice.MethodsSafety of Ovaleap® Follitropin alfa in Infertile women undergoing superovulation for Assisted reproductive technologies (SOFIA) was a prospective cohort study conducted in six European countries. Eligible patients were infertile women undergoing superovulation for assisted reproductive technology, who were administered Ovaleap® or Gonal-f® for ovarian stimulation and were naïve to follicle stimulating hormone treatment. The recruitment ratio was 1:1. The primary endpoint was incidence proportion of ovarian hyperstimulation syndrome (OHSS) and the secondary endpoint was OHSS severity (Grades I, II, III). The effect of risk factors or potential confounders on the odds ratio for OHSS incidence as well as treatment effect on OHSS incidence was explored using univariate logistic regression. Pregnancy and live birth rates were also assessed.ResultsA total of 408 women who were administered Ovaleap® and 409 women who were administered Gonal-f® were eligible for analysis. The incidence proportion of OHSS was 5.1% (95% CI: 3.4, 7.7) in the Ovaleap® cohort and 3.2% (95% CI: 1.9, 5.4) in the Gonal-f® cohort. This difference in OHSS incidence proportion between the two cohorts was not statistically significant neither before (p = 0.159) nor after univariate adjustment for each potential confounder (p > 0.05). The incidence proportion of OHSS severity grades was similar in the two treatment groups (3.4% versus 2.0% for Grade I, 1.2% versus 1.0% for Grade II, and 0.5% versus 0.2% for Grade III, in the Ovaleap® and Gonal-f® cohorts, respectively), without a significant statistical difference (p = 0.865, for each grade). Among patients who had embryo transfer, clinical pregnancy rates were 33% and 31% and live birth rates were 27% and 26%, in the two cohorts, respectively.ConclusionsFindings from the SOFIA study indicate that the incidence proportions of OHSS and OHSS severity, as well as pregnancy and live birth rates, are similar between Ovaleap® and Gonal-f® treatments and corroborate the safety and effectiveness of Ovaleap® as a biosimilar to Gonal-f®.

In order to increase the effectiveness of assisted reproductive technologies (ART) programs, it is essential to improve and develop conditions of embryo culture prior its transfer or cryopreservation of expanded blastocysts on the day 5 or 6. The aim of the study was to assess the effect of human blastocysts’ expansion timing on clinical pregnancy rate (CPR), miscarriage rate (MR) and take-home baby rate (THBR) in frozen-thawed cycles during ART programs. The study involved 2275 frozen embryo transfers (FET) of blastocysts expanded on the day 5 (group A) and 170 FET of blastocysts expanded on the day 6 (group B). The pregnancy rates in both groups were 50.8% and 46.5% respectively. There were no statistically significant differences in clinical pregnancy rate 37.4% and 37.0%, miscarriage rate 26.0% and 21.5% in both groups, respectively. THBR, as the main indicator of efficiency in the programs with transfer of post thawed expanded blastocysts on the day 5 (group A) or 6 (group B) were 36.5% and 35.2%, respectively (the difference is insignificant). In conclusion, in cryoprotocols the day of blastocyst expansion (day 5 or 6 of development) does not statistically affect PR, MR and THBR. In FET programs the quality of blastocyst (excellent and good) should be prioritized regardless of the day of cryopreservation.
