RESUMO
Currently, there is a growing interest in the study of fertility because fertility-related problems affect up to 15% of the world's population. The aim of this study was to determine the influence of the Mediterranean diet on seminal quality in men of reproductive age. For this purpose, a systematic review of the literature was carried out following the PRISMA method. Electronic searches were carried out in the international databases PubMed, Scopus, the Cochrane Library, and Web of Science. In total, 10 articles with 2032 men were included. As inclusion criteria, articles published between 2012 and 2022 were selected, including those that included men aged between 18 and 55 years. Nutritional status was assessed through weight, height, and BMI. Dietary habits were evaluated through different indexes and food frequency questionnaires, and finally, semen quality was evaluated by measuring sperm concentration and motility (progressive and non-progressive). In six (60%) of the included articles, a positive relationship between adherence to the Mediterranean diet and semen quality was demonstrated; in two (20%) of the articles, no association was found; and finally, in two (20%) of the included articles, the relationship between dietary patterns typical of DM and semen quality was evaluated. Dietary habits influence semen quality. Adherence to the Mediterranean diet can improve male reproductive health, as it is a diet with antioxidant and anti-inflammatory effects. This is the first systematic review about the influence of the Mediterranean diet on semen quality, and the results are positive. These findings may allow us to provide better advice to our patients and to establish interventions with the aim of improving the results of assisted reproduction techniques.
RESUMO
BACKGROUND: Nowadays, there is a growing interest in the relationship among lifestyle, reproductive health, and fertility. Recent investigations highlight the influence of environmental and lifestyle factors such as stress, diet, and nutritional status on reproductive health. The aim of this review was to determine the influence of nutritional status on ovarian reserve in order to improve the reproductive health of women of childbearing age. METHODS: A systematic literature review was carried out following the PRISMA method. The quality of the studies was assessed using the Cochrane Collaboration Risk of Bias tool. Data were extracted, and the results were summarized into two blocks: according to the technique used to assess ovarian reserve and nutritional status; according to the results found in the relationship between ovarian reserve and nutritional status. RESULTS: A total of 22 articles involving 5929 women were included. In 12 of the included articles (54.5%), a relationship between nutritional status and ovarian reserve was demonstrated. In seven publications (31.8%), the increased body mass index (BMI) led to a decrease in ovarian reserve, two of them (0.9%) in patients with polycystic ovary syndrome, showing a decrease only if BMI > 25. In two articles (0.9%), there was a negative relationship between ovarian reserve and waist-to-hip ratio, and in one (0.45%), a positive relationship was shown between ovarian reserve and testosterone levels, the latter being related to body mass index. In five articles (22.7%), body mass index was used as a confounder and was negatively related to ovarian reserve, and in another four (18%), no correlation was found. CONCLUSIONS: Ovarian reserve appears to be influenced by nutritional status. A high body mass index has a negative impact on the ovary, decreasing antral follicle count and anti-Müllerian hormone. Oocyte quality is compromised, increasing the rate of reproductive problems and the demand for assisted reproductive techniques. Further studies are needed to understand which dietary factors have the greatest effect on ovarian reserve in order to promote reproductive health.

INTRODUCCIÓN: Los miomas uterinos son la tumoración pélvica más frecuente en la mujer en edad reproductiva. Aunque existen múltiples tratamientos quirúrgicos, radiológicos y médicos, las técnicas que garanticen la fertilidad posterior de las pacientes son limitadas. CASO CLÍNICO: En nuestro centro, una mujer de 36 ańos sana nuligesta con útero miomatoso se sometió a miomectomía por radiofrecuencia. La paciente quedó gestante 10 meses tras la intervención y la gestación cursó con normalidad. Llegando a término, finalizó la gestación mediante parto vaginal sin incidencias. DISCUSIÓN: El caso presentado apoya a la miomectomía por radiofrecuencia como alternativa de tratamiento segura para pacientes útero miomatoso con deseo genésico posterior
INTRODUCTION: Uterine fibroids are the most common pelvic tumor in women of reproductive age. Although there is a wide variety of surgical, radiological and medical treatments, techniques that preserve efficiently the fertility are limited. CASE REPORT:A 31-year-old nuligravid woman with uterine fibroids underwent a radiofrequency myolysis in our Center. Ten months after the procedure, she became pregnant and had a vaginal delivery without complications during pregnancy or delivery. DISCUSSION: Radiofrequency myolysis could be an alternative treatment for patients with uterine fibroids who desire to preserve their fertility
