Background/Objective: The aim of this study was to outline the relationships between selected parameters connected with lifestyle and serum anti-Müllerian hormone (AMH) levels, i.e., a marker of ovarian reserve. By examining AMH levels in connection with nutrient intake and body composition parameters, this study aimed to provide a preliminary background for further studies focused on establishing dietary and lifestyle recommendations that could lead to improvements in fertility outcomes. Methods: The research involved 28 women, aged 26 to 42—both with and without ovulatory infertility—who were patients of the Reproductive Health Clinic at the Medical University of Białystok. The participants underwent a number of tests consisting of hormonal profiling, including AMH measurements, body composition analyses, and dietary assessments based on a 3-day food diary. Results: The findings of the study indicate that certain lifestyle factors are associated with changes in AMH levels. Most importantly, the multivariate linear regression model designed in the study shows that age, waist-to-hip ratio (WHR), as well as the intake of sucrose, iodine, and erucic acid explain variations in serum AMH levels. These results support the hypothesis that modifiable lifestyle factors can influence AMH levels, and thus ovarian reserve. Conclusions: The study underscores the potential for targeted lifestyle interventions to support fertility and calls for further research in the form of prospective studies performed in larger groups of patients to substantiate these associations and inform fertility care strategies. Based on the preliminary results of this study, certain dietary ideas that could positively influence fertility have been proposed, focused on the normalization of body weight and the reduction in excess fat tissue.

Background: Asprosin is a relatively recently discovered glucogenic adipokine secreted during fasting that plays an important role in various biochemical processes in the body, including those connected with obesity and insulin resistance. The aim of this exploratory study was to investigate the associations between selected hormonal, anthropometric, and lifestyle-related parameters and serum asprosin concentration. As studies concerning fertility and asprosin have so far been limited to men or women with PCOS, its role in the general female population remains largely unexplored. The direction of this exploration was thus pointed toward possible connections with female fertility. Methods: The case-control study group included 56 women of reproductive age (25–42 years), who were patients of the Reproductive Health Clinic and the Clinic of Endocrinology, Diabetology, and Internal Medicine of the Medical University of Białystok, Poland. The levels of selected hormones, including anti-Müllerian hormone (AMH), estradiol, sex hormone-binding globulin (SHBG), and testosterone, body composition parameters, and a lifestyle parameter—night fasting duration—were assessed to test their associations with serum asprosin concentration. Results: A weak negative correlation was found between AMH level and serum asprosin concentration, suggesting a potential link between asprosin and ovarian reserve. Furthermore, a moderate positive correlation was found between the percentage of total body water (TBW) and serum asprosin concentration. No significant associations were observed between the levels of the other tested hormones and serum asprosin concentration, or between body composition parameters or night fasting duration and serum asprosin concentration. The multivariate model designed in the study shows that AMH, TBW, and night fasting duration explain 23.4% of asprosin variability. Conclusions: Although the nature of the study is exploratory, the findings indicate that the role of asprosin in the female population—particularly its role in fertility—requires further research. Not only is the number of available studies on asprosin insufficient, but the results of this study partly contradict what is known about the hormone from previous studies, which were largely performed with male cohorts. In addition, the results of this study suggest that asprosin may indeed be involved in mechanisms related to female fertility, particularly those connected with ovarian reserve. Nevertheless, studies performed in larger, more homogeneous populations are necessary to confirm the role of asprosin in women, including its association with female fertility.
