There is a traditional believe that if premenopausal women engage in prolonged physical exercise, they are likely to have infertility. This study assessed the effect of prolonged moderate – vigorous exercise on ovarian reserve and ovulatory status in premenopausal students of Nnamdi Azikiwe University, Nnewi Campus. The objectives were to determine the effect of moderate – vigorous intensity exercise on Anti-Mullerian hormone (AMH), day 3 Follicle stimulating hormone (FSH), Luteinizing Hormone (LH), day 3 Estrogen, day 21 Estrogen, and day 21 Progesterone levels in premenopausal women. This was a prospective comparative study involving 80 participants aged between 19 and 25 years, randomly selected and assigned to exercise group and control group. The exercise group comprised 40 participants who engaged in moderate – vigorous intensity exercise using elliptical bike for 30 minutes, five days a week for 3 months; however, 30 individuals completed the exercise. The control group comprised of 40 individuals that did not do exercise but 30 individuals completed the study. Blood (8ml) was collected from each of the participants at baseline, 1 month, 2 months, and 3 months. AMH, FSH, LH, Estrogen and Progesterone levels were analyzed using enzyme- linked Immunosorbent assay (ELISA) method. Results were regarded as significant at p˂ 0.05. In the exercise group, the serum level of day 3 FSH, LH, Estrogen were significantly lower from 7.27±0.77 mIU/ml, 7.00±0.77 mIU/ml, 36.33±5.13 pg/ml respectively at baseline to 5.62±0.48 mIU/ml, 5.36±0.80 mIU/ml, 21.36±4.34 pg/ml respectively after 3 months of exercise while there was significantly higher levels of AMH and day 21 progesterone after 3 months of exercise compared with the baseline and respective control (p<0.05). Prolonged Moderate-to-vigorous exercise may enhance fertility and well-being of premenopausal women. Key words: Anti-Mullerian hormone (AMH), day 3 Follicle stimulating hormone (FSH), Luteinizing Hormone (LH), day 3 Estrogen, day 21 Estrogen, day 21 Progesterone, moderate – vigorous exercise, ovarian reserve, ovulatory status, premenopausal women.

Chronic heart failure is one of the leading causes of death globally, affecting 1.5 to 2% of the total world population and 2.9 to 3.9% of the total Western European population. Chronic heart failure often progresses rapidly in coexistence with endocrine pathology, namely hypothyroidism, that results in a more rapid development and further progression of endothelial dysfunction and the development of a systemic inflammatory response. The aim of our research was to study the levels of endothelin-1, C-reactive protein, tumor necrosis factor α and their correlation with the levels of thyroid-stimulating hormone, thyroxine in patients with chronic heart failure and coexisting hypothyroidism. There were examined 38 patients with chronic heart failure and coexisting hypothyroidism and 42 patients with chronic heart failure without hypothyroidism. The serum levels of endothelin-1, C-reactive protein, tumor necrosis factor α were determined by the enzyme-linked immunosorbent assay, while the levels of thyroid-stimulating hormone and thyroxine were determined by the electrochemiluminescence immunoassay. In patients with chronic heart failure and coexisting hypothyroidism, the levels of endothelin-1, C-reactive protein, and tumor necrosis factor α were 2.9, 1.5 and 2.27 times higher than those in patients without hypothyroidism. In Group I, there was a moderate positive correlation between the serum levels of endothelin-1 and thyroid-stimulating hormone and a weak negative correlation between the levels of thyroxine and endothelin-1. In Group II, there was a weak correlation between the levels of endothelin-1 and thyroid-stimulating hormone and no correlation between the levels of thyroxine and endothelin-1. In Group I, there was a strong positive correlation between C-reactive protein and thyroid-stimulating hormone levels as well; in Group II, no similar correlation was found. In Group I, there was found a moderate negative correlation between tumor necrosis factor α and thyroxine levels. According to our results, there was a close correlation between the markers of endothelial dysfunction, immune inflammatory response, and single markers of hypothyroidism.

Background: Sarcopenia is a geriatric syndrome characterized by progressive loss of muscle mass, function and quality and associated with a range of adverse health outcomes including disability. Despite a negative correlation between muscle mass and follicle-stimulating hormone (FSH) levels in postmenopausal women, it is unclear if FSH is associated with sarcopenia and its poor outcomes, especially in older men.Methods: We used cross-sectional data from 360 men aged over 80 who participated in health check-ups to investigate correlations between serum FSH and sarcopenia, individual sarcopenia components, low physical performance (gait speed ≤ 0.8 m/s) and instrumental activities of daily living (IADL) disability. Sarcopenia and severe sarcopenia were diagnosed according to the revised definition of the European Working Group on Sarcopenia in Old People (EWGSOP2).Results: The prevalence of sarcopenia was 17.8% in this population. In binary logistic regression analysis, compared with higher FSH group, lower FSH group showed a significant reduction in the risk of low calf circumference (a surrogate for muscle mass; OR 0.308, 95% CI 0.109–0.868, P = 0.026) after adjusting potential confounders including age, waist circumference, education, exercise, associated biochemical parameters, other sex hormones and high-sensitivity C-reactive protein. The correlation between FSH and low handgrip strength was marginally significant (OR 0.390, 95% CI 0.151–1.005, P = 0.051). No associations were observed between FSH and sarcopenia, severe sarcopenia, and disability in adjusted models.Conclusion: In older men, circulating FSH was not associated with sarcopenia, sarcopenia severity, the majority of its components and adverse health outcome (IADL disability), with the exception of low calf circumference. Further work is needed to better elucidate the association of FSH and low muscle quantity by adopting more accurate measurement method of appendicular skeletal muscle mass such as DXA, CT or MRI.

The objective of the study was to assess the association between changes in plasma follicle-stimulating hormone (FSH) and the potential effect on idiopathic pulmonary arterial hypertension (IPAH) in male patients. A total of 116 male patients with IPAH and 53 healthy controls were included from XX Hospital. Plasma FSH concentration was assessed in all participants. Receiver operating characteristic curves were used to assess the mortality risk. Kaplan–Meier curve and Cox regression analyses were used to predict the value of FSH on the survival rate of male IPAH patients. The plasma FSH concentration in the IPAH group was significantly higher than that in the control group ( p = .017). Nonsurvivors had significantly higher levels of FSH than survivors ( p < .0001). FSH levels were positively correlated with World Health Organization Functional Class, mean pulmonary artery pressure, and pulmonary vascular resistance (PVR; p = .023, p < .0001, and p < .0001, respectively) and negatively correlated with 6-min walk distance (6MWD) and cardiac output (CO; p = .004 and p = .010). Cox regression model analysis showed that the levels of FSH were also the independent factors of mortality in male IPAH patients ( p < .0001). The IPAH patients with higher FSH levels had higher PVR, lower 6MWD, CO, and a lower survival rate ( p = .042, p = .003, p = .029, and p < .0001, respectively). Therefore, we identified that increased FSH levels were associated with disease severity in male patients with IPAH and independently predicted risk of disease and poor survival rate.

Recombinant human follicle stimulating hormone (r-hFSH) is widely used for infertility treatment and is subject to the development of biosimilars. There are different purification strategies that can yield r-hFSH of pharmaceutical quality from Chinese hamster ovary cell culture broth. We developed a purification process for r-hFSH centered on immunoaffinity chromatography with single-domain recombinant camelid antibodies. The resulting downstream process is simple and devoid of ultrafiltration operations. Studies on chromatography resin resource and ligand leakage showed that the immunoaffinity matrix employed was suitable for industrial use and stable for at least 40 full chromatography cycles, and the leaked single-domain antibody ligand was completely removed by subsequent purification steps. All chromatography resins employed withstood the same 40 cycles of use without significant changes in separation efficiency and product binding capacity. The resulting industrial purification process yielded batches of r-hFSH with consistent levels of purity and bioactivity.
