Effect of Ramadan fasting on secretion of sex hormones in healthy single males
Mesbahzadeh, B.; Ghiravani, Z.; Mehrjoofard, H. ( 2005 )
Abstract

To determine the effects of Ramadan fasting on the secretion of sex hormones in single healthy males, we measured blood hormone levels of testosterone, luteinizing hormone [LH] and follicle-stimulating hormone [FSH] in 52 single male students aged 18-24 years who were fasting for >/= 12 hours during Ramadan. Four blood samples were taken from each, one 2 days before and the others on 10, 20 and 28 Ramadan. Testosterone level was lower, significantly so for the 20th and 28th of the month [P < 0.05]; FSH was increased, significantly for the 20th [P < 0.05]; LH did not change significantly

[Food intake, and anthropometrical and biological parameters in adult Tunisians during Ramadan]
Beltaifa, L.; Bouguerra, R.; Ben Slama, C.; Jabrane, H.; El Khadhi, A.; Ben Rayana, M.C.; Doghri, T. ( 2002 )
Abstract

We evaluated the effects of fasting during Ramadan on nutritional intake and plasma lipoproteins in 20 healthy adults of normal weight. A 5-day food questionnaire was completed for every participant. Clinical investigations, anthropometrical measurements and laboratory analysis were also undertaken. Body weight, blood pressure and blood glucose were not influenced by fasting but there were non-significant modifications in the plasma lipid fractions. The total cholesterol remained unchanged. Total daily energy intake was comparable before, during and after Ramadan despite the decrease in meal frequency during fasting. Thus fasting in Ramadan did not affect dietary intake, clinical, anthropometrical and most biological parameters

Predicting serum gastrin levels among men during Ramadan fasting
Nomani, M.Z.A.; Khan, A.H.; Shahda, M.M.; Nomani, A.K.; Sattar, S.A. ( 2005 )
Abstract

Increased gastric acidity is common when fasting during Ramadan. Our study aimed to develop a regression equation to predict fasting serum gastrin levels using parameters commonly analysed in clinical laboratories. Fasting blood samples from six men were taken on days 1, 10, 19, 26 and 28 of Ramadan. Serum gastrin, total cholesterol, urea and uric acid were analysed. All 5 samples from each man were included in multiple regression analysis and the prediction equation obtained was: serum gastrin, pg/mL = 198.27-0.199 total cholesterol [mg/dL] + 2.525 urea [mg/dL]--103.238 uric acid [mg/dL] + 10.923 uric acid [mg/dL]2 + 3.683 body mass index, r2 = 0.75, P < 0.001. This equation might be used to estimate gastrin levels and plan dietary and medicinal measures to avoid high gastric acidity during Ramadan
