Rabbit Anti-Human IHH (internal) Polyclonal antibody

A multicenter, open-label, randomized, controlled superiority trial with 18 months of follow-up was conducted to investigate whether oral zinc supplementation could further promote spermatogenesis in males with isolated hypogonadotropic hypogonadism (IHH) receiving sequential purified urinary foil icular-stimulating hormone/human chorionic gonadotropin (uFSH/hCG) replacement. Sixty-seven Chinese male IHH patients were recruited from the Departments of Endocrinology in eight tertiary hospitals and randomly allocated into the sequential uFSH/hCG group (Group A, n = 34) or the sequential uFSH plus zinc supplementation group (Group B, n = 33). In Group A, patients received sequential uFSH (75 U, three times a week every other 3 months) and hCG (2000 U, twice a week) treatments. In Group B, patients received oral zinc supplementation (40 mg day(-1)) in addition to the sequential uFSH/hCG treatment given to patients in Group A. The primary outcome was the proportion of patients with a sperm concentration >= 1.0 x 10(6) ml(-1) during the 18 months. The comparison of efficacy between Groups A and B was analyzed. Nineteen of 34 (55.9%) patients receiving sequential uFSH/hCG and 20 of 33 (60.6%) patients receiving sequential uFSH/hCG plus zinc supplementation achieved sperm concentrations >= 1.0 x 10(6) ml(-1) by intention to treat analyses. No differences between Group A and Group B were observed as far as the efficacy of inducing spermatogenesis (P = 0.69). We concluded that the sequential uFSH/hCG plus zinc supplementation regimen had a similar efficacy to the sequential uFSH/hCG treatment alone. The additional improvement of 40 mg day(-1) oral zinc supplementation on spermatogenesis and masculinization in male IHH patients is very subtle.

Background: it is vital to monitor and promote healthy lifestyle habits in early adolescence, as it is a time of changes when future lifestyle habits are formed. Methods: a study was conducted to find out the effects of a Healthy Habits Program (HHP) in children between the ages of 10 and 12 years (N=158). The study included an intervention group (IG) (n=90), which participated in the BHP for 8 months, and a control group (CG) (n=100). In order to assess healthy habits in these children we used the Inventory of Healthy Habits (HIM, the reliability of which was previously evaluated (N=134). Results: the IHH obtained good reliability, Interclass Correlation Coefficient (range.506-884; p<.001) and Spearman Correlation Coefficient (range r=529-884; p<.001). As regards the IMP, there were no differences in eating habits initially (p=.564), but by the end of the study (p=.001) the IG showed better habits. As for the other healthy habits indicators, the CG had better habits initially (p=.047), but the score of the IG improved and there were no differences between the groups at the end of the study. Conclusions: it was shown that the Hill is a suitable and reliable questionnaire for studying habits in adolescents. The HEW brought about changes in the IG, which achieved better scores for eating habits and sum of health habits.
