ABSTRACT
Fourteen infertile males (age 24-45 years; married over 2 years) with idiopathic oligospermia (sperm count less than 40 millions/ml) were investigated for the effect of oral zinc sulphate (220 mg) for 4 months on their serum and seminal zinc levels, and seminal parameters. With zinc administration serum zinc levels remained essentially unaffected, however, seminal zinc levels increased significantly. There was significant improvement in sperm count, number of progressively motile and normal spermatozoa, and acid phosphates activity. Wives of 3 patients conceived. Observations suggest that zinc has potential to be used in male infertility. However, further studies are warranted.

Various lung volumes and ventilatory tests (TV, ERV, IC, MV, MVV, VC, FEV1, MMFER and PEFR) were determined and BR, DI and AVI (Air velocity Index) calculated in 241 Rajasthani subjects of either sex ranging from 17 to 40 years of age. Most of the values (Mean +/- SEM) are higher in males than in females, and also higher in the younger age groups (17 to 27 years) than in the older age groups (28 to 40 years) for the same sex.
