There is demographic evidence from studies in the Andes (James, 1966; Heer, 1967; Abelson, 1976) for lower fertility in high-altitude dwellers than in moderate- or low-altitude dwellers. In the Sherpas of Nepal, the completed fertility rate at high altitude (about 6·0) is appreciably less than that at lower altitudes (8·5; C. R. M. Bangham & J. M. Sacherer, unpublished observations). However, the physiological reasons (if any) for such a difference are obscure. The present study was carried out to test the hypothesis that such a fertility difference (between low- and high-altitude dwellers) is reflected in different serum concentrations of reproductive hormones.
Sampling was carried out at altitudes of 4240 m in Khumbu, 2670 m in Pharak (south of Khumbu) and 1460 m in Kathmandu; the
