Abstract: BY MARION BARCLAY R. K. BARCLAY V. P. SKIPSKI OLGA TEREBUS-KEKISH C. H. MUELLER ELLEN SHAH AND W. L. ELKINS* Division of Experimental Chemotherapy Sloan-Kettering Institute for Cancer Research Rye N. Y. and Sloan-Kettering Division Graduate School of Medical Sciences Cornell University Medical College New York 21 N. Y. U.S.A. 1. Lipoproteins were measured in sera from 11 young women having a similar environment and diet. Sera were obtained at weekly intervals over a 12-week period. The values of the lipoproteins during periods in the normal ovulatory cycle were compared to assess their relation to reported hormone concentrations in blood. 2. Only the 4-0sf (HDL2) (d 1·125 sodium chloride) fraction changed significantly ; it increased at ovulation in ten of the 11 subjects and fell as menstruation approached. 3. There was greater variability in most of the low-density rather than the highdensity lipoproteins within individuals. The lipoprotein class most characteristic for an individual was the 4-Osf or HDL2 fraction. The influence of sex hormones an serum lipoproteins was first demonstrated by Gofman et al. (1950). They observed lower quantities ... schö
