Male fertility, a generally overlooked aspect in studies of human reproductive patterns, is examined from the reproductive life histories of Chamorro males with essential completed fertility by 1941. Males in this “natural fertility” indigenous population of the Pacific island of Guam exhibit low levels of couple infertility which are counteracted by high levels of adult male mortality, while new unions formed after the death of female partners t…

On Treponemal Disease in the Western Pacific
Coital rates, sex‐selective infanticide, and sex ratios at birth
In response to Jamess remarks concerning their article on sex ratios in Micronesia the authors reply that there is no evidence that sex-selective infanticide was ever practiced by the native populations of Butaritari and Guam. There is ample historical and ethnographic evidence to the contrary in the Mariana Islands and Butaritari. Historical accounts begin in 1602 with the comments of Fray Juan Pobre de Zamora who observed the exceptional affect…
Maternal/offspring birth month concordance in a Pacific island population
Analyses of 13,863 births occurring on Guam before 1942 reveal statistically significant concordance of maternal and offspring birth months, accounting for over 17% of recorded births. A secular change by maternal birth year in month of highest concordance level coincides with changing public health measures over this historical period. Together with observed birth order effects, showing decreasing concordance values with increasing birth order r…
Sex ratio of livebirths in Micronesia
A growing body of data extends Hunt's earlier findings from Yap to suggest a characteristic Micronesian pattern of highly masculinized secondary sex ratios. Using materials from an extensive family record register for pre–World War II Guam, it is now possible to examine parental age and birth order effects in a Micronesian population in which the overall sex ratio of livebirths to 3,406 formally wed and fertile couples was 109.6. In contrast to t…
Sex ratios at birth in Micronesia
In response to comments of William H. James on the authors' articles, it is stated that Micronesian populations are now and have been in the past characteristically highly masculinized at birth (i.e., secondary sex ratios [SSR] of over 108-110). It is fascinating to examine how this finding may reflect microevolutionary change in this island setting. Aspects of reproductive behavior in Micronesia were examined for clues to proximate/remote mechan…
Secondary Sex Ratios in Micronesian Populations
Secondary sex ratios in Micronesian populations
Secondary sex ratio (SSR) values in excess of 109 male for every 100 female livebirths have been reported from several Micronesian populations. Analyses of linked family records dating from before 1942 for the native people of Guam reveal a highly masculinized SSR even at high birth orders and parental ages of married fertile couples. These findings contrast with reported declines in SSR with parity and parental age among historical and modern po…
Seasonally of vital events in a pacific island population
Analyses of vital data derived from a family record register for the native population of Guam reveal significant variations in births, deaths, and marriages over the period 1901-41. Although lacking marked photoperiod or temperature changes of temperate zones, the tropical island is subject to marked seasonal differences in rainfall characteristic of western Pacific islands. Marital patterns exhibit troughs associated respectively with the Lente…
