Circulating leptin during ovine pregnancy in relation to maternal nutrition, body composition and pregnancy outcome.
This study examined the pattern of circulating leptin in age-matched sheep during adolescent pregnancy, and its relationship with maternal dietary intake, body composition and tissue expression of the leptin gene. Overfeeding the adolescent pregnant ewe results in rapid maternal growth at the expense of the placenta, leading to growth restriction in the fetus, compared with normal fed controls....
متن کاملSerum Phthalate Levels and Time to Pregnancy in Couples from Greenland, Poland and Ukraine
Phthalates are ubiquitous industrial chemicals that have been associated with altered reproductive function in rodents. Several human studies have reported an inverse association between male testosterone and phthalate levels. Our aim was to investigate time to pregnancy (TTP) according to serum levels of diethylhexyl phthalate (DEHP) and diisononyl phthalate (DiNP) metabolites in both partners...
متن کاملPerfluoroalkyl substances and time to pregnancy in couples from Greenland, Poland and Ukraine
BACKGROUND Perfluoroalkyl substances (PFAS) are suggested to affect human fecundity through longer time to pregnancy (TTP). We studied the relationship between four abundant PFAS and TTP in pregnant women from Greenland, Poland and Ukraine representing varying PFAS exposures and pregnancy planning behaviors. METHODS We measured serum levels of perfluorooctanoic acid (PFOA), perfluorooctane su...
متن کاملBasal body temperature assessment: is it useful to couples seeking pregnancy?
Advanced practice nurses in primary care settings are often asked to give appropriate advice to couples seeking pregnancy. This article examines the issue of basal body temperature (BBT), a time-honored way to establish the presence of ovulatory cycles, and asks if BBT is an outdated recommendation. The article also reviews the benefits and limitations of recommending BBT to couples seeking pre...

The weights of some organs and tissues increase whereas others decrease and there is considerable variation in the magnitude of these changes (Hytten & hi tch , 1971). For interspecies comparisons the enormous differences in the quantitativ...
