Energy metabolism and the evolution of reproductive suppression in the human femaleGrazyna Jasienska
Department of Anthropology, Harvard University, Cambridge, USA
Acta Biotheor 51:1-18. 2003..A reproductive suppression occurring in low energy availability situations may thus represent an adaptive rather then a pathological response...- High tea consumption diminishes salivary 17beta-estradiol concentration in Polish womenMaria Kapiszewska

Br J Nutr 95:989-95. 2006..02). Women with high consumption of tea had lower levels of E2 concentration throughout the entire menstrual cycle.

Reproduction and lifespan: Trade-offs, overall energy budgets, intergenerational costs, and costs neglected by researchGrazyna Jasienska
Department of Epidemiology and Population Studies, Jagiellonian University, Krakow, Poland
Am J Hum Biol 21:524-32. 2009..4) Costs of reproduction are related not only to having children but also to having grandchildren.

Cancer Epidemiol Biomarkers Prev 15:2131-5. 2006..01) and 52 % higher compared with A1/A2 (P = 0.03). Our results suggest that CYP17 genotype may serve as a biomarker of endocrine function in women of reproductive age. (Cancer Epidemiol Biomarkers Prev 2006;15(11):2131-5)... - Fatness at birth predicts adult susceptibility to ovarian suppression: an empirical test of the Predictive Adaptive Response hypothesisGrazyna Jasienska

Proc Natl Acad Sci U S A 103:12759-62. 2006..We suggest that the amount of activity necessary to reduce levels of estrogen, which may in turn reduce cancer risk, can depend on a woman's nutritional status at birth... - Large breasts and narrow waists indicate high reproductive potential in womenGrazyna Jasienska
Department of Epidemiology and Population Studies, Jagiellonian University, Grzegorzecka 20, 31 531 Krakow, Poland
Proc Biol Sci 271:1213-7. 2004..Such gains in hormone levels among the preferred mates may lead to a substantial rise in the probability of conception, thus providing a significant fitness benefit... - Energetic factors, ovarian steroids and the risk of breast cancerG Jasienska

Department of Epidemiology and Population Studies, Jagiellonian University Collegium Medicum, Krakow, Poland
Womens Health Issues 15:145-51. 2005..Further, because estrogen levels in postmenopausal women positively correlate with body fat, we hypothesize that there is an inverse relationship between body fat and depressive symptoms among postmenopausal women... - Energetic factors and seasonal changes in ovarian function in women from rural PolandGrazyna Jasienska

Am J Hum Biol 21:520-3. 2009..In conclusion, parity caused a slightly higher body mass and BMI later in life. However, parity did not lead to covert maternal depletion, perhaps because women in this population have relatively high-dietary intake of PUFAs... - Women's preferences for sexual dimorphism in height depend on menstrual cycle phase and expected duration of relationshipBoguslaw Pawlowski

Am J Hum Biol 18:710-3. 2006..24, P = 0.05; r(2) = 0.25, P = 0.04, respectively). We propose that, contrary to popular understanding, a thicker endometrium suggests greater iron reserves, rather than greater risk for anemia, in healthy women...
