“…9,10 This ovopathy concept is backed by animal experiments on preovulatory and postovulatory overripeness ovopathy and in line with the disproportional excess rates of fatal neural tube defects 11 and type 1 diabetes mellitus, 12 which increase further away from the equator and diverge on both hemispheres. This proposed causal relation of seasonally bound nonoptimally matured oocytes to cancer, therefore, not only agrees with the geographical latitude effect under discussion but also with the disproportional month-of-birth deviations apparent in childhood leukaemia, [13][14][15] premenopausal breast cancer, [16][17][18] lung cancer, 19 and brain tumours in children 20,21 and adults. 22 These deviations in general correspond with the major total birth peak or major ovulatory season.…”

“…Fichera et al 2001), eating disorders (Eagles et al 2001), breast cancer (e.g. Kristoffersen & Hartveit 2000), and allergies (Kusunoki et al 1999). These associations between early conditions and later growth, health and survival have been proposed to result from foetal programming (Lucas 1991), where a stimulus (or lack of stimulus) during a critical period early in life may permanently affect body structure, physiology and metabolism (McCance & Widdowson 1974).…”

Month of birth predicted reproductive success and fitness in pre-modern Canadian women

Conditions experienced during early development affect human health and survival in adulthood, but whether such effects have consequences for fitness is not known. One surrogate for early conditions is month of birth, which is known to influence health and survival in many human populations. We show that in nineteenth century Canada, month of birth predicted a woman's fitness measured by the number of grandchildren produced, with the genetic contribution to the following generations by women born in different months differing by over seven grandchildren. This difference was mainly caused by differences in the reproductive rates of both mothers and their offspring, rather than differences in their survival. Women born in the best months of the year had longer reproductive lifespans, larger numbers of live births and raised more offspring to adulthood than those who were born in the worst months. Furthermore, the offspring of those women born in the best months also had greater reproductive rates, suggesting that month of birth also influenced a mother's ability to invest in her offspring. Our results suggest that early conditions may have important consequences for human lifetime reproductive performance within and between generations, and that timing of birth had large effects on fitness in this rural community.

“…Ellison suggested that levels of ovarian hormonal function in adult women are associated with the tempo of growth and maturation in childhood and adolescence (Ellison, 1996). Other studies demonstrated a relationship between the season of birth and breast cancer, metabolic syndrome and cardiovascular conditions (Kristoffersen and Hartveit, 2000;Tornhammar et al, 2014;Wattie et al, 2008); an early age at menarche increases the risk of all the above diseases. It has also been suggested that there is a connection between birth season and the incidence of endometrial cancer, which may also be indirectly related to the maturation rate (Rowlands et al, 2011).…”

“…Birth month is related to the prevalence of obesity (Phillips and Young, 2000;Tanaka et al, 2007), mental health problems (Joiner et al, 2002), diabetes (Fichera et al, 2001), eating disorders (Eagles et al, 2001), breast cancer (Kristoffersen and Hartveit, 2000), allergies (Kusunoki et al, 1999), and premature mortality (Doblhammer and Vaupel, 2001). Epidemiological studies revealed that the month of birth may also affect life expectancy (Doblhammer and Vaupel, 2001;Lerchl, 2004) and parameters related to reproduction, such as mean offspring count (Huber and Fieder, 2007;Lummaa and Tremblay, 2003;Smits et al, 1997) or age at menopause (Cagnacci et al, 2005).…”
