  • Proximate determinants of fertility in Ethiopia; an application of revised Bongaarts model. [Journal Article]
    Reprod Health 2019; 16(1):13Laelago T, Habtu Y, Yohannes S
  • CONCLUSIONS: Among the four proximate determinants of fertility, the contribution of index of marriage was the highest in inhibiting fertility in 2011. On the other hand, the contribution of postpartum infecundability was the highest in inhibiting fertility in 2016. The contribution of the index of contraceptive in inhibiting fertility increased from 28.5% in 2011 to 30.7% in 2016. The index of foetal wastage contributed the least in both 2011 and 2016 survey years. Therefore, strategies have to be designed to promote the contraceptive use and breast feeding practices among the reproductive women.
  • Race, Remarital Status, and Infertility in 1910: More Evidence of Multiple Causes. [Historical Article]
    Demography 2017; 54(5):1949-1972London AS, Elman C
  • The dominant approach to studying historical race-related fertility differences has been to limit samples to first-married and younger women. We argue that studying historical race-related fertility differences in the context of remarriage is also important: remarriage and fertility patterns are both rooted in the biosocial conditions that produce racial disparities in health. We employ a multipl…
  • Somatic symptoms, sleep disturbance and psychological distress among women undergoing oocyte pick-up and in vitro fertilisation-embryo transfer. [Journal Article]
    J Clin Nurs 2016; 25(11-12):1748-56Lin YH, Chueh KH, Lin JL
  • CONCLUSIONS: Sleep disturbance was the most significant factor involved in the psychological distress of women having problems with conception.Assisted reproductive technologies nurses can assess women's psychological distress by caring for their sleep disturbance without directly exploring their mood state. Moreover, these medical personnel should understand infertile female patients' psychological distress is mainly associated with their sleep disturbance. Developing various strategies to improve both sleep quality and psychological distress for infertile female patients should be recognised in future studies.
  • Consequences of infertility in developing countries. [Review]
    Perspect Public Health 2013; 133(3):174-9Rouchou B
  • Infertility affects more than 10% of the world's population. In developing countries, there are severe social, psychological and economic consequences for infertile men and women. All of the cited references are compiled from primary peer-reviewed research articles that were conducted through one-to-one interviews or focus groups in countries of developing regions, such as Africa, Asia and the Mi…
  • Offspring: Human Fertility Behavior in Biodemographic Perspective [BOOK]
    National Academies Press (US): Washington (DC) National Research Council (US) Panel for the Workshop on the Biodemography of Fertility and Family Behavior Wachter Kenneth W KW Bulatao Rodolfo A RA BOOK
  • This volume explores the relevance of new developments in biology, genetics, and evolutionary anthropology to our understanding of human fertility behavior and family formation, under the rubric of “biodemography.” The biology of fecundity, infecundity, and contraception has long been integral to human population studies. But demographers are only beginning to assimilate findings and approaches f…
  • A coevolutionary arms race causes ecological speciation in crossbills. [Journal Article]
    Am Nat 2007; 169(4):455-65Smith JW, Benkman CW
  • We examined three ecological factors potentially causing premating reproductive isolation to determine whether divergent selection as a result of coevolution between South Hills crossbills (Loxia curvirostra complex) and Rocky Mountain lodgepole pine (Pinus contorta latifolia) promotes ecological speciation. One factor was habitat isolation arising because of enhanced seed defenses of lodgepole p…
  • Paternal age: are the risks of infecundity and miscarriage higher when the man is aged 40 years or over? [Review]
    Rev Epidemiol Sante Publique 2005; 53 Spec No 2:2S47-55De La Rochebrochard E, Thonneau P
  • CONCLUSIONS: The risks of infecundity and miscarriage increase with paternal age. Two main hypotheses can be considered. First, these risks increase after the age of 35-40 years. However, a later paternal age effect (after 45-50 years) cannot be excluded. Second, due to the interaction of the ages of the two partners, the risks of infecundity and miscarriage may be higher when both partners are older (woman aged 35 years or over and man aged 40 years or over).
