To evaluate whether DNA fragmentation and/or mitochondrial membrane potential (MMP) predict natural conception better than standard sperm parameters.
To evaluate whether sperm DNA fragmentation (sDF), measured in brighter, dimmer, and total populations, predicts natural conception, and to evaluate the intra-individual variability of sDF.
Mean percent fruit in the diet significantly predicts chimpanzee waiting time to conception (Emery Thompson and Wrangham 2008); thus, fruit availability may similarly predict waiting time to conception in Bornean orangutans.
DESIGN, SETTING, AND PARTICIPANTS: We built four prognostic models from a large multicenter randomized controlled infertility trial of 626 women with PCOS performed at academic health centers in the United States to predict success of ovulation, conception, pregnancy, and live birth, evaluating the influence of patients' baseline characteristics.
Logistic regression was used to assess whether biochemical and psychological measures of stress can predict whether a subsequent conception will occur.
History of a prior loss predicted ovulation and conception, but not pregnancy or live birth.
Previous studies demonstrated significant cohort heterogeneity in terms of mother-offspring vs father-offspring telomere length correlations (Eisenberg, 2014), however, it is now well established that paternal but not maternal age at conception predicts offspring telomere length (Broer et al., 2013).
As developmental programming can begin before conception, pre-gravid factors that predict birthweight may be relevant in this context.
A modified Ferriman Gallwey hirsutism score of less than 8 was predictive of conception, pregnancy, and live birth (although it did not predict ovulation success).
Other apps predict a baby's gender from the date of conception, or peddle other pseudoscientific claims.
