But there's no clinical data supporting the fact that yoga increases conception rates.
Increased conception rates after calving, and, as consequence, decreased CI may also reflect fertilization ability of bulls in the studied population.
(Participant 9) Prior experiences with pain and doctors combined with expectations about going through pregnancy also increased conception anxiety related to infertility and speculum exams.
Moreover, the longest delay in reaching an estrous cow is reduced from 7.6 to 5.9 h (i.e., by 1.7 h), which may increase the conception ratio by some 7%.
Prior pregnancy did not increase postoperative conception in this study.
Only three publications explicitly stated that the service was available for non-pregnant women [ 17, 25, 29], with only one program stating goals to improve the pre-conception health of women and increase pre-conception immunisation [ 37].
30 Overall, the results suggested that both individual/couple and group interventions were effective in reducing emotional distress as well as increasing the conception rate.
It has been established that obesity is associated with decreased natural fecundity, a decreased ovulation rate, increased time until conception, and increased rates of miscarriage [ 4, 5].
As long ago as 1955, Kerruish reported that insemination centres for cows did not provide "adequate sexual stimulation" prior to semen collection: his regimen of intensive sexual stimulation resulted in a "marked improvement in sexual behaviour" and – crucially for our question – an increase in the conception rate.
Thus, while knowledge increase and alternative conception decrease were notable outcomes of our intervention, and many others in the literature, teachers' abilities to communicate robust explanations of evolutionary change were modest.
