The advantages of collaborative design include reducing the costs of new product conception, reducing research time, and enhancing competitive power (Huang et al. 2003).
Supplementation with FA before the time of conception reduces the risk of NTDs.
The Eastern region also has the highest median duration of exclusive breastfeeding compared to the rest of the country which prolongs lactational amenorrhea and thereby delays conception, reducing the time of exposure to pregnancy [ 14].
A strong evidence base has been established, indicating that the consumption of folic acid supplements, for a period of about three months prior to conception, reduces by two thirds the risk of neural tube defects [ 1].
Early development affects the trajectory of this risk, thus a focus on health before conception reduces NCD risk in both the mother and her children (based on Godfrey et al., 2010 [ 19] and Sattar and Greer, 2002 [ 43].
Our population based study shows that fortification of grain products with folic acid in Canada was followed by a significant decrease in the birth prevalence of severe congenital heart defects, supporting the hypothesis that folic acid intake in the period around conception reduces the birth prevalence of severe congenital heart defects.
Folic acid intake around the time of conception reduces the risk of neural tube defects in the newborn. 1 2 3 Measures to increase intake of folic acid in this period include multivitamin supplementation 4 and fortification of grain products such as flour and pasta.
Generally, after the age of 30 a woman's chance of conception reduces by 3-5% everyearar, with a considerably higher reduction after 40.
This study was undertaken to ascertain whether the incidence of pregnancy is increased and time-to-conception is reduced in infertile women with rectovaginal endometriosis undergoing conservative surgery compared with those on expectant management.
49 Psychological stress related to severe life events (eg, a cancer diagnosis) around the time of conception may reduce the male proportion of newborns through differential conception or differential abortion of male embryos.
