Women with either resolved or unresolved infecundity were significantly older than fecund women.

It records childlessness, primary and secondary infertility, primary, secondary and self-reported infecundity, and trends in fertility.

Dogmatic constraints, tactical stereotypes, schematism in place of originality, and the boring repetition of truisms are contributing factors in creative infecundity.

It is only that, in seeking to compensate himself for his infecundity, he has fallen into the deep sea of preciosity.

In societies where women breastfeed their babies for up to two years, postpartum infecundity affects fertility levels by delaying the next pregnancy.

Hedonistic dissipation well may have condemned the existing Europeans to infecundity and extinction, but that does not prevent Europe from getting new ones.

In fact, some pro-Israeli writers and analysts have started a campaign in a bid to prove the infecundity of the Two-State solution.

Rather it is one mechanism that increases milk production, thereby increasing the metabolic cost of breastfeeding to mothers, which contributes to sustained infecundity. Suckling as proxy indicator of infecundity rather than a direct, hormonal causal factor is supported in studies contrasting the nursing intensity hypothesis, which says that more intense (prolonged, frequent) breastfeeding will result in a longer period of lactational amenorrhea, and the metabolic load model, which posits that maternal energy availability will be the main factor determining postpartum amenorrhea and the timing of the return of ovarian function.

Amenorrhea itself is not necessarily an indicator of infecundity, as the return of ovarian cycling is a gradual process and full fecundity may occur before or after first postpartum menses. Additionally, spotting or the appearance of first postpartum menses can be a result of either lochia or estrogen withdrawal and not actual ovulation. Lactational amenorrhea has evolved as a mechanisms for preserving the health of the mother. This period of infecundity allows the mother to focus her energy on breastfeeding as well as allow time for her body to heal between births.

Prolactin and oxytocin trigger the release (letdown) of milk and its ejection from the nipple in a positive feedback loop. It was previously thought that prolactin hormone, which is released by the anterior pituitary in response to the direct nerve stimulation of suckling, was responsible for creating the hormonal pathways necessary to sustain amenorrhea. Now, however, it seems that this relationship is one of correlation not causation as prolactin levels in the blood plasma are simply an indicator of suckling frequency. Suckling, and the subsequent release of prolactin, is not directly responsible for postpartum infecundity.
