In the modern environment one is exposed to various stressful conditions. Stress can lead to changes in the serum level of many hormones including glucocorticoids, catecholamines, growth hormone and prolactin. Some of these changes are necessary for the fight or flight response to protect oneself. Some of these stressful responses can lead to endocrine disorders like Graves' disease, gonadal dysfunction, psychosexual dwarfism and obesity. Stress can also alter the clinical status of many preexisting endocrine disorders such as precipitation of adrenal crisis and thyroid storm.

An organism's reproductive fitness is sensitive to the environment, integrating cues of resource availability, ecological factors, and hazards within its habitat. Events that challenge the environment of an organism activate the central stress response system, which is primarily mediated by the hypothalamic-pituitary-adrenal (HPA) axis. The regulatory functions of the HPA axis govern the cardiovascular and metabolic system, immune functions, behavior, and reproduction. Activation of the HPA axis by various stressors primarily inhibits reproductive function and is able to alter fetal development, imparting a biological record of stress experienced in utero. Clinical studies and experimental data indicate that stress signaling can mediate these effects through direct actions in the brain, gonads, and embryonic tissues. This review focuses on the mechanisms by which stress activation of the HPA axis impacts fertility and fetal development.

Physiological and psychological stress disrupts hypothalamic GnRH pulsatility via CRH-cortisol pathways, producing downstream impairments in LH and FSH secretion that manifest as anovulation, delayed ovulation, follicular phase prolongation, or luteal phase deficiency -- all of which are documented cycle-by-cycle on the CrMS chart. NaProTECHNOLOGY addresses stress-induced HPO axis dysfunction by identifying the specific cycle-level disorder through charting and targeted hormone profiling, then applying cycle-appropriate ovulation induction and cooperative hormone support alongside correction of the underlying physical or psychological stressor.

Studies with animals of both sexes show that the adrenal glands release progesterone in addition to cortisol in response to stress. However, little is known about the progesterone response to stress in naturally cycling women. We investigated the effect of stress on estradiol, progesterone, and cortisol levels in women during the follicular phase of the menstrual cycle. We found that physical stress (the cold pressor test) had no effect on estradiol levels, but increased progesterone and cortisol. We also found positive correlations between baseline progesterone and cortisol levels, as well as between the change in progesterone and cortisol before and after water exposure in both the stress and control sessions. Mediation analyses revealed during the stress session, the change in progesterone from baseline to 42-min post-stress onset was mediated by the magnitude of change in cortisol levels across the same time span. Overall, these findings reveal that progesterone released in response to stress as observed in animals and men extends to women during the low ovarian output follicular phase of the menstrual cycle, and that the mechanism of release may be similar to the mechanism of cortisol release.
Postpartum mood disorders are common. The clustering of mood-disorder episodes after birth compels a search for factors particularly potent during childbearing. In this article, the complex relationships between the dynamic postbirth physiological environment and mood disorder are discussed. Available studies show a lack of evidence that serum levels of gonadal hormones account for mood disturbance in women. However, substantial amounts of data demonstrate their ability to modulate other neuroendocrine systems. Alterations in hypothalamic-pituitary-adrenal (HPA) axis function attributable to childbearing show remarkable similarity to those observed in depressed women. Postpartum women are also at increased risk for hypothalamic-pituitary-thyroidal (HPT) axis dysfunction that may increase affective-disorder vulnerability. A decreased rate
