Psychosocial stress and the menstrual cycle

Area of Science:

• Reproductive endocrinology
• Psychoneuroendocrinology
• Women's health

Background:

• The menstrual cycle is influenced by various factors, including psychological stress.
• Stress hormones like adrenaline, noradrenaline, and cortisol may impact cycle regularity.
• Understanding these relationships is crucial for female fertility assessment.

Purpose of the Study:

• To investigate the association between mood states, urinary stress hormone levels, and menstrual cycle adequacy.
• To examine if higher stress levels correlate with abnormal menstrual cycles (oligomenorrhoea, unclear cycles).
• To determine the relationship between stress levels and menstrual cycle phase lengths (follicular and luteal).

Main Methods:

• Analysis of 120 non-conception cycles from 34 women.
• Measurement of urinary stress hormones (adrenaline, noradrenaline, cortisol).
• Assessment of mood states and menstrual cycle characteristics (regularity, phase lengths).

Main Results:

• A non-significant trend suggested higher stress in women with irregular or unclear cycles.
• No consistent relationship was found between stress measures and follicular or luteal phase length within individuals.
• No consistent pattern emerged between mood states and stress hormone excretion.

Conclusions:

• The study did not find a clear link between stress, mood, and menstrual cycle characteristics in the studied population.
• Subtle menstrual cycle abnormalities and stress warrant further investigation regarding their impact on female fertility.
• More research is needed to elucidate the complex interplay between psychological stress and reproductive health.
