• Fertility assessment: Difficulty conceiving or evaluating cycle-related hormone patterns.
• Cycle variability: Irregular menstrual cycles or uncertainty around cycle length.
• Ovulatory timing: Difficulty identifying ovulation timing or luteal phase consistency.
• Hormonal symptoms: PMS, mid-cycle spotting or cycle-related migraines.
• Gynaecological history: Partial hysterectomy with ovaries intact or endometrial ablation.
• Intrauterine devices: Use of a Mirena IUD with ongoing hormonal symptoms despite absent bleeding.
• Polycystic ovary syndrome: PCOS with variable or unpredictable cycles.
• Testing timing challenges: Uncertainty about when to test due to long or short cycles.
• Post-contraceptive transition: Hormonal changes following cessation of hormonal birth control.

DUTCH Cycle Mapping™ measures oestrogen and progesterone patterns across multiple points of the menstrual cycle using dried urine samples. Hormone values are reported as metabolites and normalised to creatinine, providing a time-based view that correlates with 24-hour urine collections without requiring full-day sampling.

This approach may be clinically useful when a single-day hormone measurement does not adequately reflect cycle dynamics. Mapping oestrogen and progesterone fluctuations across the cycle allows practitioners to observe timing patterns, relative rises and falls, and consistency between phases that may relate to cycle regularity or hormone-related symptoms.

Practitioners typically use cycle mapping results alongside menstrual history, symptom tracking, lifestyle factors and other laboratory findings. Attention is given to cycle length, ovulation timing, recent contraceptive use and individual context when reviewing patterns with clients.
