Armstrong Striations BBT: Essential Aspects

Armstrong striations, also known as "ring shadows" or "chorionic ring," are unique patterns observed in the basal body temperature (BBT) charts of some women. They appear as distinct dips or depressions in the temperature curve that align with the menstrual cycle.

Armstrong striations were first described by Dr. Thomas Armstrong in 1974. While their exact cause is still not fully understood, they are believed to be associated with hormonal changes during the menstrual cycle. Estrogen is thought to be responsible for the rise in temperature, while progesterone causes the temperature to fall.

Analyzing Armstrong striations can provide valuable insights into a woman's reproductive health. Their presence and depth can indicate the timing of ovulation, luteal phase defects, and other potential hormonal imbalances.

To interpret Armstrong striations in a BBT chart, it's essential to:

Look for distinct dips aligning with specific days of the menstrual cycle.
Note the duration and depth of the dips.
Consider the timing of ovulation (typically 14 days before the start of the next period) and the luteal phase length (normally 10-14 days).

By carefully analyzing Armstrong striations, women can better understand their fertility patterns and identify any potential issues that may require further medical investigation.
