Want to include the menstrual cycle in your scientific work, but aren't sure how to do it? My lab (@katjaschmalen) have just published an article on best practices for observational studies of the cycle! Thread below! 🧵

Despite decades of research on the menstrual cycle, empirical studies have not adopted consistent methods for operationalizing the menstrual cycle, resulting in confusion in the literature and limited possibilities to conduct systematic reviews and meta-analyses.

Below, I summarize this "how to" article, and relay some of the key points!

PARTICIPANTS: All participants should be naturally-cycling people with ovaries (remember that they are not necessarily "women"! 🏳️‍⚧️ ⚧).

We provide a Reproductive Status Questionnaire with rules for identifying naturally-cycling people (current function of the sexual organs and hormonal/other medications that stop the cycle).

#OTD 1901, Queen Victoria's funeral took place. Here's a little medical history THREAD (1/9) about one of Britain's longest reigning monarchs. 👇

"Queen Victorian on her death bed" by Emil Fuchs.

(2/9) On 7 April 1853, Queen Victoria became the first monarch to use chloroform to ease the pains of childbirth. Prince Leopold was born within 53 minutes of administration of the drug, which Victoria described as "delightful beyond measure.”

(3/9) The anaesthetic powers of chloroform was first discovered in 1847 by the Scottish physician James Young Simpson. He and his two friends experimented with it on the evening of November 4th. At first, they felt very cheerful and talkative. After a short time, they passed out.

(4/9) Impressed with the drug’s potency, Simpson began using chloroform as an anaesthetic. In December 1847, he delivered the first baby using it. Simpson nicknamed the girl “Saint Anaesthesia.” Her real name was Wilhelmina Carstairs, pictured here.

(5/9) During this time, Queen Victorian was pregnant with her sixth child. She heard of Simpson’s discovery and was keen to benefit from it, but royal doctors cautioned against it, claiming that painful contractions during labour were ordained by God.
