Q. I heard that triphasic COCs can cause mood changes more than other types. Is it true? Why?
Answer: Here's what I could find:
taken from: J. Bancroft, D. Sanders, P. Warner and N. Loudon, The effects of oral contraceptives on mood and sexuality: a comparison of triphasic and combined preparations. J Psychosom Obstet Gynaecol, 7 (1997), pp. 1–8.
"OCs may also aggravate the “vulnerability factor”; in a comparison of triphasic and monophasic OCs, women with a tendency to premenstrual mood change showed more negative mood on the triphasic pill, usually occurring during mid cycle."
The why part is harder to answer. Any ideas?
