complex issue
Fertility in TCM is a really complex issue and infertility can stem from a wide variety of causes and disharmonies. Therefore, treatment varies widely from case to case.
A general practice for regulating menstruation and ovulation would be, according to days in the menstrual cycle:
26-4: Invigorate Blood
5-11: nourish Kidneys, Blood, and Yin
12-25: Harmonize Liver
Some people say from day 18-25, nourish Kidney Yang.
This is rough, and will have to vary according to each woman's individual constitution and menstrual history.
