Patient's question:
How to check luteal function?Doctor's answer:
Hello, the examination of luteal function is usually performed after ovulation, with serum luteal function tests. It can be confirmed by measuring basal body temperature and examining the endometrium. If the luteal phase temperature is shorter than 12 days, or the temperature rise is slow, the decline is early, or there is significant fluctuation in luteal phase temperature, these are all signs of luteal phase deficiency. However, note that it is necessary to measure the basal body temperature for three menstrual cycles continuously to confirm.For the use of progesterone supplementation therapy to treat infertility, it is generally recommended to start medication 2-3 days after ovulation. Even for habitual early miscarriage, medication should be started 2-3 days after ovulation, just like in infertility treatment. As for the duration of medication, some scholars suggest stopping it on the 14th day after ovulation to prevent pseudopregnancy. Others advocate continuing medication until menstruation occurs. If menstruation does not occur after delay, a pregnancy test can be performed. If pregnancy is confirmed, medication should be continued until the 12th week of pregnancy.
Regarding the use of synthetic progestins, whether by injection or oral administration, they cannot replace progesterone.
