Estrogen Replacement

Hi I'm Dr. Jared Nielsen. I'd like to talk to you about hormone replacement therapy for females and particularly, the utilization of progesterone. A lot of books have been written. A lot of studies have been promoted about the use of progesterone for the post‑menopausal female.
The interesting thing though, when we think about progesterone utilization, is the natural function of progesterone, and a correlation to thyroid hormones be in the body. Let me say it this way. When a young woman, a young expecting, or potentially pre‑expecting mother is trying to regulate her cycle, and observe when it is that she ovulates, she'll often use her temperature as that indicator.
The temperature spike in the female body is associated with progesterone elevations that cause then, an activation of a thyroid peroxidase enzyme, which actually binds tyrosine to iodine to form thyroid hormone, or T4.
What's important of this to know is that the progesterone in in the mid‑cycle actually then stimulates this TPO, which then allows an increase in the T4, which is measured in the body as an increase in body, or basal metabolic temperature. Your body temperature will actually increase due to this increased production of thyroid hormone during an ovulation cycle.
The interesting thing about this correlation to note then is, if a female actually has an antibody that attacks her thyroid peroxidase, then she actually experiences something that's actually suppressing this normal, productive activity...
