SLIDE 15
(Nancy Pratt)
Here's a couple of examples of what
we see in an ultrasound of Shanthi. These are both pictures of
her reproductive tract. Here, this image here is in the previous
cycle, the late luteal phase of her cycle. This band right on
the top is the rectal wall, the intestinal wall, and then this
dark band is the vagina, and in the middle is the lumen of the
vagina. The white stripe is mucous inside the vagina. On the
left of the picture, the V-shaped structure is the cervix. Now,
about a month later, we're getting into late September, in the
follicular phase of the cycle, you can see most of the mucous
is gone in the vagina, the vagina is very much more folded, and
the cervix is a much larger structure. So these are the kinds
of changes we're looking for to help us define when ovulation
is going to occur.
