Daniel: "Re: OB:Cesarean for anencephaly" The reason why progesterone levels are measured in investigating fertility is that the follicle doesn't luteinise until LH (Luteotropic Hormone) surges to produce ovulation. Without the LH surge there is no ovulation and without ovulation there is no progesterone production because the follicle doesn't luteinise. It is possible to have an "unruptured luteinised follicle" (so-called) but these are rare. I have always believed that ovulation is an esssential prerequisite for progesterone production. > From: "Jeffrey W.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
