Premature ovulation or premature luteinization
was not seen in any woman (Table 3).
By circa 1980 Dr Scully had collected a series of 13 cases in which a tubular pattern in a Krukenberg tumor, often associated with stromal luteinization
(responsible in some cases for androgenic manifestations), resulted in the misdiagnosis of a SLCT.

Activation of LHR in follicular cells by the LH surge causes ovulation and luteinization
. This process alters their responsiveness to external signals allowing luteal cells to respond to a new set of hormones, the most important being PRL and LH .

Then hyperplastic theca cells of these small follicles show luteinization
stimulated by high LH levels .
Does premature luteinization
or early surge of LH impair cycle outcome?
Although sFRP-4 expression is associated with luteinization
events in rodent ovaries (20), its role in the terminal differentiation (i.e., luteinization
) of GCs and the underlying molecular mechanism remains largely unknown.

of mouse ovaries.
The most common treatment for cystic ovaries is GnRH, which results in an immediate increase in LH secretion and luteinization
In cow and pig CL  leptin and its receptor expression increase in association with luteinization
and decline alongside the luteal regression.
