[Semiquantitative measurement of progesterone receptors in luteal-phase-defect endometrial cells during secretory phase].
To investigate the changes of endometrial progesterone receptor (PR) of luteal-phase-defect (LPD) patients during the secretory phase, thirteen patients with complaints of infertility or habitual abortion were studied. During the early-mid secretory phase, endometrial tissue was obtained by dilatation and curettage (D & C) for histological and receptor study: meanwhile serum E2, P, FSH, LH and PRL were measured. Based on histologic diagnosis, the patients were divided into two groups: the LPD group (n = 7) and the normal control group(n = 6). PR content was determined by immunohisto-chemical (IHC) assay. The results showed that during the early-mid luteal phase a significantly low PR content on endometrial glandular nucleus was observed in LPD group, compared with normal control(6.75 +/- 2.57 vs 9.50 +/- 1.64 P < 0.05), but no difference in serum progesterone was noted between the two groups. These findings suggest that during early-mid secretory phase, PR content on endometrial glandular nucleus decreases in LPD cases, which results in deficient response of endometrium to proper stimulus of progesterone. This change may cause endometrial secretory deficiency and blockade of embreyo implantation. That is why infertility or habitual abortion happened.
