title: Endometrial assessment in a group of infertile women on stimulated cycles for IVF: immunohistochemical findings.
abstract: An immunohistochemical assessment of the endometrium was carried out in a group of IVF patients on stimulated cycles, in order to evaluate this technique against standard histological methods and to consider its application in a clinical situation. Monoclonal antibodies to the two cycle-dependent proteins: pregnancy associated endometrial alpha 2-globulin (alpha 2-PEG) and 24K (a protein originally isolated from an oestrogen-dependent breast tumour line, MCF-7) were used in the experiment. Immunohistochemical results concerning the effect of drug stimulation, age and date of biopsy on the secretory state of the endometrium revealed trends which were consistent with previous histological data, helping to confirm the value of this new technique. In addition, several specimens were found to have a normal, i.e. in phase, histological appearance but to have an atypical pattern of protein secretion. These observations suggest that biochemical monitoring of the uterus should be used in conjunction with routine histological dating.
