Increasing 125I-human chorionic gonadotrophin specific binding in human granulosa cells by follicle-stimulating hormone and follicular fluid.

It has been reported that success at in-vitro fertilization/embryo transfer (IVF/ET) treatment is increased by follicular fluid (FF) re-injected into the abdomen. In the present study a possible direct effect of FF on human granulosa cell (GC) progesterone (P4) secretion and LH/human chorionic gonadotrophin (HCG) receptor content was studied in the presence and absence of FSH. Human GC cultured for 8 days in medium alone showed a 40-fold decrease in P4 secretion.

IgG and IgA content of vaginal fluid during the menstrual cycle.

Immunoglobulin levels in cervicovaginal secretions during the menstrual cycle have not been well characterized biochemically. We determined the IgG and IgA concentrations in vaginal fluid obtained by patient self-sampling with an Ovu-Trac aspirator. Vaginal fluid IgG levels were less than 1-270 mg/dL.
