Failure to improve a thin endometrium in the late proliferative phase with uterine infusion of granulocyte-colony stimulating factor
Abstract
PURPOSE: To determine if the treatment with uterine infusion of granulocyte colony-stimulating factor (G-CSF) can improve endometrial thickness in an infertile woman with a double uterus, who consistently showed a thin endometrium in the late proliferative phase either in controlled ovarian hyperstimulation (COH) IVF-ET cycles or with graduated estrogen/sildenafil protocols for frozen embryo transfer (ET).
MATERIALS AND METHODS: A single uterine infusion of G-CSF was performed in the late proliferative phase in a woman who only attained a five-mm thickness despite a high dose vaginal and oral estradiol regimen plus sildenafil.
RESULTS: No increase was found within a couple days.
CONCLUSIONS: A previous four-case study in another center found 100% improvement in the endometrial thickness in women with consistently thin endometria. Perhaps the uterine anomaly in the present case prevented the response of the endometrium.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
