The prevalence of menopausal symptoms in southern Chinese women is low, and this is accompanied by low usage of hormone replacement therapy.

We aimed to evaluate the effectiveness of granulocyte colony-stimulating factor (G-CSF) administration for infertile women with thin endometrium in frozen embryo transfer program. Among 59 infertile patients with thin endometrium (≤7 mm), 34 patients received uterine infusion of recombinant human G-CSF (100 μg/0.6 mL) on the day of ovulation or administration of progesterone or human chorionic gonadotropin, with 40 cycles defined as G-CSF group and 49 previous cycles as self-controlled group, and 25 patients refused, with 80 cycles defined as the control group. Higher proportion of induced cycles and lower proportion of natural cycles were observed in the G-CSF group, when compared to the self-controlled group or control group (P < .05). The cycle cancellation rate was, in descending order, 69.39% in self-controlled group, 48.75% in control group, and 17.50% in G-CSF group, with significant difference (P < .05). The implantation rate and clinical pregnancy rate per embryo transfer were similar in all the groups (P > .05). Our study fails to demonstrate that G-CSF has the potential to improve embryo implantation and clinical pregnancy rate of the infertile women with thin endometrium.

BackgroundResistant ovary syndrome (ROS) is a rare endocrine disorder characterized with hypergonadotrophic hypogonadism. Infertility is a common complaint of woman presenting with ROS, and little progress has been made in term of reproduction with the patient’s own gamete. So far only one case report of live birth has been reported after in vitro maturation (IVM) of oocytes in a patient suffering from ROS in 2013.Case presentationA secondary infertile woman of 33 years-old was manifested with oligomenorrhea and markedly increased gonadotropin levels around postmenopausal range, but had normal antral follicle count, normal serum inhibin B and anti-Müllerian hormone levels. She had normal karyotype of 46,XX and normal thyroid function. There were no abnormal findings in some autoantibody assays and FSH receptor sequencing. After oral contraceptive pills combined with triptorelin depot were administered, her gonadotropin levels reduced but it showed no response to high doses of exogenous gonadotropins (hp-HMG 300IU/d for 15 days). Then endometrium was prepared with estradiol valerate and IVM from small antral follicles were performed. Five immature oocytes were retrieved. Twenty-four hours after IVM culture, 3 oocytes matured to metaphase II stage and were inseminated by intracytoplasmic sperm injection using her husband’s sperm. Two top-quality embryos were transferred and one embryo was cryopreserved. The patient got pregnant and delivered a healthy boy at term.ConclusionIVM using their own oocytes could be an available treatment for infertile women with ROS.
