BACKGROUND The forkhead transcription factor Foxo3 is a master regulator and potent suppressor of primordial follicle activation. Loss of Foxo3 function in the mouse leads to premature ovarian failure (POF) due to global follicle activation. METHODS AND RESULTS Here, we show that the mouse Foxo3 locus is haploinsufficient, and that Foxo3-/+ females undergo early reproductive senescence consis...

BACKGROUND Questions remain as to whether surgical excision of ovarian endometriomas might cause damage to ovarian function. To test the hypothesis that ovarian surgery for endometrioma compromises ovarian function and accelerates ovarian failure. METHODS In a tertiary university Clinic, longitudinal prospective cohort study. Patients who underwent laparoscopy for endometriosis between March ...

Some of the limits of our study were already mentioned in our original paper, but they are clarified in this letter better. Overall, we thus just thank the authors for their precious and constructive comments. Array comparative genomic hybridization for the detection of submicroscopic copy number variations of the X chromosome in women with premature ovarian failure Sir, Evidence suggests that ...

OBJECTIVE To describe a new FOXL2 gene mutation in a woman with sporadic blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) and hypergonadotropic hypogonadism. DESIGN Case report. SETTING University medical center. PATIENT(S) A 28-year-old woman. INTERVENTION(S) Clinical evaluation, hormone assays, gene mutation research. MAIN OUTCOME MEASURE(S) FOXL2 gene mutation. RESULT(...

Adolescent idiopathic premature ovarian failure (POF) is extremely rare. In such conditions, there a defect in the process of folliculogenesis axis leading to hypoestrogenic state and infertility. This disorder significantly impacts woman's prospective health, fertility, motherhood. A case 24-year-old female diagnosed with adolescent under hormone replacement therapy who visited us for fertilit...

BACKGROUND In premature ovarian failure (POF), cessation of menstruation occurs before the expected age of menopause. Approximately 1% of women are affected. FMR1 premutation was reported to be responsible for up to 3.3%-6.7% of sporadic POF and 13% of familial cases in Caucasians, while the data was absent in Chinese population. Therefore, the impact of FMR1 CGG repeat on ovarian reserve is ne...

CONTEXT Ovarian dysfunction is classically categorized on the basis of cycle history, FSH, and estradiol levels. Novel ovarian markers may provide a more direct insight into follicular quantity in hypergonadotropic women. OBJECTIVE The objective of the study was to investigate the distribution of novel ovarian markers in young hypergonadotropic women as compared with normogonadotropic regular...

This meta-analysis was designed to assess the overall performance of GnRHa in preserving the ovarian function in young women undergoing chemotherapy. Electronic literature databases including Pubmed, MEDLINE, Cochrane library, Embase, CNKI and Wanfang were searched for articles published till November, 2013. The articles written in both Chinese and English were considered. Only randomized contr...

We present ovulation that occurred after the administration of traditional Chinese herbal medicine for 3 months in a woman with premature ovarian failure (POF) and secondary amenorrhea for 8 years. Traditional Chinese medicine concentrated herbal extracts of cooked rehmannia, Chinese yam, wolfberry fruit, dogwood fruit, cyathula root, dodder seed, antler glue, tortoise-plastron glue, epimedium ...

Among the causes of premature ovarian failure (POF) two groups of factors are reported: factors which lead to decrease of follicular number and factors which stimulate follicular atresia. In the first group genetic factors are the most important whereas in the second: enzymatic autoimmunological, iatrogenic, toxins and infections are reported. In 1986 familiar POF on the background of long arm ...
