Background Premature ovarian failure (POF) is a disorder of multi causal etiology. Autoimmunity has been proposed as a mechanism for some cases of ovarian follicle dysfunction which is evident in POF. The aim of this study was to identify the level of auto-antibodies in POF and familial POF patients. MaterialsAndMethods In this study, auto-antibodies including anti-ovarian antibody (AOA), anti ...

Monozygotic 24-year-old twins presented with discordant ovarian function. One had had premature ovarian failure at the age of 14 years, whereas her sister had normal ovaries and three naturally conceived children. After unsuccessful egg-donation therapy, the sterile twin received a transplant of ovarian cortical tissue from her sister by means of a minilaparotomy. Within three months after tran...

Gynaecography-the radiological visualization of the internal female genitalia after pneumoperitoneum-is a safe and simple procedure. When taken in conjunction with the clinical and laboratory findings the results of gynaecography are often a sufficient basis for diagnosis and a plan of management in women presenting with menstrual irregularity or infertility.

Pluripotency associated transcription factor, SAL-Like 4 (SALL4), might play an important role in conferring totipotency on oocytes. In the present study, we screened SALL4 coding regions for mutations in 100 Han Chinese women with non-syndromic ovarian failure and discovered two novel non-synonymous variants in the SALL4 gene: c.541G>A (p.Val181Met) and c.2449A>G. (p.Thr817Ala). The former var...

Foxo transcription factors have been implicated in diverse biological processes, including metabolism, cellular stress responses, and aging. Here, we show that Foxo3a-/- female mice exhibit a distinctive ovarian phenotype of global follicular activation leading to oocyte death, early depletion of functional ovarian follicles, and secondary infertility. Foxo3a thus functions at the earliest stag...

Background The aim of this study was to assess the ssociation between human transforming growth factor b receptor,type III (TGFBR3) and idiopathic premature ovarian failure (POF) in a Chinese population. MaterialsAndMethods A total of 112 Chinese women with idiopathic POF and 110 normal controls were examined. DNA samples prepared from blood leukocytes were used as templates for polymerase-chai...

background: premature ovarian failure (pof) is a disorder of multi causal etiology. autoimmunity has been proposed as a mechanism for some cases of ovarian follicle dysfunction which is evident in pof. the aim of this study was to identify the level of auto-antibodies in pof and familial pof patients. materials and methods: in this study, auto-antibodies including anti-ovarian antibody (aoa), a...

The mammalian zona pellucida is an extracellular matrix that occurs in growing oocytes, ovulated eggs and pre-implantation embryos, and is known to be involved in several important events during ovarian folliculogenesis and fertilization. Since the zona pellucida is formed at an early stage of oocyte growth, circulating antibodies against zona pellucida may impair ovarian function. In this arti...

Causes of primary ovarian failure are reviewed, focusing specifically on cancer treatment-related modalities. Strategies and future directions for protection of the ovaries during cancer therapy, including ovarian transposition, and conformal radiation techniques are presented.
