Diminished fertility and poor ovarian response pose a conundrum to the experts in the field of reproductive medicine. There is limited knowledge about the risk factors of diminished ovarian reserve other than the iatrogenic ones. One of the leading causes of infertility in women today is diminished ovarian reserve (DOR). DOR is characterized by a low number of eggs in a woman's ovaries and/or w...

The standard goal of all fertility treatments is the improvement of pregnancy rates in infertile patients. Within the last 20 years, ovulation induction has contributed to the success of assisted reproduction techniques e.g. in vitro fertilization (IVF) and embryo-transfer (ET). The efficacy of these techniques depends on a personalized protocol of controlled ovarian hyperstimulation (COH) and ...

Ovarian reserve reflects both the quantity and quality of oocytes available for procreation, and is affected by many known and unknown factors. ABO blood type is related to a number of infertility processes, but it is unclear whether and how ABO blood type affects ovarian reserve. Here, we explored the relationship between ABO blood type and ovarian reserve in Chinese women with subfertility. D...

diminished ovarian reserve (dor) significantly decreases the success rate of the assisted reproductive technique (art). in this study, we assessed the effect of melatonin on the art outcomes in women with dor. a double-blinded, randomized, clinical trial was performed on 80 women with dor as a pilot study in shiraz, between 2014 and 2015. dor was defined as the presence of 2 of the following 3 ...

BACKGROUND With infertility populations in the developed world rapidly aging, treatment of diminished ovarian reserve (DOR) assumes increasing clinical importance. Dehydroepiandrosterone (DHEA) has been reported to improve pregnancy chances with DOR, and is now utilized by approximately one third of all IVF centers world-wide. Increasing DHEA utilization and publication of a first prospectively...

OBJECTIVES Ovarian reserve is defined as the capacity of the ovary to provide fertile oocytes. Diminished ovarian reserve (DOR) is a disorder in which ovaries are prone to go through early menopause. Where this loss of function occurs before the age of 40, it results in the premature ovarian failure (POF) disease. Throughout folliculogenesis, the follicle-stimulating hormone receptor (FSHR) sta...

OBJECTIVE To compare the in vitro fertilization (IVF) outcomes between women with diminished ovarian reserve (DOR) after endometrioma operation and women with DOR without ovarian surgery. METHODS This retrospective case-control study included 124 women aged under 40 and had DOR (serum anti-Müllerian hormone level <1.1 ng/mL or antral follicle count ≤6). They participated in fresh first and/or...

BACKGROUND Diminished ovarian reserve (DOR) is one of the causes of infertility in young women. In this prospective study, gene expression profiling (GEP) of corona radiata cells (CRC) was performed to identify genes deregulated in DOR patients. METHODS Microarray-based GEP of CRC isolated from eight women undergoing IVF was performed to identify genes differentially expressed between patient...

Background: Diminished ovarian reserve (DOR) is a primary infertility disorder characterized by a reduction in the number and/or quality of oocytes, usually accompanied by high follicle-stimulating hormone (FSH) levels and regular menses. DOR aetiology factors are different, such as genetic factors, ageing, autoimmune disorders, adrenal gland impairment factors and iatrogenic causes, e.g. chemo...
