Sir, Ovarian hyperstimulation syndrome is most commonly an iatrogenic complication of exogenous gonadotropin administration for ovulation induction. Its clinical presentation varies from abdominal pain and bloating, nausea, vomiting, and ovarian enlargement to possibly life‐threatening conditions including renal failure, hypovolemic shock, adult respiratory distress syndrome, thromboembolism, a...
Background and purpose: Although adjunct chemotherapy may increase life in non-menopausal breast cancer patients، however، it may cause short-term complications such as nausea، vomiting، alopecia، as well as long-term complications in ovarian failure and premature menopausal. The objective of this study was to investigate chemotherapy-induced secondary amenorrhea in non-menopausal women with br...
We present 2 cases of likely rare event. In case 1, 3rd degree consanguineous marriage revealed inv(6) with same break points in parents who were found to be phenotypically normal. The same inv(6) being inherited in progeny but presented with low AMH (anti Mullerian hormone) and high level of FSH (follicular stimulating hormone) leading to polycystic ovarian syndrome/premature ovarian failure. ...
Type 2 diabetes causes structural and functional changes in the myocardium, which is called cardiomyopathy. Diabetic cardiomyopathy (DCM) is a distinct primary disorder process, independent of coronary artery disease, which leads to heart failure in diabetic patients. Also, DCM is a multifaceted disorder that is one of the leading causes of death in elderly and postmenopausal women. Menopause i...
BACKGROUND Some reports show that it is possible to isolate immature oocytes from human ovarian tissue retrieved by a cortex biopsy or ovariectomy of non-stimulated ovaries and mature them in vitro. The mature oocytes can be vitrified and stored for in vitro fertilization, which, along with ovarian tissue cryopreservation, is mostly practiced in young cancer patients to preserve their fertility...
BACKGROUND Oocyte retrieval failure following an ovarian hyperstimulation protocol is uncommon in assisted reproductive technology (ART) programs. We analyzed the predictive factors for oocyte retrieval failure following controlled ovarian hyperstimulation (COH) with gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols in ART programs. METHODS This study was a retrospec...
Over the past decades, prognosis of advanced stage epithelial ovarian cancer remains very poor, despite the development of new chemotherapeutic drugs, as well as molecular targeted agents. Late presentation and frequent chemoresistance account for the poor prognosis. Emerging studies have shown that many genetic changes, especially p53 mutation, are associated with the chemoresistance. However,...
Background. Fertility preservation is applied to patients with cancer who may be rendered sterile from chemotherapy or radiotherapy. Fluorouracil is considered as having almost no effect on human reproductive function, although clinical data defining infertility risk is negligible. Case. Controlled ovarian stimulation, in vitro fertilization (IVF), and embryo freezing were performed before fluo...
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...
Premature ovarian failure is a major cause of female infertility. The genetic causes of this disorder remain unknown in most patients. Using whole-exome sequence analysis of a large consanguineous family with inherited premature ovarian failure, we identified a homozygous 1-bp deletion inducing a frameshift mutation in STAG3 on chromosome 7. STAG3 encodes a meiosis-specific subunit of the cohes...
