OBJECTIVE To determine the effect of storage duration on cryopreserved ovarian tissue using fresh and frozen-thawed samples. METHODS Seventeen fertile patients underwent an ovarian biopsy during elective laparoscopic tubal ligation. The tissue sample was divided into three parts: one part was processed fresh (FG), and two were slowly frozen, cryopreserved for 30 (G30) or 180 days (G180), thaw...

background and aims: ovarian cancer is one of most common causes of cancer related women's mortalities. human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. a few studies also identified hpv dna in ovarian carcinoma tissues. however, some studies did not detect hpv dna in ovarian carcinoma tissues. in this article, we inv...

Comparisons of numbers of antral ovarian follicles and corpora lutea (CL), of blood hormone concentrations, and of follicular fluid steroid concentrations and IGFBP activity were conducted between cows selected (twinner) and unselected (control) for twin births to elucidate genetic differences in the regulation of ovarian follicular development. Ovarian follicular development was synchronized a...

The gradual increase in follicle stimulating hormone (FSH) concentrations in women approaching menopause results from the depletion of the ovarian follicular pool, a process referred to as 'ovarian ageing'. This study investigates whether variable endogenous FSH concentrations, as have been observed in normo-ovulatory young women, are related to menstrual cycle characteristics, including predic...

Background: Follicular pool is reduced after transplantation of vitrified ovary. Therefore, methods should be improved to accelerate ovarian function revival and maintain follicular reserve. In this study hyaluronic acid hydrogel as a scaffold was used to improve restoration of ovarian oestrous cycle. Materials and Methods: 79 mature (~8 weeks) rats having normal estrous cycles were divided int...

Foetal ovarian cysts are the most frequently encountered intra-abdominal cystic masses diagnosed prenatally. The aetiology of foetal ovarian cysts is still unknown, but hormonal stimulation is generally considered to be responsible for the disease. The diagnosis is made by the exclusion of other cystic lesions confined to the foetal abdomen. In this article we report antenatally-detected foetal...

Ovarian tissue freezing or cryopreservation might be the only acceptable method for preserving the young women fertility, before radiotherapy or chemotherapy. This technology might be used for patients with recurrent ovarian cysts or endometriosis, without ovarian stimulation. Many efforts have made to improve cryopreservation conditions that should be seriously considered for cancer patients. ...

Embryoanatomical peculiarities are responsible for low occurrence of inguinal hernias in females. Amongst them, ovarian hernias are rarer. They are commonly noticed in children. An attending surgeon commonly faces diagnostic and operative dilemmas in managing these overtly "simple-looking" clinical scenarios. Although ovarian cysts are one of the common contents of the sac, we report a case of ...

Estrogen appears to enhance cerebral blood flow (CBF). An association between CBF and physiologically altered hormonal levels due to menstrual cycle, menopause, or exogenous manipulations such as ovariectomy or hormone replacement therapy has been demonstrated. The purpose of this study was to determine the association between ovarian stimulation and CBF in vivo by measuring blood flow in the i...

Background: Endometriosis is defined as the presence of endometrial glands and stroma outside the endometrial cavity and uterine musculature. The most common site of endometriosis is pelvis, but endometrotic implants may occur nearly anywhere in the body. Endometriosis is a common and serious gynecologic problem in reproductive age women, who have pelvic pain, dyspareunia, or infertility. The g...
