Background/aim: Ovarian transplantation can preserve fertility in cancer patients. The aim of this study was to compare ovarian transplantation into granulation tissue (GT) versus back muscle (BM) sites and also to investigate the effects of N-acetylcysteine (NAC) as an antioxidant on ovarian survival in a rat autograft model.Materials and methods: Twenty-eight adult female rats were divided in...
Ovariectomy and ovarian tissue cryopreservation has the potential to preserve the natural fertility of cancer patients prior to sterilizing chemo- and radiotherapies. Ovarian tissue cryopreservation with the conventional slow-freezing method has yielded limited success, partly because of oocyte loss during freeze-thaw and subsequent transplant. Based on the high-efficiency vitrification Cryotop...
BACKGROUND The stripping technique for endometriomas excision has been reported to be associated with follicular loss. The objective of this trial was to evaluate the presence and nature of ovarian tissue adjacent to the endometrioma cyst wall obtained by stripping with different techniques. METHODS Forty-eight patients with ovarian endometrioma were enrolled in two consecutive independent ra...
Ovarian Remnant syndrome (ORS) is the presence of residual ovarian tissue after an oophorectomy was performed whether associated with a hysterectomy or not. We report case 39-year-old woman past surgical history total abdominal and left salpingo-oophorectomy indication placenta accreta incidentally discovered during caesarian section. The patient presented pelvic pain diagnosed ORS. She success...
INTRODUCTION The aim of this study is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries. MATERIAL AND METHODS A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard pro...
OBJECTIVE To evaluate ovarian tissue inadvertently excised with benign cysts during laparotomy or laparoscopy. DESIGN Prospective study. SETTING Private and university hospitals. PATIENT(S) 260 women, 20 to 35 years old, with unilateral benign ovarian cysts. INTERVENTION(S) One hundred fifty women operated by laparoscopic cystectomy stripping technique, and 110 women operated by laparot...
Ovarian tissue banking is a developing technique aimed to preserve fertility in women at risk for premature ovarian failure (1–3). It entails cryopreservation of ovarian tissue with the option of autografting. Reports on the autografting of cryopreserved ovarian cortex segments describe the resumption of steroid production (4), follicle development (5, 6), and (in sheep) model successful pregna...
OBJECTIVE To investigate the effect of the dimethyl sulfoxide (DMSO) and EFS-40 during vitrification on the expression of angiogenic factors in vitrified mouse ovarian tissue. METHODS The ovarian tissues were obtained from 5 or 6 weeks aged ICR mouse. Ovarian tissues were divided into four groups: ovarian tissue without cryopreservation (control, group I), ovarian tissue vitrified with 15% DM...
