The success of human oocyte cryopreservation depends on morphological and biophysical factors that could influence oocyte survival after thawing. Various attempts to cryopreserve human oocytes have been performed with contrasting results. Therefore the effect of some factors, such as the presence or absence of the cumulus oophorus, the sucrose concentration(More)
OBJECTIVE To describe the first birth achieved after intracytoplasmic sperm injection (ICSI) of cryopreserved human oocytes. DESIGN Case report. SETTING University of Bologna Hospital, Department of Obstetrics and Gynecology, Reproductive Endocrinology Unit, IVF and Infertility Center. PATIENT(S) One patient undergoing IVF. INTERVENTION(S)(More)
We studied a group of obese hyperandrogenic amenorrheic women to determine the effects of weight loss on anthropometry, hormonal status, menstrual cycles, ovulation, and fertility. Fourteen women had polycystic ovaries, two the hyperandrogenism-insulin resistance-acanthosis nigricans syndrome, one hirsutism of adrenal origin, and three idiopathic chronic(More)
OBJECTIVE A combination of chemotherapy and radiotherapy in young females with cancer has greatly enhanced the life expectancy of these patients, even if these treatments have a highly deleterious effect on the ovary and cause a severe depletion of the follicular store. Cryopreservation of ovarian tissue before chemotherapy and/or radiotherapy, followed by(More)
Ninety-five adolescents with menstrual irregularities persisting since menarche were studied and the data analyzed in relation to gynecologic age. In each year, in the premenstrual phase, luteinizing hormone (LH), testosterone (T), and androstenedione (delta 4A) values were higher than those of adults. Estrone (E1), estradiol (E2), 17-hydroxyprogesterone(More)
To investigate the relationship between body fat distribution, sex hormones, and hyperinsulinemia in male obesity, we examined 52 obese men (body mass index [BMI], 35.0 +/- 6.1, mean +/- SD) and 20 normal-weight controls. Their waist to hip circumference ratio (WHR), which was used as an index of fat distribution, was 0.985 +/- 0.052 and 0.913 +/- 0.061 (P(More)
Oocyte cryopreservation is a viable solution for the ethical problems related to embryo storage, and the only available technique for preservation of fertility in women who have to undergo chemo- or radiotherapy. The main problems with oocyte cryopreservation are concerned with the survival rate and the fertilization rate. Recently the introduction of the(More)
Chemotherapy and/or radiotherapy protocols have improved the long-term survival of cancer patients. Frequent consequences of antiblastic treatments, used to eradicate malignancies, are the partial loss of ovarian function, which in children and young women can result in permanent sterility. Ovarian tissue cryopreservation implemented before the beginning of(More)
It has been demonstrated previously that freezing oocytes within 2 h of retrieval increases the efficiency of cryopreservation via a slow-freezing/rapid-thawing protocol with 0.3 mol/l sucrose (SF/RT 0.3). The aim of this multicentre survey was to verify this observation on a larger scale. This was a retrospective study on the clinical outcome of 510 SF/RT(More)
Oocyte cryopreservation has the potential to be an important adjunct to assisted reproductive technologies and bypasses some ethical, moral, and religious dilemmas posed by human embryo cryopreservation. The success of human oocyte cryopreservation depends on morphological and biophysical factors that could influence oocyte survival after thawing. Among the(More)
