Breast cancer is the most prevalent malignancy among women under 50. Improvements in diagnosis and treatment have yielded an important decrease in mortality in the last 20 years. In many cases, chemotherapy and radiotherapy develop side effects on the reproductive function. Therefore, before the anti-cancer treatment impairs fertility, clinicians should offer some techniques for fertility prese...

the use of ovarian stimulation for infertility treatment is associated with side effects of ovarian hyperstimulation syndrome (ohss) and potential cancer risk. this is also true in high risk women such as those polycystic with ovary (pco) and polycystic ovarian syndrome (pcos). in vitro maturation (ivm) of oocytes was primarily developed to make ivf safe for women with pco and at high risk of o...

BACKGROUND GnRH agonist was recently suggested as a novel luteal-phase support that may act at different levels, including the pituitary gonadotrophs, the endometrium and the embryo itself. This prospective randomized study evaluates the effect of GnRH agonist administered in the luteal phase on ICSI outcomes in both GnRH agonist- and GnRH antagonist-treated ovarian stimulation protocols. MET...

Ovarian hyperstimulation syndrome (OHSS) is an important complication of ovarian stimulation and IVF that enhances patients' morbidity. To evaluate any increased incidence of hospitalization from severe OHSS during 2000, this study analysed certain clinical, ultrasound and laboratory characteristics of hospitalized patients with severe OHSS. These studies were carried out on women undergoing IV...

OBJECTIVE To evaluate the correlation between serum levels of anti-Müllerian hormone (AMH) and ovarian response to mild stimulation in normoovulatory women and anovulatory women with polycystic ovary syndrome (PCOS). METHODS Seventy-four cycles of mild stimulation (clomiphene citrate+gonadotropin followed by timed intercourse or intrauterine insemination) performed in normoovulatory women (57...

BACKGROUND The role of exogenous LH supplementation in ovarian stimulation is a matter of debate. Here we evaluate the impact of exogenous LH on oocyte yield and developmental competence in an oocyte donation programme. METHODS Oocyte donors were randomized (computer-generated randomization list) to groups stimulated with FSH alone or with a combination of FSH and LH after pituitary down-regu...

background: evaluation of anti-mullerian hormone (amh) cut-off levels in assisted reproductive technology (art) as predictive factor for individualization of stimulation protocols and to avoid ovarian hyperstimulation syndrome (ohss). materials and methods: in a retrospective study, 177 infertile patients were assessed for amh in serum and follicular fluid (ff) on the day of follicular puncture...

The role of follicle stimulating hormone (FSH) in assisted repro­ ductive technology is well understood, though there is still no published consensus on the need for exogenous luteinizing hormone (LH) in controlled ovarian stimulation. There is a dilemma regarding the usefulness of LH supplementation in controlled ovarian stimulation despite growing understanding of the LH and FSH interrelation...

Recent advances in the technology of vitrification of human oocytes and embryos have increased the opportunities for fertility preservation in cancer patients. Ovarian stimulation in this group of patients is associated with some unique challenges. A controversy in this field rotated around the hypothesis that the transient elevations of estrogen during an IVF cycle may stimulate tumor growth; ...
