چکیده

OBJECTIVE To describe isolation and in vitro maturation of primary oocytes from the ovarian cortex in the presence of hypothalamic pituitary down-regulation. DESIGN Case report. SETTING Tertiary care university-affiliated hospital. PATIENT(S) An 18-year-old patient was given treatment with the ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine) protocol for Hodgkin's disease. She underwent ovarian tissue cryopreservation while being cotreated with GnRH agonist because of disease relapse. INTERVENTION(S) Laparoscopic oophorectomy, ovarian tissue cryopreservation, and in vitro maturation of primary oocytes. MAIN OUTCOME MEASURE(S) Maturation of primary oocytes isolated from the medium used for preparation of ovarian tissue. RESULT(S) Twenty-one immature germinal vesicle-stage oocytes were isolated from the medium of dissection. All were incubated in in vitro maturation medium, and five were maturated and frozen. CONCLUSION(S) The fact that germinal vesicle-stage oocytes were present in our patient's medium despite hormonal down-regulation demonstrates that GnRH agonist does not completely inhibit antral follicle development.

Resurgence of Minimal Stimulation In Vitro Fertilization with A Protocol Consisting of Gonadotropin Releasing Hormone-Agonist Trigger and Vitrified-Thawed Embryo Transfer

Minimal stimulation in vitro fertilization (mini-IVF) consists of a gentle controlled ovarian stimulation that aims to produce a maximum of five to six oocytes. There is a misbelief that mini-IVF severely compromises pregnancy and live birth rates. An appraisal of the literature pertaining to studies on mini-IVF protocols was performed. The advantages of minimal stimulation protocols are report...

High yield of oocytes without an increase in circulating estradiol levels in breast cancer patients treated with follicle-stimulating hormone and aromatase inhibitor in standard gonadotropin-releasing hormone analogue protocols.

BACKGROUND Adjuvant/neoadjuvant chemotherapy in breast cancer patients may be associated with amenorrhea and a marked reduction in ovarian reserve. OBJECTIVES To assess the use of letrozole with follicle-stimulating hormone (FSH) in gonadotropin-releasing hormone (GnRH) analogue protocols, based on reported attempts to avoid the estradiol (E2) increase during controlled ovarian hyperstimulati...
