OBJECTIVE To compare cost-effectiveness between pituitary down-regulation with a GnRH agonist (GnRHa) short regimen on alternate days and GnRH antagonist (GnRHant) multidose protocol on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcome. DESIGN Prospective, randomized. SETTING A private center. PATIENT(S) Patients were randomized into GnRHa (n = 48) and GnRHant (...

We studied 98 in-vitro fertilization (IVF) patients with a high basal follicle stimulating hormone (FSH; >6.5 IU/l) concentration on day 3 who were treated with a low dose gonadotrophin-releasing hormone agonist (GnRHa) protocol and who had received in the previous 6 months a long protocol with GnRHa in a depot formula. The evaluation was made using the previous IVF cycle of the same patient as...

Objective To evaluate the effects of different ovarian stimulation protocols on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes infertile women with adenomyosis. Methods We carried out a retrospective cohort study among adenomyosis receiving IVF/ICSI treatment, including 257 fresh embryo transfer (ET) cycles and 305 frozen (FET) cycles. In ET cycles, ultra-long, long...

OBJECTIVE To determine if the GnRH antagonist protocol is effective in preventing ovarian hyperstimulation syndrome (OHSS) in potentially high responders. METHODS A total of 660 IVF-ET/ICSI cycles were retrospectively identified. The inclusion criterion was age ≤ 30 years. Cycles were divided into two groups: a GnRHa group and a GnRHant group. In the GnRHa group, the patients received one sin...

Gonadotropin-releasing hormone analogs (GnRHa) are widely used to treat central precocious puberty (CPP). The efficacy and safety of GnRHa treatment are known, but concerns regarding long-term complications are increasing. Follow-up observation results after GnRHa treatment cessation in female CPP patients up to adulthood showed that treatment (especially <6 years) was beneficial for final adul...

Chronic gonadotropin-releasing hormone agonist (GnRHa) administration is used where suppression of hypothalamic-pituitary-gonadal axis activity is beneficial, such as steroid-dependent cancers, early onset gender dysphoria, central precocious puberty and as a reversible contraceptive in veterinary medicine. GnRH receptors, however, are expressed outside the reproductive axis, e.g. brain areas s...

This study was aimed to evaluate the efficacy of a single administration of long-acting gonadotrophin-releasing hormone agonist (GnRHa) as compared with daily administrations of short-acting GnRHa in controlled ovarian hyperstimulation (COH) for in vitro fertilization and embryo transfer (IVF-ET) cycles. The mean dosage of recombinant follicle-stimulating hormone (rFSH) required for COH (2,354....

Background and purpose : Infertility with an incidence of about 15% has mainly been one of the community burdens that have even been threatening to the continuity of the family life. One of the most prevalent causes of women infertility is ovarian causes particularly PCOS. The aim of this study was to determine the outcome of IVF & ET in women with PCOS in comparison with tubal factor. Mat...

STUDY QUESTION Are there factors predicting the number of total and mature oocytes retrieved after controlled ovarian hyperstimulation (COH) utilizing a gonadotropin-releasing hormone (GnRH) antagonist protocol and a GnRH agonist (GnRHa) to induce oocyte maturation? SUMMARY ANSWER Peak estradiol (E₂) level, post-trigger LH and progesterone and the magnitude of LH rise are independent predicto...
