The effects of treatment of patients with gonadotrophin-releasing hormone analogue (GnRHa) combined with purified follicle stimulating hormone (FSH) for in-vitro fertilization (IVF) were investigated in detail to determine the influences of different administration routes and the degree of suppression of luteinizing hormone (LH). Responses to exogenous gonadotrophins were studied in infertile w...

It is now known that gonadotrophin-releasing hormone analogues (GnRHa) are extremely efficient at reducing uterine fibroid volume and reversing the related symptomatology. However, the fibroids tend to return to their pretreatment size about 6 months after discontinuing treatment. GnRHa treatment cannot be continued indefinitely due to its potential complications and high cost. It is therefore ...

BACKGROUND Triggering ovulation by GnRH agonist (GnRHa) in GnRH antagonist IVF protocols coupled with adequate luteal phase support has recently been suggested as a means to prevent ovarian hyperstimulation syndrome (OHSS). Our objective was to examine the outcome of fresh embryo transfer (f-ET) after triggering ovulation by GnRHa and providing intensive luteal phase supplementation, compared w...

OBJECTIVE The aim of the study reported here was to investigate the protective effect of gonadotropin-releasing hormone analog (GnRHa) against cyclophosphamide (CTX)-induced gonadotoxicity. METHODS Eighty Fischer 344 rats were divided randomly into four groups (20 per group). One group received normal saline, one GnRHa, one CTX, and one GnRHa+CTX. Several parameters were used to observe the o...

PURPOSE Gonadotropin-releasing hormone agonist (GnRHa) is known for improving final adult height in patients with central precocious puberty (CPP). This study aimed to investigate the age of menarche and near adult height in girls with CPP who had been treated with GnRHa. METHODS In this retrospective study, we reviewed the medical records of 71 Korean girls with CPP who had started menarche ...

The goal of our study was to assess whether the total dose of gonadotrophin-releasing hormone agonist (GnRHa) administered affects the success of an in-vitro fertilization (IVF) programme. A retrospective analysis was performed on a total of 72 IVF cycles carried out on 70 patients with different causes of infertility included in our assisted reproduction programme. Cycles were divided into two...

The use of gonadotrophin-releasing hormone analogues (GnRHa) has resulted in improved pregnancy rates in in-vitro fertilization (IVF) treatment cycles. Traditionally, short-acting analogues have been employed because of concerns over long-acting depot preparations causing profound suppression and luteal phase defects adversely affecting pregnancy and miscarriage rates. We randomized 60 IVF pati...

PURPOSE Although combining aromatase inhibitors (AI) with gonadotropin-releasing hormone agonists (GnRHa) is becoming more common, it is still not clear if GnRHa is as effective as bilateral salpingo-oophorectomy (BSO). MATERIALS AND METHODS We retrospectively analyzed data of 66 premenopausal patients with hormone receptor- positive, human epidermal growth factor receptor 2-negative recurren...
