Detailed Description
Growth hormone (GH; Saizen®) is indicated for the treatment of growth hormone deficiency in both children and adults, as well as for Turner's Syndrome, chronic renal failure, and children born short for gestational age.
In animal studies, growth hormone has been shown to be important in early antral follicle recruitment, subsequent follicular growth, and oocyte maturation. Together with insulin-like growth factor-1 (IGF-1), growth hormone is essential early on in the recruitment of primordial follicles in the growing pool (Slot et al 2006, Wandji et al 1992, Donadeu & Peterson 2008, Scaramuzi et al 2006, Liu et al, 1998).
Two recent meta-analyses have concluded that the addition of growth hormone during the ovarian stimulation phase of in vitro fertilization (IVF) cycles in poor responders will result in an increased probability of clinical pregnancy (Kolibianakas et al, 2009 and Ahmad et al, 2009). However, these studies have investigated the role of growth hormone in IVF when starting growth hormone injections with the initiation of gonadotropin stimulation. This may be too late to show an effect as GH may have more of an impact in the month prior to stimulation when primordial follicles are in the recruitment phase. Adding growth hormone in the month prior to stimulation with gonadotropins, as well as during stimulation phase may improve IVF outcomes by increasing the number of antral follicles that are recruited in the month prior to a stimulated cycle, and may ultimately improve the response to gonadotropin stimulation.
Starting growth hormone prior to stimulation has been studied in one previous publication (Kucuk et al, 2008), and showed that by starting growth hormone on day 21 of the menstrual cycle preceding gonadotropin stimulation, and continuing co-treatment with growth hormone until human chorionic gonadotropin (hCG) trigger resulted in a significantly higher number of fertilized oocytes when compared to a control group receiving no growth hormone (4.4 +/-1.8 vs 1.5 +/-0.9; p<0.001).
The addition of growth hormone to an IVF treatment protocol is directed at those infertile women who have previously undergone an IVF cycle on maximal doses of gonadotropins with a poor ovarian response. This study is aimed at improving IVF success in this population of women at the Ottawa Fertility Centre.
The purpose of this study is to determine if the addition of growth hormone both in the month prior to gonadotropin stimulation and during the active phase of stimulation, will result in an increased number of mature oocytes retrieved in previously poor responders during an IVF cycle.

---|---|
Active Comparator: Group A - Control group
Group A (n=10; control group) will receive the "patch protocol" consisting of the 100ug estrogen patch (Estradot), a Gonadotropin Releasing Hormone (GnRH) antagonist (Cetrotide; 0.25mg/d), and gonadotropin stimulation with 412 IU of recombinant follicle stimulating hormone (r-FSH; Gonal F) and 150 IU of recombinant luteinizing hormone (r-LH; Luveris).

Group A (n=10; control group) will receive "patch protocol": 100ug estrogen patch (Estradot), Gonadotropin releasing hormone (GnRH) antagonist (Cetrotide; 0.25mg/d), gonadotropin stimulation 412 IU recombinant follicle stimulating hormone (r-FSH; Gonal F) and 150 IU of recombinant luteinizing hormone (r-LH; Luveris).
With 3 or more follicles at mean diameter equal to or greater than 17mm, urinary human chorionic gonadotropin (u-hCG) 10,000 IU self-injected to complete final maturation of oocytes.
Egg retrieval will occur 36 hours after hCG injection.
Eggs fertilized by standard IVF or intra-cytoplasmic sperm injection (ICSI) depending on semen parameters.
Embryos cultured to day 2 and the best 2-4 will be transferred back under ultrasound guidance.
Surplus embryos will be frozen as per clinic protocol.
Luteal support: Endometrin 100mg vaginally three times daily, starting on the day of egg retrieval and continuing until menses or positive serum beta-hCG, then stopped.
|
Experimental: Group B - treatment group
Group B will consist of 30 subjects.
In addition to the same hormone stimulation "patch protocol" as Group A, subjects will be treated with growth hormone 10 IU (3.33mg) per day by subcutaneous injection starting day 1 of the last menstrual period in the month prior to gonadotropin stimulation, and will continue daily until the day of human chorionic gonadotropin (hCG) injection.
|
Subjects in this trial will use a 3.33mg vial (1 vial =10 IU) by daily subcutaneous injection.
This will start on day 1 of the menstrual cycle preceding the stimulation phase of an IVF cycle, and will continue until the day of the human chorionic gonadotropin (hCG) trigger (approximately 5-6 weeks)
