Intervention 1: In the first group patients treated with a dose of 150 International Unit (IU) recombinant Follicular Stimulating Hormone (rFSH) per day. Treatment with rFSH will continue until the creation of the oocytes. When at least two or three follicles 18 millimeter to 20 millimeter in size were formed; 100 IU human Chorionic Gonadotropin (hCG) will inject. Thirty six hours later ovarian puncture is performed. Intervention 2: In the second group patients treated with a dose of 150 International Unit (IU) recombinant Follicular Stimulating Hormone (rFSH) per day. When the follicle size become 14 millimeter, rFSH dose reduce to 75 IU per day and treatment starts with 100 IU human Chorionic Gonadotropin (hCG) per day. When at least two or three follicles 18 millimeter to 20 millimeter in size were formed; 100 IU hCG will inject. Thirty six hours later ovarian puncture is performed. Intervention 3: In the third group patients treated with a dose of 150 International Unit (IU) recombinant Follicular Stimulating Hormone (rFSH) per day. When follicle size become 14 millimeter, treatment with rFSH stops and patient treat with 200 IU human Chorionic Gonadotropin per day. When at least two or three follicles 18 millimeter to 20 millimeter in size were formed; 100 IU hCG will inject. Thirty six hours later ovarian puncture is performed.
