The present study was designed to investigate, in hyporesponder subjects, that required in a previous assisted reproductive technologies (ART) cycle follicle stimulating hormone (FSH) \>3500 International Unit (IU), the possibility to decrease through recombinant human luteinizing hormone (r-hLH) supplementation, the FSH amount per oocytes retrieved and in the mean time to improve the overall cycle outcome.
Recombinant human follicle stimulating hormone (r-hFSH), which totally lacks LH activity, is widely used to induce multiple follicle development in women under pituitary desensitization, in order to submit them to treatment with assisted reproduction techniques (ART). Clinical experience from hypogonadotropic-hypogonadic women suggests that while FSH alone is sufficient to induce follicle development, LH plays a significant part in final follicle maturation, estrogen synthesis and optimal endometrium growth. This was a phase III, multicentre, randomized, open-label comparative study to evaluate if the addition of r-hLH (Luveris) in a 2:1 ratio to FSH from day 8 of ovarian stimulation is able to decrease the total FSH dose and to improve cycle outcome in 250 infertile women undergoing ART, who required high FSH dose in a previous cycle (≥ 3500 IU). Subjects who have met all the inclusion criteria, achieved pituitary desensitization and started controlled ovarian hyperstimulation (COH) treatment with FSH, on stimulation day 8 (S8) received an identification number and will be allocated to one of the two following arms: Arm : FSH + r-hLH (2:1 ratio of FSH:r-hLH), Arm : FSH alone. Treatment with Luveris was commenced on day 8 (S8) and continued until injection of hCG or cancellation of the treatment cycle. Monitoring of stimulation, FSH dose escalation, criteria for injection of hCG, ovum pick up, embryo transfer and pregnancy confirmation took place according to standard management practice. The in-vitro fertilization (IVF) or intracytosolic sperm injection (ICSI) procedure, including luteal phase support, was performed according to each centres' normal procedures. The subjects were followed up and the treatment outcome (menstruation or pregnancy) was recorded. The delivery outcome for any pregnant subjects was recorded in the Case Report Form (CRF). Information on the delivery outcome for each pregnancy was collected. Information on adverse events was collected during the study period. OBJECTIVES The primary objective of the study was: To determine whether the addition of r-hLH (Luveris) from day 8 of ovarian stimulation reduces the FSH dose needed to obtain/retrieve each oocyte. The secondary objectives of the study were: * To determine whether the addition of Luveris to FSH at day 8 of ovarian stimulation improves cycle outcome based on secondary endpoints * To determine the safety of Luveris in this indication

Total Dose of Follicular Stimulating Hormone (FSH) for Retrieved Oocytes
Time frame: Baseline (Stimulation day 8 [S8]) until hCG day
Mean Total Follicle Stimulating Hormone (FSH) and Recombinant Human Luteinizing Hormone (r-hLH) Dose
Time frame: Baseline (S8) until hCG day
Mean Number of Ovarian Stimulation Days
Time frame: Baseline (S8) until hCG day
Change From Baseline in Oestradiol (E2) Levels at Human Choriogonadotropin (hCG) Day
Time frame: Baseline (S8) and hCG day
Mean Total Number of Retrieved Oocytes
Mean number of oocytes retrieved on the day of ovum pick up (OPU) was counted. Oocyte retrieval is a technique used in in-vitro fertilization in order to remove oocytes from the ovary of the female, enabling fertilization outside the body.
Time frame: 34-36 hours post-hCG (OPU)
Mean Number of Mature Oocytes (Metaphase II)
Mean number of metaphase II oocytes was counted for participants undergoing ovum pick up for IntraCytoplasmic Sperm Injection (ICSI). ICSI is a procedure in which a single spermatozoon is injected into the oocyte cytoplasm. Metaphase II stage of the oocyte was classified as the time at which the first polar body was observed microscopically. Metaphase II oocytes are a sub-group of the total number of oocytes.
Time frame: 34-36 hours post-hCG (OPU)
Fertilization Rate
Fertilization rate was measured as the ratio between number of fertilized oocytes and number of inseminated oocytes (maximum 3).
Time frame: 12-18 day post-hCG and/or Week 7
Number of Obtained Embryos
Total number of obtained embryos with maximum 3 inseminated oocytes was calculated.
Time frame: Day 3 post-hCG (Embryo transfer [ET])
Number of Transferred Embryos
Embryo transfer is the procedure in which one or more embryos are placed in the uterus or Fallopian tube.
Time frame: Day 3 post-hCG (ET)
Percentage of Participants With Pregnancy
Time frame: 12-18 day post-hCG and/or Week 7
Percentage of Participants With Clinical Pregnancy
Clinical pregnancy is defined as pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs or definitive clinical signs of pregnancy. It includes ectopic pregnancy.
Time frame: 12-18 day post-hCG and/or Week 7
Percentage of Participants With Implantation
Implantation is the attachment and subsequent penetration by the zona-free blastocyst (usually in the endometrium) that starts five to seven days after fertilization.
Time frame: 12-18 day post-hCG and/or Week 7
Number of Participants With Ovarian Hyper Stimulation Syndrome (OHSS)
OHSS is an exaggerated systemic response to ovarian stimulation characterized by a wide spectrum of clinical and laboratory manifestations. It is classified as mild, moderate or severe according to the degree of abdominal distention, ovarian enlargement and respiratory, haemodynamic and metabolic complications.
Time frame: Baseline (S8) until 12-18 day post-hCG and/or Week 7
Number of Cycles Cancelled Due to Risk of OHSS
OHSS is an exaggerated systemic response to ovarian stimulation characterized by a wide spectrum of clinical and laboratory manifestations. It is classified as mild, moderate or severe according to the degree of abdominal distention, ovarian enlargement and respiratory, haemodynamic and metabolic complications.
Time frame: Baseline (S8) until 12-18 day post-hCG and/or Week 7
