Title: Short Versus Long IVF-treatment. A Prospective, Consecutive and Randomized Comparative Study
Brief Summary: Purpose: Comparing a GnRH agonist and an antagonist protocol for IVF/ICSI with regard to

1. frequency of ovarian hyperstimulation syndrome (OHSS) (1. outcome measure)
2. quality of life (2. outcome measure)
3. live birth rate (2. outcome measure)
4. gene expression profiles of granulosa and cumulus cells, and concentrations of estradiol and vascular endothelial growth factor in follicular fluid(not only compared between GnRH agonist and antagonist protocol, but also between patients with OHSS and no OHSS and patients becoming pregnant and not becoming pregnant (2. outcome measure), and
5. number of oocytes removed per treatment, number of embryo transfers per treatment and number of spontaneous abortions per treatment (these three parameters are tertiary outcome measures).

In addition to the above mentioned efficacy outcome measures the safety outcome measure "frequency of known side-effects" will be compared between the two protocols.

6. Have an early follicular phase (Day 2-4) serum level of basal FSH lower than or equal to 12 International Unit per Liter (IU/L) measured in the center's local laboratory during the screening period (i.e. within 2 months prior to down-regulation start)
7. Presence of both ovaries
8. Normal uterine cavity, which in the investigator's opinion is compatible with pregnancy
9. Have a negative cervical papanicolaou (PAP) test within the last 6 months prior to randomization
10. Have at least 1 wash-out cycle (defined as greater than or equal to 30 days since the last dose of clomiphene citrate or gonadotrophin treatment) since the last ART cycle and/or clomiphene citrate or gonadotrophin treatment prior to starting gonadotropin releasing hormone (GnRH) agonist therapy
11. Willing and able to comply with the protocol for the duration of the trial
12. Have given written informed consent, prior to any trial-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to her future medical care

Exclusion Criteria:

1. Have greater than or equal to 2 previous ART cycles with a poor response to gonadotrophin stimulation (defined as lower than or equal to 5 mature follicles and/or lower than or equal to 3 oocytes collected) or have greater than or equal to 2 previous ART cycles with a hyper response (defined as greater than or equal to 25 oocytes retrieved)
2. Any medical condition, which in the judgment of the investigator may interfere with the absorption, distribution, metabolism or excretion of the drug. In case of doubt, the subject in question should be discussed with Merck Serono's Medical responsible
3. Have previous severe ovarian hyperstimulation syndrome (OHSS)
4. Polycystic ovary syndrome (PCOS; Rotterdam criteria) to reduce the risk of the occurrence of OHSS
5. Presence of endometriosis requiring treatment
6. Uterine myoma requiring treatment
7. Any contraindication to being pregnant and/or carrying a pregnancy to term
8. Extra-uterine pregnancy within the last 3 months prior to screening
9. History of 3 or more miscarriages (early or late miscarriages) due to any cause
10. Tumors of the hypothalamus and pituitary gland
11. Ovarian enlargement or cyst of unknown etiology
12. Ovarian, uterine or mammary cancer
13. A clinically significant systemic disease
14. Known infection with Human Immunodeficiency Virus (HIV), Hepatitis B or C virus in the trial subject or her male partner,
15. Abnormal gynecological bleeding of undetermined origin
16. Known allergy or hypersensitivity to human gonadotrophin preparations,
17. Any active substance abuse or history of drug medication or alcohol abuse in the past 5 years prior to the screening visit
18. Entered previously into this trial or simultaneous participation in another clinical trial
D: Inclusion Criteria:

* Informed Consent Documents signed prior to screening evaluations related to this protocol
* Participation in the pivotal efficacy trial (trial 000004/ESTHER-1)
* Anti-FSH antibody results from baseline and at least one post-dosing assessment in the previous cycle(s) available.
* Having undergone the oocyte retrieval procedure, or having had cycle cancellation prior to oocyte retrieval due to poor ovarian response or excessive ovarian response, in the previous cycle(s).
* Failure to achieve ongoing pregnancy in the previous cycle(s).

Exclusion Criteria:

* Non-compliance to protocol compliance in the previous cycle(s).
* Having undergone any stimulation with gonadotropins since the end-of-trial / end-of-cycle visit in the previous cycle
* One or more follicles ≥10 mm observed on the transvaginal ultrasound prior to start of dosing on stimulation day 1
