One in six couples worldwide is affected by infertility, which defined as the inability to conceive after one year or more of regular and unprotected intercourse. It has been stated that 48.5 million couples in the world, with unprotected coitus, suffer from infertility. In about 50% of them, the infertility is due to female factors and diseases associated with the female reproductive system. Epidemiological studies show that 10 to 15% of all married couples are estimated to have infertility problems in the Middle East. Lebanon, in particular, is characterized with traditional and westernized lifestyles; It has high rates of smoking and caffeine intake, pollution and high rates of consanguinity marriage (11 to 17%), which affect considerably the conception rate. The desire to procreate is naturally present in women all over the world. Due to various advances in medical procreation techniques, it has become possible for many women to realize their hope. Women were more likely to be psychologically distressed to infertility and suffer from poor quality of life more than men once they are diagnosed as infertile. The causes of female infertility can have a genetic, anatomical or physiological origin. Among the most common genetic causes of female infertility are the chromosomes abnormalities: the numbers of X chromosomes, homogeneous or mosaic; other abnormalities are reciprocal translocations, Robertsonian translocations, inversions, supernumerary markers or abnormalities of the X chromosome structure. In such cases, no treatment and procreation require an egg donation. But the main causes of female infertility are physiological and anatomical, such as ovulatory disorders (25%), endometriosis (15%), pelvic adhesions (12%), tubal blockage (11%), other tubal abnormalities (11%), hyperprolactinemia (7%) and some minor causes. In addition, leiomyomas, fibroma, polyps, and tubal disease, may reduce fertility. In addition came the environmental factors (drugs, pesticides, food, tobacco ...) and there is an increase in the percentage of infertile women with advancing female age. A French national survey on lifestyles and toxic factors in infertile couples showed that in women, tobacco generates a risk twice as high as being infertile, a decrease in the ovarian reserve where the level of anti-Mullerian hormone (AMH) decreases, irregular short cycles and dysmenorrhea are also found in smokers. In addition, products contained in tobacco such as cotinine, cadmium and hydrogen peroxide are found in the follicular fluid and would be responsible for an alteration of the recovery of oocyte meiosis. Couples who have problems with conception are referred to a medically assisted procreation (MAP) for fertility treatments. These treatments can be very stressful both psychologically and physically. Indeed, the numerous medical appointments and examinations, as well as the many bereavements and failures, experienced following repeated attempts at conception can to consume the married, social and professional life of couples. In addition, fertility issues require significant financial resources to cover the costs of fertility treatments, but also those related to the maternal and fetal complications of pregnancy, which are more frequent in the case of MAP pregnancies than in spontaneous conception. Control of the ovarian stimulation is the key component of assisted reproductive technologies (ART) that have shifted the clinical practice of natural mono-follicular cycles into multi-follicular stimulated cycles. The increase in the number of follicles, and consequently the number of oocytes recovered, improved pregnancy rates in women undergoing In Vitro Fertilization (IVF) / Intra-Cytoplasmic Sperm Injection (ICSI), not only by increasing the number of available embryos but also by allowing embryo culture extended and allowing the selection of higher quality embryos to be transferred. However, several studies have addressed the issue of the optimal number of oocytes recovered following controlled ovarian stimulation (COS) for IVF / ICSI and demonstrated that the ovarian response is independently related to Live Birth Rate (LBR) after IVF / ICSI. Many new treatment modalities for ovarian stimulation have been introduced over the years - often with insufficient evidence of safety and efficacy - using different compounds and regimens for ovarian stimulation, triggering oocyte maturation, interventions preceding stimulation supplementation phase. The most important clinical challenge is to find the right balance between improving the chances of success (birth of a healthy child), a reasonable cost, acceptable discomfort for the patient, and a minimal complication rate. New developments make ovarian stimulation less intense and more individualized. The choice of the ovarian stimulation protocol is one of the most important steps in IVF/ICSI treatment. This study aims to identify and evaluate ovarian stimulation protocols applied to different patients with different causes of female infertility prior to medically assisted procreation techniques in order to know if there is a relationship between a given protocol and the result obtained for each class of infertility. Therefore, 360 ICSI in 200-300 couples will be studied in order to evaluate the link between ovarian stimulation protocols and outcomes of ICSI. The population will be divided into 3 groups: Group "OD" for ovulation disorders caused by endocrine disorders such as the polycystic ovarian syndrome (PCOS) and/or premature ovarian failure (POF) Group "TD" for tubal disorders caused by previous ectopic pregnancy, salpingectomy, tubal obstruction and/or hydrosalpinx Group "UCD" for uterine and cervical disorders caused by fibroids, endometriosis, infection and/or congenital uterine anomaly (CUA)
