Background: Polycystic ovarian syndrome (PCOS) is a medical condition that affects women's menstrual cycles, fertility, hormone levels, and physical appearance. PCOS is thought to be one of the leading causes of female infertility, and is the reason of more than 75% of cases of anovulatory infertility. Materials and Methods: In this article, we review the different aspects of PCOS includin...

Infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. There is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. Choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...

The majority of male infertility is idiopathic. However, there are multiple known causes of male infertility, and some of these causes can be treated medically with high success rates. In cases of idiopathic or genetic causes of male infertility, medical management is typically empirical; in most instances medical therapy represents off-label use that is not specifically approved by the FDA. Un...

Cryptorchidism is the most frequent defect of the male urogenital tract at birth. It represents a risk factor for primitive testiculopathy associated with long-term complications (infertility, testicular neoplasia, and hormonal changes). An only consensus exists: "children with bilateral cryptorchidism who are not treated in early age are certainly set to become infertile". The majority of Auth...

Azoospermia, defined by the absence of sperm in the ejaculate, is estimated to affect up to 1% of men in the general population. Assisted reproductive technologies have revolutionized the treatment of infertility, and some azoospermic men, those with a post-meiotic defect, can conceive following the use of viable spermatoza recovered from testicular or epididymal biopsies. Although male inferti...

Meta-analysis Polymorphism Studies of the relationship between male infertility and CYP1A1 polymorphisms are inconclusive. To drive a more precise estimation, we performed a meta-analysis based on 1,060 cases and 1,225 controls from 7 published casecontrol studies. PubMed and CNKI literature search were conducted to identify all eligible studies investigating such a relationship. Crude odds rat...

The prevalence of infertility is varies worldwide ranging from 3% to 7%. The consequences of infertility are societal repercussions, personal suffering, psychological effects, clinical depression and sexual dysfunction. Therefore, the aim of the present study was a systematic review of the literature to determine the main risk factors of female infertility. MEDLINE, EMBASE and Cochrane Database...

BACKGROUND Infertility is considered as a major health care problem of different communities. The high prevalence of this issue doubled its importance. A significant proportion of infertility have been related to environmental conditions and also acquired risk factors. Different environmental conditions emphasized the need to study the different causes of infertility in each area. OBJECTIVE T...

Background: We are convinced that better infertility treatment will only be achieved with a better under understanding of the molecular mechanisms specific to each patient. To that effect we want to indentify genes involved in male infertility. Materials and Methods: We screened cohorts of infertile men to identify the cause of their infertility. Results: Our team has identified and caracterize...
