BACKGROUND The objective of this study was to identify the prognostic factors that influence the outcome of ovarian stimulation with intrauterine insemination (IUI) cycles in couples with different infertility etiology. MATERIALS AND METHODS This retrospective study was performed in data of 1348 IUI cycles with ovarian stimulation by clomiphene citrate (CC) and/or gonadotropins in 632 women w...

BACKGROUND Psychological factor alters fertility hormones and contributes to male infertility. Anxiety and depression are common manifestations of psychological distress. Cytochrome P-4501A1 (CYP1A1) metabolizes xenobiotics and fertility hormones that influence male fertility. The effect of CYP1A1 polymorphism on male fertility has remained controversial. The present study was designed to asses...

Male are the sole cause of infertility in approximately 20% of infertile couples and are an important contributing factor in another 20-40% of couples with reproductive failure. Male infertility can result from a variety of causes. Some, like ductal obstruction and hypogonadotropic hypogonadism, can be accurately defined and effectively treated. Genetic abnormalities can cause infertility by in...

Infertility is one of the most serious social problems facing advanced nations. In general, approximate half of all cases of infertility are caused by factors related to the male partner. To date, various treatments have been developed for male infertility and are steadily producing results. However, there is no effective treatment for patients with nonobstructive azoospermia, in which there is...

BACKGROUND Our previous studies have demonstrated the cystic fibrosis transmembrane conductance regulator (CFTR) is important for capacitation and male fertility in mouse and guinea pig spermatozoa. However, the exact function of CFTR on human sperm fertilizing capacity, and correlation with sperm quality has not been established. The present study may shed light on some unexplained male infert...

background: it is established that sperm dna integrity is essential in fertilization and normal embryo and fetal development. routine semen analysis gives an approximate evaluation of the functional competence of spermatozoa, but does not always reflect the quality of sperm dna. therefore, the evaluation of sperm dna integrity, in addition to routine sperm parameters, could add further informat...

Aim: Given the increasing usage of cell phones (6.9 billion subscriptions globally) and heterogeneous reports, this study aimed to determine phone effect as non-ionizing radiation on level testosterone hormone sperm parameters in male rats. Material Methods: Twenty-five matured Wistar rats were randomly allocated five groups with same body weights. Radiofrequency for exposed was 1 h/day call, 2...

With the introduction of intracytoplasmic sperm injection (ICSI), couples with severe male factor infertility have been able to achieve fertilization and clinical pregnancy rates comparable to other in vitro fertilization patients. However, despite the utilization of microsurgical sperm injection techniques, failure of fertilization still occurs in a few patients. How such fertilization failure...
