background : today, infertility is a major medical problem and its prevalence is increasing worldwide. infertility affects men and women of reproductive ages. in addition, infertile couples encounter many emotional and mental problems. the theory of planned behavior is a theory that explains the process of adopting appropriate behaviors. the aim of this study was to determine the predictive pow...

BACKGROUND Oxidative stress in reproductive system leads to sperm DNA damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. Antioxidants such as carotenoids function against free radical damages. OBJECTIVE The aim of this study was to determine the levels of lycopene, beta-carotene and retinol in se...

Ureaplasma spp. have gained increasing recognition as pathogens in both adult and neonatal patients with multiple clinical presentations. However, the clonality of this organism in the male population and infertile couples in China is largely unknown. In this study, 96 (53 U. parvum and 43 U. urealyticum) of 103 Ureaplasma spp. strains recovered from genital specimens from male patients and 15 ...

Concept of autoimmune basis of infertility is still controversial, particularly regarding the presence of non-organ specific autoantibodies. Non-organ specific anticardiolipin (aCL) and antithyroglobulin (TgAt) antibodies were detected in infertile women. Both partners were evaluated according to the criteria of The American Society for Reproductive Medicine. All the results were normal in case...

OBJECTIVE To establish cutoff value, sensitivity, specificity and intra- and interobserver variability of total antioxidant capacity (TAC) in seminal plasma from healthy donors (controls) and infertile patients. DESIGN Seminal plasma from proven fertile donors (n = 55), nonproven fertile donors (n = 45), and infertile patients (n = 42) were examined for TAC level. SETTING Reproductive resea...

BACKGROUND Infertility is an emergent issue in India. Until recently, very few studies have understood the patterns and consequences of infertility in India. Family planning programs in India also viewed exclusively the patterns and determinants of overfertility rather than infertility. Furthermore, there is the lack of information about treatment seeking behavior of infertile couples. Therefor...

BACKGROUND Reduced ovarian reserve predicts poor ovarian response and poor suc- cess rates in infertile women who undergo assisted reproductive technology (ART). Ovarian reserve also decreases with age but the rate of decline varies from one woman to another. This study aims to detect differences in ovarian reserve as measured by basal serum follicle stimulating hormone (FSH) and anti-Müllerian...

The purpose of this study was to determine whether normospermic infertile men have high seminal oxidative stress, using 3 measures of oxidative stress: reactive oxygen species (ROS), total antioxidant capacity (TAC), and a composite ROS-TAC score. Forty-three normospermic men without leukocytospermia and 19 healthy donors who came to our infertility clinic were included. Patients were categoriz...

BACKGROUND For a long time, infertility has been one of the most sequels in medical sciences with microbial agents as one group of its causes. The possible etiological role of Chlamydia trachomatis in infertility was suggested years ago, but it has not yet been proved completely. To decrease the severe involvements of C. trachomatis infections, screening by efficient diagnostic methods are nece...

BACKGROUND Chlamydia trachomatis infection is a worldwide-distributed sexually transmitted infection that may lead to infertility. OBJECTIVES This study aims to report the prevalence of Chlamydia trachomatis infection among infertile women in Saudi Arabia. PATIENTS AND METHODS A community-based study carried out at the obstetrics and gynecology clinic at Jazan General Hospital, Saudi Arabia...
