Serum follicle stimulating hormone (FSH) is routinely measured when evaluating the infertile male for intracytoplasmic sperm injection (ICSI). However, among the sperm parameters, only its relationship with sperm concentration is well documented. Few investigations concern the relationship between FSH and sperm motility and morphology, and the results of ICSI. A retrospective study of 316 coupl...

Urogenital infection can influence the fertilization potential of the spermatozoa, which may lead to male infertility. The symptomatic urethiritis can change the semen parameters, however the role of asymptomatic urethirtis in fertility is still obscure. In this descriptive investigation, a total of 148 samples from urethra and semen of fertile as well as 146 samples from urethra and semen of i...

AIM To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups. METHODS Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay (ELISA) method in 80 infertile men equally divided into four groups: non-obstructive azoospermia (NOA), obstructive azoospermia (OA), congenital bilateral absent vas deferens (CBVAD)...

Recently, infertility treatment-related psychological effects are receiving increased attention. However, whether sexual satisfaction is reduced amongst infertile couples remains to be elucidated. In this study, sexual satisfaction of Japanese infertile couples was assessed using a validated questionnaire designed to assess the male and female partner individually, and the couple as a whole for...

Background: The evaluation of the infertile male includes a thorough history taking, physical examination Semen analysis, hormonal array and search for anti sperm antibody. Additional tests include Trans rectal ultrasound, vasography and testicular biopsy. The latter is particularly useful in cases of azoospermia or oligozoospermia and normal endocrine function. Objective: To identify and categ...

BACKGROUND Few studies have been conducted on the infertility problems in Iran. This study aimed to investigate the prevalence of infertility problems and related factors in Iranian infertile patients. MATERIALS AND METHODS In this cross sectional study, 405 infertile patients referred to Royan Institute, Tehran, Iran, between 2014 and 2015, were selected by simple random sampling. Participan...

In a prospective study, the prevalence of infection with Chlamydia trachomatis and Ureaplasma urealyticum was evaluated in the semen of 92 asymptomatic male partners of infertile couples using polymerase chain reaction and culture, respectively. The results were compared with the detection of serologically specific antibodies. U. urealyticum and C. trachomatis were detected in 12 (13%) and 10 (...

BACKGROUND Thrombophilia-related mutations, such as coagulation factor V Leiden and factor II (G20210A), have been associated with female infertility due to spontaneous abortions during pregnancy. The possible role of mutations of these two factors in male infertility has not been studied to date. MATERIALS AND METHODS A total of 208 unrelated Greek men were investigated, including 108 infert...

Aberrations in reproductive fitness may be a harbinger of medical diseases in men. Existing data suggest that female infertility is associated with autoimmune disorders; however, this has not been examined in men. As immune surveillance and hormonal factors can impact male fertility and autoimmunity, we sought to determine the association between male infertility and incident autoimmune disorde...

Infertility is a major health problem today, affecting about 15.0% of couples trying to have a child. Impaired fertility of the male is causative in 20.0% of infertile couples and contributory in up to another 30.0-40.0%. Infertility already affects about 5.0-7.0% of the general male population and may further increase in the future, considering the apparent trend of declining sperm count in in...
