Many controlled clinical trials and numerous systematic reviews of these studies have been published. (meridianhealthnc.com)
Total-testosterone1
METHODS: Several FSH, LH, total testosterone and inhibin B assays and FSH ß gene sequencing were performed. (bvsalud.org)
Infertility12
Studies set in infertility clinics have the advantage of investigating obesity trends within infertile populations whereas populations of unselected healthy men across BMI categories enable evaluation of the association between obesity and fertility without a preconceived bias. (medscape.com)

Secondary infertility refers to infertile couples who have been able to achieve pregnancy at least once before (with the same or different sexual partner). (uroweb.org)
In 50% of involuntarily childless couples, a male-infertility-associated factor is found, usually together with abnormal semen parameters [ 1749 ]. (uroweb.org)
In 30-40% of cases, no male-associated factor is found to explain the underlying impairment of sperm parameters and historically was referred to as idiopathic male infertility. (uroweb.org)
Unexplained male infertility is defined as infertility of unknown origin with normal sperm parameters and partner evaluation. (uroweb.org)
It is now believed that idiopathic male infertility may be associated with several previously unidentified pathological factors, which include but are not limited to endocrine disruption as a result of environmental pollution, generation of reactive oxygen species (ROS)/sperm DNA damage, or genetic and epigenetic abnormalities [ 1753 ]. (uroweb.org)
Advanced paternal age has emerged as one of the main risk factors associated with the progressive increase in the prevalence of male factor infertility [ 1754-1761 ]. (uroweb.org)
Table 52 summarises the main male-infertility-associated factors. (uroweb.org)
The purpose of this study was to determine the causes of infertility in patients, the appropriate ART treatment, and their prognosis in terms of pregnancy. (bvsalud.org)
OBJECTIVE: Congenital FSH deficiency is an exceptional cause of male infertility most often attributed to FSH ß gene mutations. (bvsalud.org)
Sperm2
Possible explanations why these population studies are not more consistent could include lack of sensitivity of BMI as a measurement of adiposity, presence of subfertility, which may manifest by more subtle changes in testicular/sperm physiology not captured by traditional semen assessments, and finally, heterogeneity within the overweight/obese populations. (medscape.com)
We report the exploration of two young men aged 26 and 27 years with severe sperm abnormalities, moderate testicular hypotrophy and isolated FSH deficiency. (bvsalud.org)
Fertility1
These men present with no previous history of diseases affecting fertility and have normal findings on physical examination and endocrine, genetic and biochemical laboratory testing, although semen analysis may reveal pathological findings (see Section 11.3.2). (uroweb.org)
Levels1
The few published cases report azoospermia, severe testicular hypotrophy and normal testosterone levels associated with normal virilization. (bvsalud.org)
Management2
Likewise, advanced maternal age must be considered in the management of every infertile couple, and in the subsequent decisions in the diagnostic and therapeutic strategy of the male partner [ 1762 , 1763 ]. (uroweb.org)
Research Question: Unlike in men, a very limited number of studies were focused on the specificity of ART management of cystic fibrosis (CF) in women. (bvsalud.org)
Evaluation1
For this reason, in all infertile couples the male should undergo medical evaluation by a urologist trained in male reproduction. (uroweb.org)
Report1
Many population studies are limited by the small sample size of the obese study population, and tend to report overweight/obese data as a single group, which would be expected to reduce the strength of the associations measured. (medscape.com)
Design1
Design: We conducted a multicentre analytical case-control study including CF women who were age-matched to non-CF women. (bvsalud.org)
Results1
RESULTS: 26 patients from 15 unrelated families were studied (18 women, median age 43 years). (bvsalud.org)
