Testicular2
Cryptorchidism, hypospadias, testicular cancer and poor semen quality make up the syndrome known as testicular dysgenesis syndrome. (wikipedia.org)

Many controlled clinical trials and numerous systematic reviews of these studies have been published. (meridianhealthnc.com)
Sperm7
Semen quality involves both sperm quantity and quality. (wikipedia.org)
A 2017 review and meta-analysis found sperm counts among Western men (i.e. men in Australia, Europe, New Zealand, and North America) declined 50-60% between 1973 and 2011, with an average decline of 1.4% per year. (wikipedia.org)
The decline in sperm count among men in South America, Asia, and Africa is less than men in Western countries, though the amount of decline in these regions is uncertain. (wikipedia.org)
Although it is possible for men to father children into old age, the genetic quality of sperm, as well as its volume and motility, all typically decrease with age. (wikipedia.org)
In men with a normal level of sperm production (normozoospermia), the percentage of sperm DNA fragmentation is positively correlated with age, and inversely correlated with progressive sperm motility. (wikipedia.org)
While advanced age can be a possible factor in sperm motility and health, the sperm of men below 20 years of age has likewise been linked to an increase in birth defects such as neural tube defects, hypospadias, cystic kidney, and Down syndrome. (wikipedia.org)
For transgender adults assigned male at birth, FP is usually achieved via a masturbatory sample and sperm cryopreservation. (bvsalud.org)

Effects1
The majority of studies using such devices fails to show effects beyond a placebo response. (meridianhealthnc.com)
Semen analyses were performed by trained andrologists per World Health Organization guidelines and included semen volume, sperm concentration, sperm motility, and total motile sperm count (TMSC). (klinikfarmakoloji.com)
Abnormal1
In 50% of involuntarily childless couples, a male-infertility-associated factor is found, usually together with abnormal semen parameters [ 1749 ]. (uroweb.org)
Laboratory1
PURPOSE: Sperm DNA fragmentation (SDF) is a functional sperm abnormality that can impact reproductive potential, for which four assays have been described in the recently published sixth edition of the WHO laboratory manual for the examination and processing of human semen. (bvsalud.org)
Parameters4
Male obesity and infertility: observational studies of sperm parameters and BMI. (medscape.com)
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)
The Wilcoxon rank sum test was used to compare pre- and postvaccination semen parameters. (klinikfarmakoloji.com)
Infertility6
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)
Support relationship between obesity and male infertility? (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)
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)

Sperm concentration1
Of these 8, 7 men had increased sperm concentration to normozoospermic range at follow-up (median concentration, 22 million/mL [IQR, 17-25.5]), and 1 man remained oligospermic. (klinikfarmakoloji.com)
Genetic1
Although it is possible for men to father children into old age, the genetic quality of sperm, as well as its volume and motility, all typically decrease with age. (wikipedia.org)
Likewise2
While advanced age can be a possible factor in sperm motility and health, the sperm of men below 20 years of age has likewise been linked to an increase in birth defects such as neural tube defects, hypospadias, cystic kidney, and Down syndrome. (wikipedia.org)
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)
Semen quality involves both sperm quantity and quality. (wikipedia.org)
Many products that come into direct contact with spermatozoa lack adequate testing for any adverse effect on semen quality. (wikipedia.org)

Sample1
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)
Evaluation1
For this reason, in all infertile couples the male should undergo medical evaluation by a urologist trained in male reproduction. (uroweb.org)
