“…For example, almost three-quarters of previous studies of reproductive function in middle-aged men did not consider the duration of abstinence before semen analysis (20,21). In our study, the recommended period of abstinence (10,17) was no shorter than 48 hours and no longer than seven days for all participants.…”

“…Although several studies have shown that sperm quality in men decreases with age (20,21), the trends are not clear. For example, the previous reviews indicated that age may have a negative impact on semen volume, sperm motility and morphology, but data regarding age and sperm concentration are more controversial (20,21). Our study presented the negative effect of male age on semen volume and total sperm count, but not on sperm motility, morphology and concentration.…”

“…47 Interestingly, the effects of APA were not dependent on female age, suggesting that males alone contributed to this effect. 3,47 Other studies demonstrated similar effects. For example, a prospective study from Europe examining 782 couples (women aged 18-40) who achieved pregnancy by intercourse alone, reported that when women reached their late thirties, male age became a significant factor in achieving pregnancy.…”

“…As improvements in reproductive technologies have pushed the frontiers of reproductive medicine, media reports of elderly men fathering children 1 have raised awareness and garnered acceptance of advanced paternal age (APA) in modern times. [1][2][3][4] Societal pressures are partly to blame for the trend of couples delaying childbearing well into their mid-to late-thirties. Careers and educational aspirations, along with an increased life expectancy and the nearly ubiquitous use of contraception, have decreased accidental birth rates and increased parental age at first childbirth.…”

“…Approximately 15% of couples worldwide experience infertility, and as many as half of the cases are due to male specific pathologies [54]. The specific causes of male infertility are numerous, and include genetic factors in germ or somatic cells of the testis, age, medical treatment, endocrine system disruption, post-testicular disorders and environmental factors [55][56][57][58]. Many cases of male infertility are idiopathic (unknown cause) and are the impetus for further investigation into molecular mechanisms that maintain healthy steady state spermatogenesis.…”
