“…Some suggested no association [Oldereid et al 1992;Ramlau-Hansen 2008], whereas others found reduced sperm concentration, total sperm count, and motility [Jensen et al 2010;Sobreiro et al 2005;Vine 1996]. In the present study, coffee consumption increased the percentage of motile sperm cells and the percentage of sperm head and neck abnormalities.…”

(2014) Lifestyle and semen quality: role of modifiable risk factors, Systems Biology in Reproductive Medicine, 60:1, 43-51, DOI: 10.3109/19396368.2013.840687 To link to this article: https://doi.org/10. 3109/19396368.2013 AbstractThe relationship between exposure to lifestyle factors and adverse effects on human reproductive health is debated in the scientific literature and these controversies have increased public and regulatory attention. The aim of the study was to examine the association between modifiable lifestyle factors and main semen parameters, sperm morphology, and sperm chromatin structure. The study population consisted of 344 men who were attending an infertility clinic for diagnostic purposes with normal semen concentration of 20-300 M/ml or with slight oligozoospermia (semen total concentration of 15-20 M/ml) [WHO 1999]. Participants were interviewed and provided semen samples. The interview included questions about demographics, socio-economic status, medical history, lifestyle factors (consumption of alcohol, tobacco, coffee intake, cell phone and sauna usage), and physical activity. The results of the study suggest that lifestyle factors may affect semen quality. A negative association was found between increased body mass index (

“…Some studies have reported that caffeine may be associated with high levels of testosterone and sex hormone-binding globulin and low levels of estrogen, but no effect on semen quality has been found. 24,25 Swan et al 26 claimed that a high cola (>14 0.5-litre bottles/week) and/or caffeine (>800 mg/day) intake was associated with a reduced sperm concentration and a lower total sperm count, although this was only significant for cola intake. Jensen et al 23 showed that caffeine intake of <800 mg per day (about 7 cups of coffee) was not associated with reduced semen quality.…”

BackgroundNumerous studies have shown the associations between different dietary patterns and semen quality in a male population. There is no evidence on the relationship between dietary intake and markers of male fertility potential. The aim of this study was to investigate the relationship between dietary nutrients intake and semen quality parameters among healthy men from Lower Silesia (a region of Poland).

“…Conflicting results still seem to characterize the association between male caffeine consumption in adult life and semen quality, whereas the association between prenatal coffee consumption and semen quality and levels of reproductive hormones seems to be responsible for a small to moderate effect on semen volume and the levels of reproductive hormones (Ramlau-Hansen et al 2008) .…”

Reproduction is the process by which organisms create descendants. In human reproduction, two kinds of sex cells, or gametes, are involved. Sperm, the male gamete, and egg egg , or ovum ovum Vedi egg , the female gamete, must meet in the female reproductive system to create a new individual and both the female and the male reproductive systems are essential to the occurrence of reproduction. Scientific reports dealing with the effects of methylxanthines on reproduction are mostly centred on the use of these compounds as phosphodiesterase inhibitors that, by maintaining high intracellular levels of cyclic AMP (cAMP) cyclic AMP , will affect the gametes differently. High cAMP levels will sustain sperm sperm maturation while they hold the oocytes in mitotic arrest. Caffeine caffeine , being the methylxanthine most widely consumed by every segment of the population, has been the subject of greatest interest among health professionals and researchers. Conflicting results still seem to characterize the association between male/female caffeine caffeine consumption in adult life and semen quality/fertility fertility , although moderate daily caffeine consumption of levels up to 400-450 mg/day (5.7-6.4 mg/kg/day in a 70-kg adult) do not seem to be associated with adverse effects, i.e. general toxicity, effects on bone status and calcium balance, cardiovascular effects, behavioural changes, increased incidence of cancer, or effects on male fertility. A clear stimulation of egg-laying by the coffee leaf pest Leucoptera coffeella was recently reported, providing support for the hypothesis that caffeine, in a dose-dependent way, in insects stimulates egg-laying, thus leading to the death of coffee trees.
