Sperm addict

Two young German sluts have gone to a club for group sex with lots of men. They are addicted to sperm and enjoy a lot with all these cocks at their disposal.

Nevertheless these age-related declines are Lexi belle twitter modest in degree, and the extent to which they would increase delayed conception and treatment for male infertility remains uncertain. Google Scholar. This reduced Dubbeldildo output with ageing is consistent with the impairment of spermatogenesis identified from detailed but small quantitative post mortem studies Cumathon sperm production Foot worship reviewed in Johnson,as well as a larger study of testis size Handelsman My sisters ass hole Staraj, of men dying suddenly.

Repeated attempts to categorically distinguish such groups have generally been unsuccessful MacLeod and Gold, ; Meistrich and Brown, ; Guzick et al.

One approach is to compare the findings with a conventional benchmark, for which the WHO Semen Manual reference criteria would serve well.

By these criteria, the overall reduction in semen quality among the older men was modest and still largely conducive to fertility.

Nevertheless, on average, men of this age may take longer to produce a pregnancy, and a higher proportion may warrant treatment for male infertility by conventional standards.

We conclude that in this convenience sample of older non-infertile men, sperm density is not reduced compared with younger men, but that reduced semen volume masks a decline in total sperm output.

In addition, sperm morphology and vitality decline with age. Nevertheless these age-related declines are only modest in degree, and the extent to which they would increase delayed conception and treatment for male infertility remains uncertain.

Considering the increasingly later age of marriage, the increasing frequency of remarriage and longer life expectancy of men who are theoretically capable of achieving paternity lifelong, the paucity of studies in this area is striking, and more detailed studies of non-infertile older men are desirable.

Parental smoking can increase the risk of childhood wheezing, bronchitis and asthma in children, although the connection between asthma was highest in children whose mothers smoked during pregnancy, according to an Austrian study analysis reported in the issue of "Tobacco Control.

Animal studies have shown more effects from paternal addiction than human studies. It may be that more of a connection exists than has currently been uncovered.

The present study's findings are also consistent with the conclusions of a systematic literature review of ageing effects on semen analysis Kidd et al.

Following evaluation of 28 studies of semen analysis, it was concluded that ageing is associated with a decline in semen volume and sperm morphology, but not sperm density.

However, that review did not evaluate total sperm output, a parameter less affected by abstinence interval, a variable in turn not well controlled in most studies.

Furthermore, most studies reviewed comprised men attending fertility clinics, with very few over 50 years old.

In that context the present study extends these findings to a larger group of older, non-infertile men. The present opportunistic study suffers from the significant limitation of non-representative sampling that is virtually unavoidable in studies requiring semen analysis Cohn et al.

Similar issues essentially invalidate claims regarding historical changes in sperm output where non-representative samples were extrapolated to their epoch or geographical location Handelsman, It would be equally mistaken to extrapolate the present data to older men without strong caveats and independent replication.

Nevertheless, by sacrificing sperm motility assessment, using this convenience sample we were still able to analyse ejaculate volume, sperm density, output, vitality and morphology in older men and compare with younger men recruited and examined in the same clinic and laboratory.

However, the requirement for a semen sample will have limited the participation in the present study to not only potent men, but also to those with different attitudes, the impact or correlates of which on preservation of testicular function with ageing remains unknown.

An additional caveat on this sample is that the older men were biased by selection for requiring a prostate biopsy to evaluate possible prostate cancer.

Prostate disease can theoretically obstruct the excurrent ductular system or have more general systemic effects on spermatogenesis.

However, men with and without biopsy-proven prostate cancer did not differ with regard to semen variables. The general good health of the participants in this study together with the minimal extent and low grade of the biopsy-proven cancers make it unlikely that systemic effects of the cancer would be sufficient to influence sperm production.

Although it is well established that chronic, even asymptomatic, disease may accelerate the age-dependent decline of blood testosterone Gray et al.

These considerations suggest that sperm production and function in the older men was minimally or not influenced by their selection for prostate biopsy.

Evaluating the potential impact of ageing changes of this magnitude on fertility is speculative. It has long been known that conventional semen parameters overlap between men who are defined as fertile, infertile and the majority who, at any time, have undefined fertility.

Repeated attempts to categorically distinguish such groups have generally been unsuccessful MacLeod and Gold, ; Meistrich and Brown, ; Guzick et al.
