But, there are arguably many reasons to completely avoid shaving your balls altogether. We will discuss just a few of those here. Of all the external parts on the male anatomy that naturally grow hair, the testicles are the area that is perhaps the least friendly to getting scraped with a razor.
The results of the joint study by the University of Western Australia and the University of Zurich about the relationship between the size of sexual ornaments and testes in primates were misinterpreted and wrongly assumed to be about the difference between individual humans. We want to make clear that this was an editorial error and apologize profusely to our readers for this. At VT we take false news very seriously and want to assure all our readers that our articles are fact-checked strenuously before publishing.
Most men who have lost one testicle due to cancer do not need testosterone replacement. When one testicle has been surgically removed the other one produces extra hormones to compensate for what is lost. However, there are rare situations when men are advised to have male hormone replacement therapy HRT see 'Hormone treatment'.
Testes of seasonally breeding species experience a severe functional regression before the non-breeding period, which implies a substantial mass reduction due to massive germ-cell depletion. Two alternative mechanisms of seasonal germ-cell depletion have been described in mammals, apoptosis and desquamation sloughingbut their prevalence has not been determined yet due to reduced number of species studied. We performed a morphological, hormonal, and molecular study of the mechanism of seasonal testicular regression in males of the Egyptian long eared-hedgehog Hemiechinus auritus. Our results show that live, non-apoptotic, germ cells are massively depleted by desquamation during the testis regression process.

Electronic address: sdj uowmail. The phenotype-linked fertility hypothesis proposes that secondary sexual characters SSCs advertise a male's fertility to prospective mates. However, findings from empirical studies attempting to test this hypothesis are often ambivalent or even contradictory, and few studies have simultaneously evaluated how both morphological and behavioural SSCs relate to ejaculate characteristics. Males of the small hairy maggot blowfly, Chrysomya varipes, possess conspicuous foreleg ornaments and display highly stereotyped courtship behaviour.
