Was jetzt aber nur eines beweist: Dass die Studien seiner Meinung nach voreingenommen sind.
Seine Aussage sagt also nur das, und nicht, dass sich Kastra nicht positiv auf die Entwicklung von Gesäugekrebs auswirkt.
Und doch, es gab über 11.000 Artikel die die sich zusammengesucht haben, aber schlussendlich blieben eben nur 13 übrig, weil einige nicht in Englisch waren, oder nicht gefunden werden konnten, etc. (steht in so einer langen Version).
und guck mal hier: derselbe Typ schreibt auch, dass es keine Beweise gibt, dass Kastra sich auf Inkontinenz auswirkt. Obwohl da eben zig Erfahrungsbereichte drüber berichten. Aus praktisch denselben Gründen, da "biased"
Abstract
An increased risk of urinary incontinence in bitches has often been associated with previous ovariohysterectomy but remains controversial. The objective of this study was to evaluate the strength of evidence for an association between neutering or age at neutering and urinary incontinence in bitches and to estimate the magnitude of any effect found. A systematic review of peer-reviewed original English analytic journal articles was conducted, based on Cochrane guidelines (Higgins and Green 2009) Of 1,853 records screened, seven studies were identified that examined the effect of neutering or age at neutering on the risk of urinary incontinence but four were judged to be at high risk of bias. Of the remaining three studies, which were at moderate risk of bias, there was some weak evidence that neutering, particularly before the age of three months, increases the risk of urinary incontinence. However, overall the evidence is not consistent nor strong enough to make firm recommendations on the effect of neutering or age at neutering on the risk of urinary incontinence.
Conclusion
The evidence for a causal relationship between neutering and
urinary incontinence is weak, although there is some evidence
of an association. There is some weak evidence that the risk of
urinary incontinence decreases as the age at spay increases, up to
12 months of age, after which there is no evidence of an effect
of age at spay. There was no direct evidence found in this review
that the occurrence or absence of oestrous before neutering plays
a role in the aetiology of urinary incontinence. This information
should be balanced with other available information on the risks
and benefits of neutering.
Further research on the association between urinary incontinence
and neutering should focus on recording age, breed and
tail docking as potential confounders. Occurrence of oestrous
before neutering should be recorded and studies should ideally
include dogs neutered at a wide range of ages. In addition, a reliable
definition of urinary incontinence should be used, and it
should be shown that dogs considered

Weiss ja nicht. Also da geb ich persönlich dann schlussendlich doch mehr auf die Meinung einer Tierärztin, die eben gerade in zwei so unterschiedlichen Ländern gearbeitet hat und dann den direkten Vergleich hat, tagtäglich auf ihrem Praxistisch, anstelle von jemand, der irgendwie nur Studien durchliest und die dann bewertet. Was ja nicht mal was direkt mit der Materie zu tun hat.
