Despre sterilizareAbout spaying and neutering

Conform celor mai recente si ample studii medicale:

Tumorile mamare sunt de 3 ori mai frecvente la catea decat la femeie. Dintre tumorile mamare, sunt maligne 53% la catea si 90% la pisica.
Fata de catelele nesterilizate, catelele sterilizate inainte de primele calduri (care apar la varsta de 7-9 luni) au un risc de cancer mamar redus de 200 de ori, iar catelele sterilizate dupa primele calduri au un risc de cancer mamar redus de 12.5 ori.

In plus, sterilizarea prin ovariohisterectomie (eliminarea ovarelor si a uterului) elimina complet riscul de aparitie a cancerului ovarian sau a piometrului (puroi in uter). Piometrul este o boala frecventa la femelele nesterilizate, este dificil de diagnosticat in stadiile initiale si prezinta risc letal in stadiu avansat.

In concluzie, cel mai bine pentru sanatatea unei femele, catea sau pisica, este sa fie sterilizata la o varsta intre 3 si 6 luni (dupa imunizare si inainte de primele calduri).

Studiile recente indica o varsta recomadata similara si pentru sterilizarea masculilor.

Sterilizarea timpurie nu are efecte negative asupra sanatatii. Efectele secundare ale sterilizarii pre-puberale sunt minore: pe de o parte organele genitale externe isi reduc marimea, iar pe de alta parte cresterea oaselor lungi se prelungeste uneori cateva luni.

Exista si alte avantaje importante ale sterilizarii:

la motanii castrati, reducerea bulbului penian face ca riscul aparitiei blocajului uretral sa fie mai mic decat la cei ne-castrati
masculii de caine castrati sunt feriti de bolile prostatei, care apar mai ales la varsta inaintata
masculii castrati sunt feriti de riscul aparitiei cancerului testicular
exista o corelatie demonstrata statistic intre starea de animal sterilizat si un nivel redus al agresivitatii. Este adevarat ca sterilizarea in sine nu rezolva automat si sigur probleme de comportament ale unui animal: acestea se trateaza prin efort de dresaj si educare. Dar este cert, verificat statistic, ca incidentele cu oameni muscati de caini implica in 6 cazuri din 10 caini nesterilizati. (Vezi, de pilda, http://www.dogbitelaw.com/PAGES/statistics.html)
statistic, durata de viata creste semnificativ la animalele castrate.

According to the latest and the most extensive medical studies:

-Mammary tumors are 3 times more common at a female dog, than at a woman. Of those tumors, 53% are malignant at dogs, and 90% are malignant at cats.

-Female dogs which are sterilized before they are able to breed, have a 200 times lower risk to have breast cancer(7-9 months) ,and the ones which are sterilized after the first time they are able to breed have a 12,5 times lower risk than unneutered female dogs.

Moreover,the ovariohysterectomy (the elimination of the ovaries and uterus) completely eliminates the risk of ovarian cancer or of pyometra (pus in the uterus). Pyometra is a very common disease common at unsterilized dog females, it’s difficult to diagnose in its early stages and fatal at the final stage.

In conclusion, it’s best for the health of any female(cat or dog) to be sterilized between 3 and 6 months(after immunization and before the first heat).

Recent studies recommend sterilizing males between same age.

Early sterilization doesn’t have adverse health effects .Side effects of sterilizing prepubescent are minor: external genital organs reduce their size; growth of long bones sometimes lasts several months.

Important advantages of sterilization are:

-at neutered tomcats, reducing the penile bulb makes the risk of urethral blockage to be lower than at non-castrated tomcats.

-neutered male dogs aren’t likely to have prostate disease, occurring especially in old age.

-neutered males are protected from the risk of testicular cancer.

-there is a statistically proven correlation between being sterilized animals and a low level of aggression.

It is true that sterilization itself does not automatically solve certain problems of an animal behavior: they are treated with training and education effort. But it is certainly statistically verified that incidents of dogs biting people involve in 6 cases out of 10 unsterilized dogs(See, for example, http://www.dogbitelaw.com/PAGES/statistics.html)

Statistically, castrated animals live longer than unsterilized ones.
