约克夏狗公狗节育的坏处

节育对于公狗的坏处：
On the negative side, neutering male dogs
1）如果过早节育（早于一岁前），极大地增加了患骨癌的几率；骨癌对于中/大型犬来说是非常常见的。
? if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a
common cancer in medium/large and larger breeds with a poor prognosis.
2）增加了心血管瘤的发病率（增加的几率为参数1.6，我的理解是1.6倍于不节育的公狗，不知道对不对)（只能是大概意思，又碰到了不完全懂的专业术语）
? increases the risk of cardiac hemangiosarcoma by a factor of 1.6
3）相比较于未节育的公狗，甲状腺机能减退的几率增大为其三倍
? triples the risk of hypothyroidism
4）渐进的老年认知障碍（是指老年性痴呆么，每个词都懂，连起来反而不懂了。）几率增加
? increases the risk of progressive geriatric cognitive impairment
5）肥胖的几率比未节育的狗狗增大三倍
? triples the risk of obesity, a common health problem in dogs with many associated health problems
6）前列腺癌的发病率增大为四倍（不过依旧很小，小于0.6%）
? quadruples the small risk (<0.6%) of prostate cancer
7）尿道癌的发病率增大为两倍（小于1%）
? doubles the small risk (<1%) of urinary tract cancers
8）骨骼系统（包括骨头，关节，韧带和肌肉）疾病发病率增大
? increases the risk of orthopedic disorders
9）接种疫苗时的不良反应几率增加
? increases the risk of adverse reactions to vaccinations
对于公狗的节育考虑，不能忽视节育引起的骨肉瘤，血管肉瘤，甲状腺机能减退和其它相对较少发生的病症的发病几率增高的问题。
One cannot ignore the findings of increased risk from osteosarcoma, hemangiosarcoma, hypothyroidism, and other less frequently occurring diseases associated with neutering male dogs.
