Here are some of the articles in my file base that I found interesting and applicable to your queries.The first one on Rotties is the one I believe you are speaking of.

Rottweiler study links ovaries with exceptional longevity

Early Spay/Neuter: An Overview

Long-term risks and benefits

of early-age gonadectomy in dogs

A population study of neutering status as a risk factor for canine prostate cancer

The following was taken out of the text of a Rutgers University Masters Thesis under the doctrine of Animal Sciences, by Ms L J Sanborn:

On the positive side, neutering male dogs

eliminates the small risk (probably <1%) of dying from testicular cancer

reduces the risk of non-cancerous prostate disorders

reduces the risk of perianal fistulas

may possibly reduce the risk of diabetes (data inconclusive)

On the negative side, neutering male dogs

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.

increases the risk of cardiac hemangiosarcoma by a factor of 1.6

triples the risk of hypothyroidism

increases the risk of progressive geriatric cognitive impairment

triples the risk of obesity, a common health problem in dogs with many associated health problems

quadruples the small risk (<0.6%) of prostate cancer

doubles the small risk (<1%) of urinary tract cancers•

increases the risk of orthopedic disorders

increases the risk of adverse reactions to vaccinations

On the positive side, spaying female dogs
if done before 2.5 years of age, greatly reduces the risk of mammary tumors, the most common
malignant tumors in female dogs
nearly eliminates the risk of pyometra, which otherwise would affect about 23% of intact female
dogs; pyometra kills about 1% of intact female dogs
reduces the risk of perianal fistulas

removes the very small risk (0.5%) from uterine, cervical, and ovarian tumors

On the negative side, spaying female dogs

if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a
common cancer in larger breeds with a poor prognosis
increases the risk of splenic hemangiosarcoma by a factor of 2.2 and cardiac hemangiosarcoma by
a factor of >5; this is a common cancer and major cause of death in some breeds
triples the risk of hypothyroidism

increases the risk of obesity by a factor of 1.6-2, a common health problem in dogs with many

associated health problems

causes urinary “spay incontinence” in 4-20% of female dogs
increases the risk of persistent or recurring urinary tract infections by a factor of 3-4
increases the risk of recessed vulva, vaginal dermatitis, and vaginitis, especially for
female dogs
spayed before puberty
doubles the small risk (<1%) of urinary tract tumors
increases the risk of orthopedic disorders

increases the risk of adverse reactions to vaccinations

Hope this gives you some additional research.
