A guide to proper semen collection and shipment.

The testis can be affected with several types of tumors.

Clinical reproductive case studies.

Bitches with the history of subfertility or infertility should be examined for pregnancy at 25 days following the last breeding using ultrasonographic examination or palpation depending upon the animal and the examiner.

A technician's guide to examining female breeding soundness.

The history is too important and too frequently ignored!

The time spent on history taking is the most important time devoted to a case.

A guide to examining female breeding soundness.

Bitches generally attain puberty two to three months after reaching adult body size.

The testicles in the stud dog are housed in the scrotum, a skin sac located between the thighs.

The testis can be affected with several types of tumors.

Indications for Karyotyping include possible testicular hypoplasia/aplasia, abnormal external phenotype (e.g. small penis, ambiguous genitalia), and suspected congenital lesions associated with infertility.

The infertile animal is commonly presented with historic evidence of an unsuccessful breeding.

The male is prepared for semen collection by placing him in a quiet area with minimal disturbances.

The testicles in the stud dog are housed in the scrotum, a skin sac located between the thighs.

The examination should begin with a complete history in regard to the previous uses and the previous breeding experiences and outcomes if available.

Four case studies in reproduction.

Bitches generally attain puberty two to three months after reaching adult body size.

Bitches with the history of subfertility or infertility should be examined for pregnancy at 25 days following the last breeding using ultrasonographic examination or palpation depending upon the animal and the examiner.
