Pregnancy in the domestic cat after artificial insemination with previously frozen spermatozoa

Artificial insemination with canine spermatozoa frozen in a skim milk/glucose-based extender.

Due to the recent outbreak of avian influenza, transportation of frozen canine semen with egg yolk has been sharply restricted. Thus, there is urgent need to develop a novel egg yolk-free extender for freezing canine spermatozoa. In the present study, the effect of using skim milk/glucose (SG)-based extender without egg yolk on the motility and fertilizing capacity of canine spermatozoa frozen-...

Fertility Results After Artificial Insemination with Bull Semen Frozen with Low Density Lipoprotein Extender

Semen Collection and Assessment, and Artificial Insemination in the Cat

Introduction Both semen collection and artificial insemination (AI) in cats was first described more than 30 years ago [1] but the procedures are still not routine because very few veterinary clinics are offering these services. While the more advanced biotechnology techniques such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI) and cloning have been successfully perfor...

Effects of acrosomal conditions of frozen-thawed spermatozoa on the results of artificial insemination in Japanese Black cattle

The purposes of this study were to examine the relationship between male artificial insemination (AI) fertility and sperm acrosomal conditions assessed by new and conventional staining techniques and to identify possible reproductive dysfunctions causing low conception rates in AI using frozen-thawed spermatozoa with poor acrosomal conditions in Japanese Black bulls. We investigated individual ...
