There are obstacles to the success of equine embryo transfer programs, concomitantly there has been an increase in the popularity of the technique. One of the most urgent issues to overcome is related to the recipient mare availability and the donor-recipient synchrony. Usually, the donor mares have a higher body condition score and are fed a higher quality diet than recipient mares during the non-breeding season. Therefore, the donor mares start cycling earlier than recipient mares, which makes embryo transfer challenging. Several studies have been carried on finding hormonal protocols that mimic the natural oestrous cycle to allow the use of noncycling recipient mares for embryo transfer programs. Many protocols can be found in the literature, using different doses and intervals. Among the main difference is the use of progestogens, which can be used alone or in combination with oestradiol. The aim of this review was to analyse results that could help solve the lack of recipient mares and improve the results of the embryo transfer technique.

It the past few years, there has been a growing interest about the eventual side effects concerning gonadectomy in dogs and bitches. Most publications focus on health problems : obesity, cancers, osteoarticular or ligamentary disorders, longevity. Fewer articles have studied the effect of gonadectomy on behavior. Castration often reduces unwanted behaviors in castrated male dogs, but it may increase some types of agressivity towards other dogs or even humans, depending on the age at neutering.

In recent years, there has been a great interest of purebred cat breeders in the possibilities and benefits of implementing of consistent veterinary care on reproduction. This includes tools available in the field of Assisted Reproductive Technologies (ART). As in dogs before, there is a tendency to reduce the reproductive potential of purebred cats, which is partly due to the nature of the selection of animals for reproduction on the basis of phenotypic features, omitting the control of their fertility. It is worthy to note hazardous specificity of this selection where inbreeding is commonly used. If all this is imposed on the frequent occurrence of infectious diseases in a domestic cat, then the population of purebred cats appears as a group of animals, which is a kind of challenge for a specialist of reproduction. This is a paradoxical phenomenon, because regarding non-purebred cats, the main challenge for the veterinary community is to limit their population. Some of the most important barriers to the implementation of advanced control of reproduction of purebred cats over the years have been: 1) difficulties with sperm collection, 2) technically troublesome artificial insemination, 3) numerous and difficult to recognize and treat forms of fertility disorders. In recent years, progress has been observed within each of these areas. It is possible to implement into practice extremely valuable tools that are helpful in monitoring the reproductive status of these animals. The breakthrough was the development of effective methods of semen collection, its evaluation and preservation and the development of increasingly effective methods of artificial insemination. Therefore, there is a real prospect of organizing cat reproduction centers operating within veterinary facilities dealing with small animals. The time is coming to carry out veterinary care for cat reproduction at such an advanced level as it has been developed in recent decades for dogs. Development in this area is facilitated by progress in research on the field of the use of ART in programs of rescue of endangered feline species where domestic cat is treated as model animal.
