Assisted reproductive techniques for hybridization of camelids

Reproduction, Fertility and Development, 2001
The camelid family comprises the Old World camelids (or dromedary and Bactrian camels) and the New World camelids (namely the llamas, alpacas, guanacos and vicunas). Although the species within each group can hybridize among themselves to produce fertile offspring, it is only recently that a hybrid between New and Old World camelids has been reported.

Assisted reproduction techniques in the horse

Reproduction, Fertility and Development, 2013
This paper reviews current equine assisted reproduction techniques. Embryo transfer is the most common equine ART, but is still limited by the inability to superovulate mares effectively. Immature oocytes may be recovered by transvaginal ultrasound-guided aspiration of immature follicles, or from ovaries postmortem, and can be effectively matured in ...

Assisted Reproductive Techniques in the Horse

Clinical Techniques in Equine Practice, 2005
Embryo transfer is commonly performed in equine practice, both to increase production from a given mare and to obtain offspring from mares that suffer early embryo loss. Oocyte transfer is a more specialized technique that is used clinically to obtain offspring from mares that cannot provide an embryo for embryo transfer. Gamete intrafallopian transfer

A critical appraisal of assisted reproduction techniques

Human Reproduction, 1993
Several treatments for infertility have been promoted with only little supporting objective data demonstrating their therapeutic value. The choice of an assisted reproductive technique depends on a balance between numerous factors. Seldom is the choice absolute as in patients with tubal block.

Oocyte Maturation in Assisted Reproductive Techniques

Annals of the New York Academy of Sciences, 2006
Abstract:  Human oocyte maturation is a long process during which nuclear maturation occurs resulting in germinal vesicle breakdown (transition from prophase I to metaphase II) and extrusion of the first polar body. During oocyte maturation, in parallel with nuclear maturation, a number of events take place in the oocyte cytoplasm that assist ...

Oocyte quality in assisted reproduction techniques

Minerva Endocrinology, 2022
The metaphase II (MII) oocyte is the mature female gamete, produced from a complex maturation process called oogenesis that starts in the first weeks of embryogenesis in the female embryo tract, continues during puberty, and is completed at fertilization with the spermatozoon. Oogenesis is closely related to folliculogenesis.

Dietary Patterns and The Outcomes of Assisted Reproductive Techniques in Women with Primary Infertility: A Prospective Cohort Study

International Journal of Fertility and Sterility, 2018
Background Infertility is one of the most common challenges that women in reproductive age would encounter today. The maternal nutritional status could be a determinant of oocyte quality and embryonic growth.

Is there a place for immunomodulation in assisted reproduction techniques?

Journal of Reproductive Immunology, 2004
We briefly review the history of the concepts of the materno foetal relationship, and the (various) rationales which have been used to justify lymphocyte alloimmunisation (LA) as a treatment for recurrent spontaneous abortion of putative immune origins.

Oxidative stress in an assisted reproductive techniques setting [PDF]

Fertility and Sterility, 2006
The manipulation of gametes and embryos in an in vitro environment when performing assisted reproductive techniques (ART) carries the risk of exposure of these cells to supraphysiological levels of reactive oxygen species (ROS). The main objective of this review is to provide ART personnel with all the necessary information regarding the development of
