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 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

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 ...

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.

Video recording and reproduction techniques

Electronics and Power, 1972
Only a decade ago videotape machines cost tens of thousands of pounds and film-recording equipment was only slightly cheaper. Holography was an unknown word in television circles and it seemed impossible to record 625-line colour signals on a disc.

Assisted Reproduction: Techniques and Participants

2003
Oocytes of rabbits and mice, successfully cultured in vitro in the first half of the twentieth century, laid the foundation for assisted reproductive techniques decades later. In vitro fertilization (IVF) studies in rabbits resulted in the first birth of a normal offspring in 1959.

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.

Monitoring reproduction using immunological techniques

Animal Reproduction Science, 1992
Abstract Immunological techniques have been developed to monitor reproduction under practical conditions. Of these, techniques for confirmation of oestrus and diagnosis of pregnancy are of major importance. The milk progesterone test for dairy cattle and the oestrone sulphate test for pigs are considered and a recently developed novel cow side milk ...
