New approaches to superovulation in the cow
Reproduction, Fertility and Development, 2009 There is continuing need to simplify bovine superovulation protocols without compromising embryo production. The control of follicular wave emergence and ovulation has facilitated donor management, but the most commonly used treatment, oestradiol, cannot be used in many parts of the world and mechanical removal of the dominant follicle is difficult to ...

Administration of Gonadotropins for Superovulation in Mice
Cold Spring Harbor Protocols, 2018 For experiments that require large numbers of preimplantation mouse embryos, such as microinjection of zygotes, gonadotropins are administered to females before mating to increase the number of oocytes that are ovulated (i.e., to induce superovulation).

Reproductive Toxicology, 2009 Some steps of the assisted reproduction techniques, such as superovulation, may interfere with imprinting reprogramming. In the present study, superovulation was induced in the mouse and its possible effects on the differentially methylated domains of 2 ...

Animal Reproduction Science, 2007
Embryo recovery from single ovulating mares is approximately 50 per cent per estrous cycle. Superovulation could be used to increase embryo recovery and provide extra embryos for embryo freezing. This review addresses some historical approaches to superovulation, as well as examines factors that affect the response of mares to equine FSH. eCG, GnRH and

Fertility and Sterility, 1992 Objective: To determine the efficacy of superovulation with buserelin acetate, human menopausal gonadotropins (hMG), and human chorionic gonadotropin (hCG) in the treatment of infertility associated with minimal or mild endometriosis.

Veterinary Clinics of North America: Equine Practice, 1996
Development of a superovulation technique that is successful, safe, and commercially available would revolutionize the equine breeding industry. However, the reality is that ovulation rates for mares following existing superovulatory treatment are much lower than for cattle. This dichotomy has been attributed to the relatively limited area available in

Veterinary Clinics of North America: Equine Practice, 2006
Recently, a commercial product has been made available (equine follicle-stimulating hormone [eFSH]) for superovulating mares. This has provided the practitioner with a hormonal product that is readily available for enhancing multiple ovulations. Additional benefits of stimulating multiple follicles include an increased number of follicles available for

Superovulation and oocyte recovery in the ewe
Theriogenology, 1988Thirty-eight adult ewes were superovulated following a 12 d progestagen treatment in association with either 135 mg crude horse anterior pituitary extract (HAP) or 30 mg soluble HAP with or without 1000 IU human chorionic gonadotrophin (hCG). Soluble HAP in combination with hCG significantly (P < 0.01) increased the ovulation rate as compared to HAP ...

Premature ovulations in superovulated cattle
Theriogenology, 1987The incidence and consequences of premature ovulations in superovulated cattle were studied. These ovulations, presumably induced by the luteinizing hormone content of the gonadotrophin preparation used, were found in 17 of 133 (13%) stimulated cows and heifers used as oocyte donors.
