Consequences of Superovulation and ART Procedures

Seminars in Reproductive Medicine, 2012
Superovulation procedures and assisted reproductive technologies (ART) have provided the means for significant improvement in infertility care. Although generally safe, these procedures are associated with complications that, albeit rare, can have significant morbidity.

Superovulation in mares

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

Superovulation

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

Superovulation in Mares

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

Premature ovulations in superovulated cattle

Theriogenology, 1987
The 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.

Superovulation and oocyte recovery in the ewe

Theriogenology, 1988
Thirty-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 ...

Cyclophosphamide: Induction of Superovulation in Rats

Nature, 1973
THE number of ova released at ovulation in rats varies within a narrow limit, usually between 10 and 15. Factors which maintain this relative constancy are not known. Several agents capable of inhibiting ovulation are known1,2, but apart from gonadotrophin injections there appears to be no way to increase the normal ovulation rate7. An agent capable of
