superovulation

su·per·ov·u·la·tion

(sū'pĕr-ov'yū-lā'shŭn),

Ovulation of a super normal number of ova; usually the result of the administration of exogenous gonadotropins.

superovulation

/su·per·ov·u·la·tion/ (ov″u-la´shun) extraordinary acceleration of ovulation, producing a greater than normal number of oocytes.

superovulation

Reproduction medicine Hyperstimulation of the ovaries with gonadotropins to drive development of dominant follicles; SO is commonly used in couples with unexplained or male-factor infertility. See Artificial reproductive technology.

superovulation

The production of more than one or two ova at one time. Superovulation is common when drugs are used to stimulate ovulation in the treatment of infertility.

superovulation

production of more than one ovum at ovulation.

1. Planned production of a number of ova from the one cow at the same ovulation period is an essential part of the technique of bovine embryo transfer. Can be effected with a single injection of PMSG or for better results, with FSH and LH in a 5:1 ratio, twice daily for 5 days. Called also multiple ovulation.

2. Can occur accidentally when cows are treated with large doses of FSH as a treatment for no visible estrus.
