What triggers ovulation in mice?
A rapid increase in plasma estradiol concentration during proestrus generates a positive feedback mechanism that triggers a surge in GnRH secretion (Miller and Takahashi 2014). In turn, GnRH stimulates the production of LH from the anterior pituitary gland, which then triggers ovulation (Miller and Takahashi 2014) .

How can I induce ovulation immediately?
Ovulation is induced using one of two main drug regimens: Clomiphene or Clomid tablets (alternatives are Tamoxifen and Letrozole tablets) increase the production of follicle stimulating hormone (FSH) by the pituitary gland, thereby stimulating follicles and hence egg growth.
How do you induce ovulation naturally?

What animals have induced ovulation?
Species in which the females are induced ovulators include cats, rabbits, ferrets, and camels. In 1985, Chen et al., used Bactrian camels to investigate the factor(s) that induce ovulation during breeding season. They monitored the camel ovaries for ovulation by rectal palpation following insemination of semen samples.

Can female get pregnant without a male?

How can I stimulate ovulation?
