Low-dosage clomiphene reduces premature ovulation rates and increases transfer rates in natural-cycle IVF [PDF]
Reproductive BioMedicine Online, 2014 Natural-cycle IVF has been suggested as an alternative IVF treatment. However, efficacy is limited due to high premature ovulation rates, resulting in low transfer rates. This study investigates whether low dosages of clomiphene citrate reduce premature ovulation rate and increase transfer rate.

Multiple cAMP Phosphodiesterases Act Together to Prevent Premature Oocyte Meiosis and Ovulation [PDF]
Endocrinology, 2018 Luteinizing hormone (LH) acts on the granulosa cells that surround the oocyte in mammalian preovulatory follicles to cause meiotic resumption and ovulation. Both of these responses are mediated primarily by an increase in cyclic adenosine monophosphate (cAMP) in the granulosa cells, and the activity of cAMP phosphodiesterases (PDEs), including PDE4 ...

Variable Response to Hormonal Induction of Multiple Ovulation in Quail
The Journal of Poultry Science, 2003 Studies were conducted to induce multiple ovulation in Japanese quail. Laying quail were injected with 20I.U./quail of PMSG once a day for 5 successive days followed by a single treatment with 50μg/quail of oLH about 24hr after the last PMSG injection.

Inhibition of Premature Ovulation By Prolactin in the Hen
Poultry Science, 1971 Abstract PROLACTIN is a pituitary hormone which is known to induce broodiness in some breeds of chickens (Riddle et al., 193S; Saeki and Tanabe, 1955). Although the site of action of prolactin in causing broodiness has not been clearly demonstrated, successive injections of this hormone into the chicken were found to cause a decrease in ovarian and ...

Spontaneous pregnancy in a patient with premature ovarian insufficiency after a failed attempt of ovulation induction [PDF]
International Journal of Reproduction, Contraception, Obstetrics and Gynecology, 2021 Premature ovarian insufficiency (POI) is defined as intermittent or permanent gonadal insufficiency before age of 40 years. POI causes female infertility hence pregnancies are uncommon but not impossible. Ovarian failure is not permanent, unlike menopause. There could be intermittent ovulation and spontaneous pregnancy.

Occurrence of Premature Ovulation in the Domestic Fowl Following Administration of Progesterone.
Experimental Biology and Medicine, 1943 SummaryThe administration of crystal-line progesterone to the common domestic hen is highly effective, under stated conditions, in causing premature ovulation of normally developing ovarian follicles. Results differ with route of injection, time from injection to expected normal ovulation, injection level, and place of the follicle in the clutch ...
