BMP15 regulates the inhibin/activin system independently of ovulation rate control in sheep [PDF]

, 2017
Polymorphisms in the gene encoding bone morphogenetic protein 15 (BMP15) have been associated with multiple ovulations in sheep. As BMP15 regulates inhibin expression in rodents, we assumed that the ovarian inhibin/activin system could mediate part of ...

Granulosa cell proliferation is inhibited by PGE2 in the primate ovulatory follicle

Animal Cells and Systems, 2020
Prostaglandin E2 (PGE2) is a key paracrine mediator of ovulation. Few specific PGE2-regulated gene products have been identified, so we hypothesized that PGE2 may regulate the expression and/or activity of a network of proteins to promote ovulation.

Association between menstrual cycle phases and exposure to environmental contaminants— Menstrual Cycle and Ovulation Study 2 (MOS2)

, 2022
In 2006-2008, 610 premenopausal, spontaneously menstruating women in the Metro Vancouver region participated in a Canadian Institutes of Health Research (CIHR)-funded singlecycle in which they collected first morning urine specimens for estrogen and ...

Dissection of the Ovulatory Process Using ex vivo Approaches

Frontiers in Cell and Developmental Biology, 2020
Ovulation is a unique physiological phenomenon that is essential for sexual reproduction. It refers to the entire process of ovarian follicle responses to hormonal stimulation resulting in the release of mature fertilization-competent oocytes from the ...

Treating Mares with the Long-Acting Kisspeptin Analog C6 Increases Circulating Gonadotropins but Does Not Trigger Ovulation

Agriculture, 2022
The role of the neuropeptide kisspeptin (Kp) in mammalian reproduction is well established. Nevertheless, species-specific differences exist. In the horse, administration of the shortest endogenous Kp isoform, Kp10, is unable to trigger ovulation even ...

Ovulation and rate of implantation following unilateral ovariectomy in mice

Journal of Human Reproductive Sciences, 2013
Objectives: Removal of an ovary of any side of the body is called the unilateral ovariectomy (ULO). ULO models are used to analyze the existence of functional and physiological asymmetries between the ovaries, including the ovum implantation.

Induced Spawning of F1 Wreckfish (Hāpuku) Polyprion oxygeneios Using a Synthetic Agonist of Gonadotropin-Releasing Hormone

Fishes, 2019
Wild-caught hāpuku (Polyprion oxygeneios) spawn readily in captivity, but although first filial (F1) hāpuku complete vitellogenesis, females fail to undergo oocyte maturation and spawn or produce poor quality eggs.

Reproductive management in pigs: emphasis on the different roles of the boar and on optimal insemination management

, 2009
Boars have different roles in the reproductive management in pigs. Boar contact can stimulate follicle development and thereby induce oestrus, both in gilts and sows.
