Estrus Synchronization in Awassi and Red Karaman Fat Tailed Ewes

, 2003
To evaluate the efficacy of estrus synchronization procedures 60 Awassi and 44 Red Karaman ewes were equally divided into 2 groups each. To synchronize estrus sheep in one group from each breed (group 1 and 2) were injected intramuscularly with PGF2α (1 ...

Optical control of the hypothalamic arcuate nucleus kisspeptin neuronal network with a photoswitchable peptide that drives luteinizing hormone release in female mice

Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Pulsatile gonadotropin‐releasing hormone (GnRH) and luteinizing hormone (LH) secretion are essential for reproductive function and are thought to be governed by arcuate nucleus kisspeptin Kiss1ARH neurons via neurokinin B (NKB) signaling through TacR3.

SYNCHRONIZATION OF ESTRUS IN EWES

The Iraqi Journal of Veterinary Medicine, 1987
A group of 15 Awasi ewes were inserted with intravaginal sponges of Veramix plus which were removed thirteen days later. Immediately after removal of the sponges, they were injected with 500 IU of FSH intramuscularly. All ewes were came to estrus within 2-3 days after injection.

Intracerebroventricular injection of neuropeptide Y suppresses luteinizing hormone pulses in mice

Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Stress impairs reproduction, at least in part, by inhibition of Kisspeptin/Neurokinin B/Dynorphin (KNDy) cells and suppression of gonadotropin secretion. However, the mechanism for this inhibition is not clear. Neuropeptide Y (NPY) is a pleiotropic molecule that is produced in neurons throughout the brain and mediates several physiological ...

Pregnancy Outcomes Following Artificial Insemination and Embryo Transfer in Dairy Cows—Expectations vs. Reality

Reproduction in Domestic Animals, Volume 61, Issue S2, September 2026.
ABSTRACT Bovine embryo transfer (ET) has been a consistently growing market worldwide with in vitro produced (IVP) embryos now far outnumbering those produced by traditional superovulation. Because transfer of a viable blastocyst‐stage embryo to the uterus bypasses many of the potential biological causes of early pregnancy failure associated with ...
