Luteolysis after the intravulvosubmucosal injection of prostaglandin F2α in cattle: Systemic or local mechanism? [PDF]

, 2012
The intravulvosubmucosal (IVSM) route has been used to reduce the dose of prostaglandin F2α (PGF2α), a luteolytic agent used in estrus synchronization programs.

Efficacy of Short‐Term Timed Artificial Insemination Protocols With Estradiol Esters and PGF2α in Girolando Cows

Reproduction in Domestic Animals, Volume 60, Issue 5, May 2025.
ABSTRACT Using a synchronisation protocol based on estradiol esters and prostaglandin, established in cattle since the 1970s, we implemented 24 or 48‐h intervals between hormone administration and timed artificial insemination (TAI). This study compared two short‐duration TAI protocols using estradiol benzoate (EB) and cypionate (EC) as ovulation ...

L‐Theanine Ameliorates Doxorubicin‐Induced Ovarian Toxicity by Reducing Endoplasmic Reticulum Stress

Food Science &Nutrition, Volume 13, Issue 4, April 2025.
L‐theanine is the most important nutraceutical compound in green tea. The aim of this study is to investigate for the first time whether LTN has any therapeutic effect on DOX‐induced ovarian toxicity, especially in terms of endoplasmic reticulum stress.

Systemic Changes in Early Pregnancy in the Mare: An Integrated Proteomic Analysis of Blood Plasma, Histotroph, and Yolk Sac Fluid at Day 14 Post‐Ovulation

PROTEOMICS – Clinical Applications, Volume 19, Issue 2, March 2025.
ABSTRACT Purpose Embryo‐maternal signaling during the establishment of pregnancy in horses remains one of the biggest mysteries in large animal physiology. Early pregnancy loss represents a major source of economic loss to the breeding industry. This study aimed to investigate the systemic changes associated with early pregnancy by mapping the proteome

Efficiency of cloprostenol-induced luteolysis in superovulated cows. [PDF]

, 2011
The objective of the first experiment was to compare the effi F, treatment on inducing luteolysis in embryo donors immediately after flushing (D7, superovulated with 400 TU of F of a single prostaglandin 24) or 4 days later (D11, N =22).

Double cloprostenol administration during mid luteal phase of oestrous cycle does not modify the interoestrous interval in gilts

Italian Journal of Animal Science, 2014
The present study was undertaken to test the effect of two vulva injections of D-cloprostenol on day 7, 9 and 10 of oestrous cycle on the duration of the interestrous interval in gilts.

Relationship between the timing of prostaglandin-induced luteolysis and effects on the conceptus during early pregnancy in mares [PDF]

, 2012
To advance the understanding of early pregnancy and pregnancy failure in horses, this study determined how luteolysis induced by cloprostenol (an analogue of prostaglandin F2α) affects conceptus development. Mares were injected on Days 12, 14, 16 or 18

Effect of stage of the estrous cycle at the time of initial exposure to rams on the ovarian activity of Pelibuey ewes

Czech Journal of Animal Science, 2014
Forty non-lactating, cyclic adult Pelibuey ewes were randomly divided into six groups. Estrus was synchronized within each group using intravaginal sponges and prostaglandin F2α injection at the time of the sponge removal.

Luteolysis in the mare: a role for the immune system and gonadotrophins? [PDF]

, 1998
The luteolytic process in the mare has been left relatively unexplored in recent times, while research has progressed considerably in our other domestic species.

Intra-ovarian dynamic blood flow in pseudopregnant rabbits during prostaglandin F2α-induced luteolysis [PDF]

, 2019
Contents In the present study, we evaluated the dynamic changes of intra-ovarian blood flow, by real-time colour-coded and pulsed Doppler ultrasonography, as well as the immunopresence of prostaglandin F2 (PGF2) receptor (FP) and peripheral plasma ...
