Morphological and Histological Variations of the Reproductive Organs During the Annual Cycle in a Neotropical Bat: Peters' Ghost‐Faced Bat Mormoops megalophylla (Chiroptera: Mormoopidae)

Journal of Morphology, Volume 286, Issue 7, July 2025.
Mormoops megalophylla exhibits a seasonal monoestrous reproductive pattern. Spermatogenesis and folliculogenesis occurs from October to December, mating takes place in November–December, gestation lasts from December to May, and lactation extends from June to September.

Diagnosis and successful treatment of open pyometra in a wild European brown hare (Lepus europaeus)

Veterinary Record Case Reports, Volume 13, Issue 2, June 2025.
Abstract This case report describes an open pyometra in a wild adult female hare (Lepus europaeus) that was rescued in the Umbria countryside (Italy) during mid‐January. The clinical signs observed included anorexia and a mucopurulent to haemorrhagic discharge from the vulva.

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.

Induced placentitis after vaginal manipulation in two late pregnant alpacas

Veterinary Record Case Reports, Volume 13, Issue 2, June 2025.
Abstract Two prepartum female alpacas were referred to our institution with the presumed diagnosis of uterine torsion. In both cases, uterine torsion was not confirmed but bacterial placentitis with Escherichia coli as the aetiological agent was diagnosed.

Release of proinflammatory cytokines related to luteolysis and the periparturient acute phase response in prostaglandin-induced parturition in cows [PDF]

, 1998
An acute phase response was previously found in cows at parturition, which might be associated with uterine cytokine release. Five late pregnant cows were implanted with vascular catheters in both the maternal aorta and uterine vein.

Spontaneous Luteolysis in the Cyclic Golden Hamster: Evidence for Mediation Through Inflammation and Apoptosis [PDF]

, 1995
Mammalian corpora lutea (CL) are transient ovarian glands which function to support pregnancy by secretion of progesterone (P). Sustained P secretion during pregnancy in the hamster requires gonadotrophic support, i.e., follicle stimulating hormone (FSH)

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.

Difference in expression between AQP1 and AQP5 in porcine endometrium and myometrium in response to steroid hormones, oxytocin, arachidonic acid, forskolin and cAMP during the mid-luteal phase of the estrous cycle and luteolysis

Reproductive Biology and Endocrinology, 2015
BackgroundRecently, we demonstrated in vitro that AQP1 and AQP5 in the porcine uterus are regulated by steroid hormones (P4, E2), arachidonic acid (AA), forskolin (FSK) and cAMP during the estrous cycle.

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.

Luteal ANGPT-TIE system during selected stages of pregnancy, and normal and antigestagen-induced luteolysis in the dog

, 2018
Rapid establishment of a vascular network is essential for normal functionality of the corpus luteum (CL). The early luteal phase is associated with increased expression of the VEGF-system in canine CL.
