Animal
. 2023 Aug;
17 Suppl 1:100754.
PMID: 37567661
The actions of the beta-nerve growth factor (β-NGF) on the neuroendocrine and reproductive system have challenged classical views on the control of reproductive function. After endometrial absorption, β-NGF triggers ovulation...

PMID: 36978545
The neurotrophin beta-nerve growth factor (NGF), which is present in the semen of different mammals, elicits potent ovulatory and luteotrophic actions in llamas following systemic administration. Here, we determine if...

PMID: 36757313
In Brief: Seminal nerve growth factor induces ovulation in camelids by influencing the secretion of gonadotrophin-releasing hormone (GnRH) into the portal vessels of the pituitary gland. We show that the...

PMID: 35565530
The morphological quality and the in vitro developmental competence of cumulus-oocyte complexes (COCs) collected from in vivo or slaughtered alpacas was compared. COCs were recovered from ovarian follicles using: (i)...

New Insights Into the Role of β-NGF/TrKA System in the Endometrium of Alpacas During Early Pregnancy
Barraza D, Sari L, Apichela S, Ratto M, Arganaraz M
Front Vet Sci
. 2021 Feb;
7:583369.
PMID: 33553274
One striking reproductive feature in South American camelids is that more than 90% of gestations are established in the left uterine horn (LUH). This phenomenon could be related to a...
