Distribution and size of corpora lutea in dairy cows during puerperium [PDF]

Biotechnology in Animal Husbandry, 2018
During puerperium phase in cows, uterus goes through involution process, while ovaries restore supressed cyclicity as a result of gestation. After 10-20 days postpartum (PP) luteinizing hormone (LH) levels begin to raise and renewal of cyclicity after ...

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Comprehensive diagnostic and therapeutic approach to male factor infertility aimed at natural fertility: A multicentric retrospective cohort study

Andrology, EarlyView.
Abstract Background In infertile couples whose male partner has alterations in semen parameters frequently, a comprehensive andrological approach is lacking and approximately 30–50% are classified as idiopathic infertility. These couples are often directly addressed to assisted reproduction techniques (ARTs).

Riemannian L-systems: Modeling growing forms in curved spaces [PDF]

arXiv
In the past 50 years, the formalism of L-systems has been successfully used and developed to model the growth of filamentous and branching biological forms. These simulations take place in classical 2-D or 3-D Euclidean spaces. However, various biological forms actually grow in curved, non-Euclidean, spaces.

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

ILETIA: An AI-enhanced method for individualized trigger-oocyte pickup interval estimation of progestin-primed ovarian stimulation protocol [PDF]

arXiv
In vitro fertilization-embryo transfer (IVF-ET) stands as one of the most prevalent treatments for infertility. During an IVF-ET cycle, the time interval between trigger shot and oocyte pickup (OPU) is a pivotal period for follicular maturation, which determines mature oocytes yields and impacts the success of subsequent procedures. However, accurately

Maternal time interval between menarche and childbirth is associated with daughter's age at menarche

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Using data from the Norwegian MoBa study, we found that mothers who give birth shortly after their own menarche have daughters with a lower likelihood of early menarche. Abstract Introduction Women's reproductive lifespan has increased over the past two decades.

Reproductive sterility in aquaculture: A review of induction methods and an emerging approach with application to Pacific Northwest finfish species

Reviews in Aquaculture, Volume 15, Issue 1, Page 220-241, January 2023., 2023
Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from
