Progesterone significantly enhances the mobility of boar spermatozoa [PDF]

open access: yes, 2013
Progesterone released from the cumulus cells of the oocyte causes a number of physiological responses in human sperm cells including hyperactivation, acrosome reaction and chemotaxis. We employed a validated sperm mobility assay, which involves measuring

Production of a soluble and functional recombinant apolipoproteinD in the Pichia pastoris expression system [PDF]

open access: yes, 2016
ApolipoproteinD (ApoD) is a human glycoprotein from the lipocalin family. ApoD contains a conserved central motif of an 8-stranded antiparallel β-sheet, which forms a beta-barrel that can be used for transport and storage of diverse hydrophobic ligands ...

Membrane progesterone receptor beta (mPRβ/Paqr8) promotes progesterone-dependent neurite outgrowth in PC12 neuronal cells via non-G protein-coupled receptor (GPCR) signaling

open access: yesScientific Reports, 2017
Recently, sex steroid membrane receptors garnered world-wide attention because they may be related to sex hormone-mediated unknown rapid non-genomic action that cannot be currently explained by their genomic action via nuclear receptors.

Short oestrous cycles in sheep during anoestrus involve defects in progesterone biosynthesis and luteal neovascularisation [PDF]

open access: yes, 2014
Anoestrous ewes can be induced to ovulate by the socio-sexual, 'ram effect'. However, in some ewes the induced ovulation is followed by an abnormally short luteal phase causing a so called, "short cycle".

Predictive Value of Serum Progesterone Levels on The Day of Frozen-Thawed Embryo Transfer in Determining Pregnancy Outcomes in Infertile Women: A Cohort Prospective Study [PDF]

open access: yesInternational Journal of Fertility and Sterility
Background: Hormone replacement therapy (HRT) is the preferred protocol for endometrial preparation. Progesterone is important for successful implantation and the outcome of assisted reproductive techniques (ART).
