The "Ram Effect": A "Non-Classical" Mechanism for Inducing LH Surges in Sheep [PDF]

, 2016
During spring sheep do not normally ovulate but exposure to a ram can induce ovulation. In some ewes an LH surge is induced immediately after exposure to a ram thus raising questions about the control of this precocious LH surge.

Effects of Lateral Hypothalamic Lesions on Placentophagia in Virgin, Primiparous, and Multiparous Rats [PDF]

, 1973
Lesions of the lateral hypothalamus (LH) were produced in pregnant and nonpregnant female rats through chronically implanted electrodes to investigate the effect of LH damage on placentophagia.

Effect of aqueous rosemary extract on some sexual hormones in male rats with high thyroxine level [PDF]

Iraqi Journal of Veterinary Sciences, 2021
The main purpose of this research is to evaluate the high level of thyroxine affects on each of the luteinizing hormone (LH), testosterone, follicle-stimulating hormone (FSH) of rats and to estimate the potential effect of the administration of aqueous ...

Serum LH/FSH ratios in 87 infants with differences of sex development

Endocrine Connections, 2023
The ratio between luteinizing hormone (LH) and follicle-stimulating hormone (FSH) has previously been described as an excellent marker of sex in healthy infants. However, LH/ FSH remains not fully described in patients with differences of sex development

Sex Steroid Inhibition of LH Induction of the LH Receptor [PDF]

Journal of Andrology, 1987
Testosterone and estrogen were tested as possible mediators of the prolactin‐dependent LH induction of LH receptors in hypophysectomized adult male rats. Animals were injected s.c. with saline, prolactin (100 μg/day), or combinations of testosterone (1 mg/day) or estrogen (1 mg/day) and prolactin for 7 days following a 7‐day period of hypophysectomy ...

Decoding odor quality and intensity in the Drosophila brain [PDF]

, 2014
To internally reflect the sensory environment, animals create neural maps encoding the external stimulus space. From that primary neural code relevant information has to be extracted for accurate navigation.

Does size matter? The integrated roles of light, adaptive sex expression, and hybridization in a widespread Arisaema (Araceae) species from western Japan [PDF]

Plant Ecology and Evolution
Background and aims – Reproductive plasticity and hybridization are known to play key roles in local adaptation and range expansion in plants, yet the environmental conditions under which canonical size-dependent models of sex expression break down ...

Newly identified cold subdwarfs - LHS 375, LHS 407, LHS 3181, and LHS 3555

The Astronomical Journal, 1993
Four new cold subdwarfs have been identified from Luyten's LHS Catalogue (1976), LHS 375, LHS 407, LHS 3181, and LHS 3555. CCD B, V, R, and I photometry; infrared J, H, and K photometry and spectra of the stars have been obtained. We discuss their location in different color-color diagrams.

Combinatorial algebra for second-quantized Quantum Theory [PDF]

, 2010
We describe an algebra G of diagrams that faithfully gives a diagrammatic representation of the structures of both the Heisenberg–Weyl algebra H – the associative algebra of the creation and annihilation operators of quantum mechanics – and U(LH), the ...

Investigate the Correlation of Growth Hormone with the Level of Some Reproductive Hormones and Certain Parameters in a Number of Iraqi-Aging and Younger Women During IVF/ICSI Cycles [PDF]

Kirkuk Journal of Science, 2023
An estimated 12–20% of couples struggle with infertility, which is described as not becoming pregnant after a year of trying. About one-third of these couples are infertile because of female factors, and another third are infertile because of male ...
