Neuroendocrinology of melatonin in reproduction: recent developments
TLDR
The recent demonstration of 2[125I]iodomelatonin binding sites or melatonin receptors in the testis, epididymis, vas deferens, prostate, ovary and mammary gland suggest the concept of multiple sites of melatonin action on the reproductive system. Expand
Asymmetrical testicular weights in mammals, birds, reptiles and amphibia.

  • Biology, Medicine
  • International journal of andrology
  • 1 April 1998
TLDR
The testes of different classes of animals (mammals, birds, reptiles and amphibia) were weighed, and some species showed inconsistent left-right asymmetric testicular weights, while other species showed consistent asymmetry in their weights. Expand
Gossypol as a male antifertility agent--why studies should have been continued.
TLDR
Confusion surrounding issues such as hypokalaemia, irreversible azoospermia and other side effects are pointed out and the prospects and related difficulties for gossypol as a potential male contraceptive are discussed. Expand
Identification and characterization of 2[125I]‐iodomelatonin binding sites in the rat epididymis
TLDR
Identification and characterization of 2[125I]iodomelatonin binding sites in the rat epididymis and their role inatonin secretion is described. Expand
4-bromo-7-hydroxyindan oxime--a new potent spermicidal agent.
TLDR
The spermicidal effect of eleven chelating agents with a ring structure was evaluated using human spermatozoa and 4-Bromo-7-hydroxyindan oxime (S-11) was the most potent and its lowest effective concentration for immobilizing sperm within 20 sec was 0.02 mg/ml. Expand

  • 1 December 1982
TLDR
As a spermatocide, BAL was less effective than salicylaldehyde, o-vanillin, 8-hydroxyquinoline and gossypol, but three water-soluble chelating agents did not kill the sperms directly. Expand
Gossypol and hypokalemia: a critical review.
TLDR
Evidence on the notion of gossypol-induced hypokalemia is reanalyze and it is suggested that an unknown cause rather than gOSSypol was the true cause for the observed hypkalemia in gossYPol takers. Expand
[Antifertility actions of gossypol derivatives and analogues].
TLDR
Among 12 compounds screened by oral administration to male rats, only dipotassium gossypolate (NC030) exhibited an antifertility activity similar to gOSSypol. Expand
Electrolytes, protein, and lactate dehydrogenase isozymes of parotid saliva in mineralocorticoid-treated rats.
  • Z. H. Yu
  • Chemistry, Medicine
  • Canadian journal of physiology and pharmacology
  • 1 June 1992
TLDR
Saliva showed significant increases in potassium and protein and a decrease in sodium; lactate dehydrogenase-2 and -4 bands appeared darker on the electrophoretic profile, relevant to the clinical manifestations and diagnosis of hypokalemia. Expand
