Studies based on treatment with antibodies to thyrotropic hormone, luteotropic hormone, growth hormone or adrenocorticotropic hormone have shown that although the unicellular Tetrahymena does not possess sui generis receptors to all polypeptide hormones, such binding structures may arise, or become established in the membrane of the unicellular Tetrahymena in the presence of exogenous hormone. ...

the experiment was designed to study the changes in production performance and egg quality of old laying hens after injection of different doses of growth hormone (gh) and testosterone (ts). a total of 160 old laying hens (hyline w-36) at 73 wks of age were randomly assigned to four treatments with four replicates and 10 birds in each replicate in a completely randomized design. treatment group...

Background: Insecticides may have negative effects on reproductive organs. Given the interaction between leptin and the hypothalamic-pituitary-gonadal (HPG) axis, we sought to investigate the changes in leptin and the HPG axis in adult male rats poisoned with Proteus and Biscaya insecticides. Methods: Our experimental subjects were 110 adult male Wistar rats (80–90 days of age; average weight=2...

Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...
