Tribulus terrestris is an annual herb of the Zygophyllaceae family and is commonly known as Gokshur, Gokharu, or puncturevine. Flavonoids, alkaloids, saponins, lignin, amides, and glycosides are the main active phytoconstituents of this plant. Infertility is defined by the failure to conceive a child after one year or more of regular unprotected sexual intercourse. Infertility affects society at large and has a negative impact on the social and emotional aspects of the patient. This in-depth review presents several studies that evaluate the role of Tribulus terrestris in a chronological order to help us better understand the exact mechanism by which this herbal medicine acts in male infertility...

Rooster fertility peaks between 30 and 40 weeks of age and declines rapidly from 50 weeks of age. This is linked to a reduction in the number of spermatozoa in the ejaculate due to high density of spermatids in the seminiferous tubules of low-fertility roosters. In this study, we assessed the effects over spermatogenesis of both letrozole, an aromatase inhibitor, and a commercial herbal extract designed for improving fertility composed by Tribulus, Cinnamomum, Zingiber and Sativus. Forty-two-week-old Ross 308 roosters (n = 24) were distributed into four groups: control, letrozole (0...
