Effect of Royal Jelly on Sperm Parameters and Testosterone Levels in Infertile Men
Background and purpose: Complementary medicine plays a major role in treatment of infertility. The aim of this study was to evaluate the effect of royal jelly on sperm parameters and testosterone levels in infertile men. Materials and methods: In this quasi-experimental study, 100 infertile men attending the infertility treatment center in Sari Imam Khomeini Hospital were monitored for two mon...
متن کاملAging alters feed-forward and feedback linkages between LH and testosterone in healthy men.
To discern the effect of aging on coordinate luteinizing hormone (LH) and testosterone secretion, we sampled healthy older men (age 62-74 yr, n = 11) and young controls (age 21-34 yr, n = 13) every 2.5 min overnight. Deconvolution analysis and cross-correlation were used to relate serum LH concentrations to calculated testosterone secretion rates (feed-forward stimulation), as well as serum tes...
متن کاملMen in committed, romantic relationships have lower testosterone.
Variation in human male testosterone levels may reflect, and effect, differential behavioral allocation to mating and parenting effort. This proposition leads to the hypothesis that, among North American men, those involved in committed, romantic relationships will have lower testosterone levels than men not involved in such relationships. Our study is the first to examine whether being in such...
متن کاملTestosterone levels and bone mineral density in young healthy men and in young infertile patients.
OBJECTIVES. Although relatively little information exists concerning bone mineral density (BMD) in men, it has been demonstrated that similarly to observations in women, BMD decreases also with age in men, although to a smaller extent, and osteoporosis is increasingly recognized. Most reports concentrate, however, on men of advanced age. Therefore, we decided to investigate BMD in young healthy...
متن کاملTestosterone dose-response relationships in healthy young men.
Testosterone increases muscle mass and strength and regulates other physiological processes, but we do not know whether testosterone effects are dose dependent and whether dose requirements for maintaining various androgen-dependent processes are similar. To determine the effects of graded doses of testosterone on body composition, muscle size, strength, power, sexual and cognitive functions, p...
