TL;DR: HN acts directly on germ cells to protect against EDS‐induced apoptosis in the absence of Leydig cells and intratesticular testosterone levels are very low and is not effective in preventing the reduction of T production by KTZ in vitro.

TL;DR: Differences in androgens and estrogen levels in men over the age of 20 yr in a population that is representative of the United States and differed from other earlier studies by the large number of subjects studied spanning a wide age range across the nation are reported.

TL;DR: Potential risks and benefits of putative male hormonal contraceptives on reproductive and non-reproductive organs are summarized and what will be the likely class of drugs used for male hormonal contraception is covered.

TL;DR: Results of this study indicate enchomiphene citrate, like E2, has a direct inhibitory effect on the testis, whereas high doses of these compounds further decrease testicular LH/hCG receptor content and spermatogenesis.

TL;DR: The sixth edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen, launched in 2021, can be freely downloaded from the WHO website, with the hope of gaining wide acceptance and utilization as the essential source of the latest, evidence-based information for laboratory procedures required for the assessment of male reproductive function and health as mentioned in this paper .
