We presently review the biophysical mechanisms of lead poisoning that contribute to male infertility. Environmental and occupational exposure of lead may adversely affect the hypothalamic\u2212pituitary\u2212testicular axis, impairing the induction of spermatogenesis. Dysfunction at the reproductive axis, namely testosterone suppression, is most susceptible and irreversible during pubertal development. Lead poisoning also appears to directly impair the process of spermatogenesis itself as well as sperm function. Spermatogenesis issues may manifest as low sperm count and stem from reproductive axis dysfunction or testicular degeneration. Generation of excessive reactive oxygen species due to lead-associated oxidative stress can potentially affect sperm viability, motility, DNA fragmentation, membrane lipid peroxidation, capacitation, hyperactivation, acrosome reaction, and chemotaxis for sperm-oocyte fusion, all of which can contribute to deter fertilization. Reproductive toxicity has been tested through cross-sectional analysis studies in humans as well as\n                    <jats:italic>in vivo<\/jats:italic>\n                    and\n                    <jats:italic>in vitro<\/jats:italic>\n                    studies in animals.\n                  <\/jats:p>","DOI":"10.1017\/s0967199417000028","type":"journal-article","created":{"date-parts":[[2017,2,10]],"date-time":"2017-02-10T07:39:12Z","timestamp":1486712352000},"page":"103-110","source":"Crossref","is-referenced-by-count":97,"title":["Impaired hypothalamic-pituitary-testicular axis activity, spermatogenesis, and sperm function promote infertility in males with lead poisoning"],"prefix":"10.1017","volume":"25","author":[{"given":"Jason","family":"Gandhi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael J.","family":"Hernandez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noel L.","family":"Smith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yefim R.","family":"Sheynkin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gargi","family":"Joshi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sardar Ali","family":"Khan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2017,2,10]]},"reference":[{"key":"S0967199417000028_ref042","first-page":"193","article-title":"Lead exposure and oxidative stress: a systematic review","volume":"236","author":"Lopes","year":"2016","journal-title":"Rev.
