Mossman-Pacey paradox

ArguMentor:


The '''Mossman-Pacey paradox''' is a [[evolution|evolutionary]] [[Irony#Situational_irony|irony]] in which certain actions often taken by men to improve their [[sexual attractiveness]] end up lowering their [[fertility]].<ref name="bbc">Liquid error: wrong number of arguments (1 for 2)</ref><ref name="newsweek">Liquid error: wrong number of arguments (1 for 2)</ref><ref>Liquid error: wrong number of arguments (1 for 2)</ref>

One of the most prevalent examples of this phenomenon is the use of [[anabolic steroids]] by some men (particularly if they go to the [[gym]]). These steroids can help build larger [[muscles]], but can also lead to side effects such as smaller [[testicles]], [[erectile dysfunction]], and lower [[sperm]] count.<ref name="newsweek" /> One of the main reasons for this is that anabolic steroids can stop the [[pituitary gland]] producing the [[hormones]] [[Luteinizing hormone|LH]] and [[Follicle-stimulating hormone|FSH]].<ref name="newsweek" /> It has been estimated that approximately 90% of anabolic steroid users are at risk of [[infertility]].<ref name="newsweek" />

Another major example is that the use of [[Hair loss|balding]] medications such as [[finasteride]] can reduce fertility.

== Etymology ==
The term is named after Dr James Mossman and Professor Allan Pacey, who first discovered the phenomenon when they noticed a large number of muscular men needing fertility tests.<ref name="newsweek" />
