title: Drug abuse and reproduction.
abstract: It is clear that a number of CNS agents, including drugs of abuse, can inhibit reproductive function. Figure 1 shows the chemical diversity of some of the drug groups that affect reproductive hormones. Their structural dissimilarity to the steroid hormones is also readily apparent in the figure. These chemically diverse drugs share an important pharmacologic property: they are highly potent neuroactive drugs, and they can disrupt hypothalamic-pituitary function. Although it is frequently difficult to distinguish between direct drug actions on the hypothalamic-pituitary axis and subsequent effects on gonadal hormones and sex accessory gland function, the distinction is an important one. Most neuroactive drugs produce only transient effects on the central nervous pathways necessary for normal gonadotropin secretion. The disruptive effects of these drugs are likely to be transient and completely reversible, and tolerance to the inhibitory drug effects may occur even with continued drug use. Under these circumstances, normal adults may experience only subtle changes in sexual function. However, individuals with compromised reproductive function may exhibit major problems. It is also likely that adolescents may be at substantial risk for reproductive damage from these neuroactive drugs since the endocrine events associated with puberty are dependent on the normal development of the hypothalamic-pituitary axis.
