Their effects can be desired (hormonal contraception), a minor unwanted side effect (many antidepressants) or; a major public health problem (thalidomide). However, most studies of reproductive toxicity have focused on occupational or environmental exposure to chemicals and their effects on reproduction.
Another common toxin is pyrifluquinazon, which is an insecticide used to control pests. Vinclozolin is also an endocrine disrupting chemical; it is a fungicide used on produce to help them have a longer shelf life . [21] Endocrine disruptors may have different effects depending on the extent of the exposure. [22]
Common side effects include sleepiness, rash, and dizziness. [6] Severe side effects include tumor lysis syndrome, blood clots, and peripheral neuropathy. [8] Thalidomide is a known human teratogen and carries an extremely high risk of severe, life-threatening birth defects if administered or taken during pregnancy. [6]

Cyclopamine (11-deoxojervine) is a naturally occurring steroidal alkaloid.It is a teratogenic component of corn lily (Veratrum californicum), which when consumed during gestation has been demonstrated to induce birth defects, including the development of a single eye in offspring. [1]
