In addition, consumption of animal byproducts contaminated with these antimicrobials may result in nephropathy, anaphylaxis and teratogenesis (Kools et al., 2008).
[11-13] A limited number of studies have investigated the perspectives and practices of women exposed to potentially teratogenic substances to identify high-risk behaviour and attitudes that could contribute to congenital abnormalities due to teratogenesis. [14-16] International studies have evaluated patients' knowledge and practice with regard to their warfarin treatment in terms of side-effects of bleeding, precautions, monitoring of levels and emergency management.
Obvious concerns about lithium during pregnancy have focused on increased risk of teratogenesis, with the earliest reports supporting an increased risk of Epstein's anomaly (0.05%-0.1%).
Both of these malignancies have a predilection for location in the isthmus, probably related to teratogenesis during embryological development (Krishnan et al.).

Cereblon (CRBN), a substrate adaptor of E3 ubiquitin ligase, was identified as the primary target for lenalidomide-induced teratogenesis.[3] The pharmacologic mechanism of action includes binding to the CRL4CRBN E3 ubiquitin ligase complex (E3 complex) through CRBN and modulating substrates (such as IKZF1 and IKZF3), which leads to the interference with life circle of cells.
CT is of limited use in obstetric patients, because of concerns about radiation-induced teratogenesis.
It has been shown in many studies that electromagnetic frequency (EMF) emitted by mobile phones interferes with the working of implanted cardiac pacemakers.[8-10] The effects of mobile phone radiations range from trivial symptomatology such as headache, nausea, and dizziness to more dreaded effects such as teratogenesis.[11] Some studies reported cataracts, skin burns, miscarriages, or birth defects due to negative thermic effects on living organisms.[12-15] On the contrary, some of the studies have shown no harmful effects on the body including cardiovascular parameters.[16-18]

However, when thinking about even a remote risk of teratogenesis, it's important to understand that fetal organogenesis occurs from day 15 to day 56, and that before 15 days, adverse events are limited to spontaneous abortion.
Resulting apoptosis and growth failure of the branchial arches disrupt development of all its derivatives including the thymus.2 Moreover, RA induces its teratogenesis, via multiple pathways.
