Teratogenicity01:07

Teratogenicity

4.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

概括

诸如人工授精 (AI),胚胎移植 (ET) 和细胞体内精子注射 (ICSI) 等生殖生物技术不会影响小羊的新生儿行为. 诸如农场管理和品种等因素对小的结果有更大的影响.
