long-term sequelae 1,3-dinitrobenzene male reproduction rat
2009/2/23
Groups of eight adult male rats were given a single oral dose of 0 or 48 mg/kg of 1,3-dinitrobenzene and sacrificed at 1, 2, 4, 8, 16, 24, 32, 72, and 175 days posttreatment. The groups killed at 17...
A Method for Improvement of Sperm Quality of an Ejaculated Human Specimen Using Bovine Cervical Mucus as a Biological Filter
teratozoospermia bovine cervical mucus penetration test
