Impact of exposure to diesel exhaust during pregnancy on mammary gland development and milk composition in the rabbit.

Exposure to fine-particulate air pollution is a major global health concern because it is associated with reduced birth weight and an increased risk of cardiovascular disease. Here we have investigated the potential for exposure to diesel exhaust during pregnancy to influence mammary gland development and milk composition. Female rabbits were therefore exposed by nose-only inhalation to either diluted diesel exhaust fumes (1 mg/m3) or clean air for 2h/day, 5 days/week, from the 3rd to the 27th days of pregnancy.

Impact of maternal hyperlipidic hypercholesterolaemic diet on male reproductive organs and testosterone concentration in rabbits.

The concept of Developmental Origins of Health and Disease initially stemmed from the developmental programming of metabolic diseases. Reproductive functions and fertility in adulthood may also be programmed during foetal development. We studied the impact of dietary-induced maternal hyperlipidaemia and hypercholesterolaemia (HH), administered at 10 weeks of age and throughout the gestation and lactation, on male reproductive functions of rabbit offspring.
