Phenobarbital exposure in utero: alterations in female reproductive function in rats. 1980

C Gupta, and B R Sonawane, and S J Yaffe, and B H Shapiro

Phenobarbital administration to pregnant rats from day 12 to day 19 of gestation suppressed body weight gain and produced significant effects on reproductive function in their offspring. These effects included delays in the onset of puberty, disorders in the estrous cycle, and infertility. Moreover, the animals exposed to phenobarbital in utero showed altered concentrations of sex steroids, gonadotrophic hormones, and estrogen receptors. These findings suggest that phenobarbital treatment during prenatal development can produce permanent alterations in sexual maturation.

UI	MeSH Term	Description	Entries
D007986	Luteinizing Hormone	A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

D008431	Maternal-Fetal Exchange	Exchange of substances between the maternal blood and the fetal blood at the PLACENTA via PLACENTAL CIRCULATION. The placental barrier excludes microbial or viral transmission.	Transplacental Exposure,Exchange, Maternal-Fetal,Exposure, Transplacental,Maternal Fetal Exchange
D010634	Phenobarbital	A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.
