In female rats bearing an average litter of 10 ± 0·28 fetuses, pituitary prolactin is secreted in a pattern of two daily surges during the first 10 days of pregnancy only. When the number of fetuses was experimentally reduced, prolactin surges continued for a longer period and pregnancy was correspondingly lengthened.

Exposure to dexamethasone reduces pituitary volume and gonadotropic cell number in rat fetuses
Acta Histochemica, 2014Overexposure to glucocorticoids during the fetal period induces changes in developmental processes in various fetal tissues. The aim of this study was to investigate the effects of the synthetic glucocorticoid, dexamethasone (Dx), on pituitary volume and gonadotropic cells during a critical period of pituitary development.

Effect of number of corpora lutea and fetuses on concentrations of progesterone in blood of goats.
Journal of Animal Science, 1991The objectives of this study were to assess relationships between 1) number of corpora lutea (CL) and concentrations of progesterone (P) in plasma of goats from onset of estrus (d 0) to d 45 of pregnancy and 2) concentration of P and number of fetuses on d 45.

Ovulation rate, number of fetuses and embryo loss in Teddy goats of Pakistan
Small Ruminant Research, 1999Abstract The genitalia of 107 pregnant Teddy goats of different ages were collected from an abattoir. Ovulation rate, number of fetuses, embryo loss and location of fetuses in the uterine horns relative to number of corpora lutea in the ovaries were recorded. In goats with no permanent teeth, with two permanent teeth, four permanent teeth, and six or

This study examined the effects of aminoglutethimide phosphate (AGP) administration on the incidence of pregnancy and number of live fetuses in superovulated rats. Immature (31- to 33-day-old) young (8- to 9-week-old) and (14- to 16-week-old) rats were treated with 20 or 40 IU of PMSG and the same dosses of hCG at 52 to 54 hour-intervals (GTH rats ...

Decreased number of sperms and Sertoli cells in mature rats exposed to diesel exhaust as fetuses
Toxicology Letters, 2005This study was conducted to follow up the effects of fetal exposure to diesel exhaust on testicular cell numbers and daily sperm production in adulthood. Thirty-six pregnant rats were divided into five groups: groups exposed to total diesel-engine exhaust containing 1.71 mg/m3 particulate matter and 0.80 ppm nitrogen dioxide (high dose) or 0.17 mg/m3 ...

The effects of dexamethasone on nucleic acid synthesis and cell numbers in rat fetuses.
Experimental and clinical endocrinology, 1983Pregnant rats were treated with dexamethasone in drinking water (10 micrograms/ml) from the 15th to the 22nd day of pregnancy. Dexamethasone significantly depressed cell numbers in fetal rat adrenal glands, liver, lung, testes and pituitary from the 17th to the 22nd day of pregnancy.
