Estrogen associated changes in uterine blood flow and maternal recognition of pregnancy in Chinese (Meishan) pigs






Animal Reproduction Science 36(1-2): 135-143

Estrogen associated changes in uterine blood flow and maternal recognition of pregnancy in Chinese (Meishan) pigs

This experiment examined the hypothesis that oestrogen secretion by the preimplantation conceptus increases uterine blood flow (UBF) and the onset of maternal recognition of pregnancy in Meishan pigs.

In Chinese Meishan pig embryonic mortality appears relatively low compared to European breeds. Most of embryonic loss in pig is believed to take place during early pregnancy. It is of interest to know possible specific features associated with low...

Assumptions were made: that the porcine purple intra-uterine glycoprotein and prostaglandin [PG] F2.alpha. are synthesized and secreted by epithelial cells of the uterine endometrium; that the purple glycoprotein and PG F2.alpha. can move into eit...

Bazer, F.W.; Thatcher, W.W., 1976: Theory of maternal recognition of pregnancy in swine based on estrogen controlled endocrine versus exocrine secretion of prostaglandin F2 alpha by the uterine endometrium. From a review of the literature, it is concluded that in the non-pregnant female , progesterone enhances and/or induces PGF synthesis and secretion. The PGF flows into the uterine venous drainage system and ultimately reaches the corpora lutea to...
