Cervical mucus changes in infertile ewes previously exposed to oestrogenic subterranean clover. 1976

N R Adams

Characteristics of cervical mucus were compared between groups of ewes which had previously grazed for long periods on either potently oestrogenic clover pasture (group A), mildly oestrogenic pasture (group B) or non-oestrogenic pasture (group C). No phytooestrogens were fed at the time of the study. The chloride content of mucus from group A ewes was significantly decreased, on a dry weight basis. The motility and survival of ram spermatozoa appeared similar in cervical mucus from groups A and B. There was no statistically significant difference between groups of ewes in either the total wet weight of mucus, the proportion of dry weight, or the degree of arborisation of mucus, at the time of oestrus. Mucus from group A ewes had a significantly decreased spinbarkheit, and a decreased ability to orientate sperum migration, when compared with group B. The group B ewes had a significantly smaller spinbarkheit than group C. Measurement of cervical mucus spinbarkheit offers promise as a diagnostic test for permanent clover infertility.

D010939	Plant Poisoning	Poisoning by the ingestion of plants or its leaves, berries, roots or stalks. The manifestations in both humans and animals vary in severity from mild to life threatening. In animals, especially domestic animals, it is usually the result of ingesting moldy or fermented forage.	Poisoning, Plant,Plant Poisonings,Poisonings, Plant
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D002582	Cervix Mucus	A slightly alkaline secretion of the endocervical glands. The consistency and amount are dependent on the physiological hormone changes in the menstrual cycle. It contains the glycoprotein mucin, amino acids, sugar, enzymes, and electrolytes, with a water content up to 90%. The mucus is a useful protection against the ascent of bacteria and sperm into the uterus.

D004967	Estrogens	Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
