Permanent infertility in ewes exposed to plant oestrogens
Australian Veterinary Journal, 1990SUMMARY In Australia, more than 1 million ewes have permanently damaged reproductive tracts because they have been grazed on oestrogenic pasture. These effects occur in the absence of classical clinical “clover disease”. The lesions result from an “organisational” action of oestrogen, causing a mild sexual transdifferentiation to occur in ewes during ...

Plant Products in the Management of Male Infertility
2017Male infertility is a disorder with an undefined etiology in about half of the cases. It has devastating effects on personal and social life of a couple. In the past few years, the modern medical sciences have prospered a lot; however, in spite of great advancements in synthetic products, the herbal products are still a preferred choice in terms of ...

Efficacy of Aphrodisiac Plants towards Improvement in Semen Quality and Motility in Infertile Males
Journal of Complementary and Integrative Medicine, 2012Infertility is the inability to conceive after one year of unprotected intercourse. In the present study, herbal composition prepared by using medicinal plants having aphrodisiac potentials was administered orally to the albino rats for 40 days and to the oligospermic patients for 90 days in order to prove the efficacy of herbal composition.

Causes of infertility in the endangered Australian endemic plant Borya mirabilis (Boryaceae)
Australian Journal of Botany, 2015Borya mirabilis Churchill (Boryaceae, Asparagales) is a herbaceous perennial and one of Australia’s most endangered plants. Only one population of four colonies remains, on a rock ledge in the Grampians (Gariwerd) National Park in Victoria, Australia. The reasons why B. mirabilis flowers freely but does not set seed were investigated.

Crop yield can be improved by minimizing plant-to-plant variability in seedling emergence. A study was conducted to determine the effect of variations in seed size and planting depth within a plot on emergence, proportion of infertile plants and grain yield in hard red spring wheat (Triticum aestivum L.). Large seed (40.8 mg kernel−1) was hand planted

Development of the male gametophyte of an infertile plant Armoracia rusticana Gaertn.
Plant Breeding, 2007AbstractHorseradish, Armoracia rusticana, is propagated vegetatively through root cuttings. It is described as a male‐sterile plant as it does not form seeds or only develops them in small quantities. This study discusses the anatomical structure of anthers and the events throughout meiosis up to the formation of a male gametophyte.

Relationship between species relative abundance and plant traits for an infertile habitat
Plant Ecology, 1998This study tested whether differences in species abundance at an infertile site could be explained by differences in the species' plant traits. Nine traits were chosen for the analysis based on results of previous studies conducted across soil fertility gradients. The traits were measured for each of seven herbaceous species whose abundance ranged from

Abstract Analysing a mathematical model, a previous study (Rodriguez, 1995) found that, when crosses between semelparous plants of different ploidy in deterministic environments produce inviable zygotes, the establishment of polyploids in communities where their deploid ancestors predominate is possible, when fecundity and selfing are high enough and

Sperm count distributions among exposed and control groups at a dibromochloropropane (DBCP) manufacturing plant were remarkably similar. Yet reproductive histories from 60 exposed men obtained in conjunction with the semen analyses indicated that fertility had been reduced during exposure. Ratios of observed to expected births or standardized fertility
