A deficiency in semen is the most common cause of male infertility. MATERIALS AND METHODS The study included 180 male subjects aged 18-50 years with 26 fertile and 154 infertile. The infertile subjects were further subdivided a...

Fertility reduction due to sub-fertile males is a major concern in breeder flocks. Phenotypic traits of broiler breeder males and their relationships with fertility can be used as reliable indicators for identification and removal of sub-fertile males from the breeder flocks. This study was conducted to investigate semen traits (semen volume, sperm motility, sperm viability and sperm count) and...

Partial male-sterile (ms(4)/ms(4)) soybeans (Glycine max L. Merr.) and their fertile isoline (Ms(4)/Ms(4)) were grown in adjoining field plots. From 62 until 92 days after emergence, the nitrogenase activity, assayed by acetylene reduction, of the average male-sterile plant was approximately twice that of the average fertile plant. At approximately 100 days after emergence, the assayable nitrog...
