This paper examined the relationship existing between scrotal morphometric characteristics and reproductive potentials of rams. Reproductive organs have essential roles in the reproduction of species. Reproductive efficiency and increased production can only be achieved by understanding the morphometric characteristics of these very important and sensitive organs of reproduction. Sperm producti...

OBJECTIVE Concerns are growing about the decrease in male reproductive health. Caffeine is one of the popular nutrients that has been implicated as a risk factor for infertility. In the present study, we examined whether in utero and lactational exposure to caffeine affects the reproductive function of the offspring of rats. METHODS Pregnant rats received caffeine via drinking water during ge...

Studying the reproductive attributes of pests is central to understanding their life cycle history and in crafting management strategies to regulate, if not bring down, their population below threshold levels. In this article, the morphology of the male reproductive tract, topology of the spermatozoa, and salient features of spermiogenesis in the Chinese white pine beetle, Dendroctonus armandi ...

Two gonadotrophin releasing hormone (GnRH) constructs prepared by either chemical conjugation to keyhole limpet hemocyanin (GnRH-KLH) or as an expressed recombinant fusion protein (Multimer) were evaluated with or without adjuvants (immunostimulating complexes, ISCOMs, or cytosine-phosphate-guanosine oligodeoxynucleotides, CpG ODNs). After subcutaneous administration to Balb/c male mice at Week...

in order to examine the effect of the quantity of nitrogen fertilizer and bush density on vegetative and productive function of henna medicinal plant (lawsonia inermis)  factorial experimentation in the form of block plan was carried in three stages in agriculture research center in south of kerman  province in corp of 2012. the first factor containing nitrogen fertilizer in 4 levels including ...

This research aims to study testis and epididymis of dry land goat (Capra hircus) on B-mode ultrasound imaging. Twelve adult local male goats were examined normal testes ultrasonic appearances. real time scanner with a 7.5 MHz, linear array transducer was used evaluate the echotexture testicular parenchyma, mediastinum epididymis. The parenchyma represented uniformly homogenous moderately echog...

Auxin is an important regulator of many aspects of plant growth and development. During reproductive development, auxin specifies the site of flower initiation and subsequently regulates organ growth and patterning as well as later events that determine reproductive success. Underlying auxin action in plant tissues is its uneven distribution, resulting in groups of cells with high auxin levels ...
