Abstract

Male fertility is affected by quantity and quality of sperm which controlled by androgens (testosterone and 5α-dihydrotestosterone) mediated by androgen receptors (AR). Androgen receptors belong to receptor group of steroid hormone and a group of ligand-activated nuclear receptor superfamily. This paper explains androgen hormone and its regulation in spermatogenesis to increase male fertility. Regulation of androgen hormone in spermatogenesis include initiation of spermatogenesis, proliferation and maturation of Sertoli cells, germ cell development, spermatogonia, meiosis, and spermiogenesis. The role of androgen hormone in regulation of spermatogenesis is influenced by AR, luteinizing hormone (LH), and follicle stimulating hormone (FSH) levels. Disruption of spermatogenesis will cause low male fertility. However, low concentrations of AR, LH and FSH could be enhanced by exogenous gonadotrophine releasing hormone (GnRH), LH, FSH, and testosterone to increase male fertility.

Abstract

The article aims to explain Butonese women work ethics focusing on three factors, namely the development of work ethics, the aspects, and the challenges in developing their businesses. The research is a qualitative research with case study. The study is conducted in four villages in Luhu Hoamual District and West Seram District in Maluku Province, including Temi, Tapinalo, Mangge-mangge, and Eli. The informants were the Butonese women whose professions are traders. The methods used in this research are observation, interview and library research. The data analysis was done through reduction, presentation and concluding processes. This study found that the work ethic of Butonese women is not due to a religious calling as Weber said, but as a rational choice following Coleman ideas of surviving from the nature challenges, business opportunities, and family’s economic condition. In this process, two professions with different orientations were born. The pajibujibu sell their agricultural and plantation products from the west coast of Seram in Ambon city, meanwhile, the papalele sell fishery products on the west coast of Seram and the Hitu peninsula. If papalele is easy to get access to capital for business development, pajibujibu finds challenges to get it. Therefore, pajibujibu finds difficult to develop the business in compared to papalele. Nevertheless, both play important roles as actors in the economy of coastal communities.

Abstract

Lower conception rate of cows in the tropics might be affected by low quality of semen collected from bulls consumed low quality food. This study was conducted to evaluate the conception rate of Bali cows natural estrus inseminated with semen of the bulls supplemented with Moringa oleifera leaf (MOL) powder blocks. There were 51 Bali cows 3-4 years of age, non pregnant and having corpus luteum, used in this study. They were divided into 2 groups, group 0 (G0, n=23) were inseminated with commercially available semen. Group 1 (G1, n=28) were inseminated with semen of bulls supplemented with MOL powder blocks. All cows were artificially inseminated after natural estrus. Pregnancy diagnosis were perfomed by rectal palpation 60 days after the insemination. The mean diffents between the two treatments were analyzed by chi-squared analysis. Although statistical analysis showed that there was not different between the two treatments (P>0.05), but economically, the treatment of G1 could increase 10 % of conception rate. It can be concluded that the supplementation of MOL powder block could increase the conception rate of Bali cows natural estrus.
