Reproductive  health education should be given since early childhood by using language that is adapted to the stage of development. If you procrastinate and wait until the teenager it is already too late because in the days of the digital era, as now, all the information can be easily accessed by anyone including children early age. If the early childhood misinformed about their reproductive organs it would disrupt the physical and psychological development due to the wrong behavior in caring for and maintaining reproductive organs. Qur’an as the holy book of Muslims describes the steps of reproduction and  imparting education wisely as well as how to apply such education. This kind of education must be in accordance with the conditions of children and there should not be a lie about it We can also use media and methods such as pictures, songs, tap or other visual  media which can give clearer information, so that children can clearly see parts of the body, their characteristics, and how to treat and care them. The impropriate approach in conveying this kind of knowledge will be very dangerous for children. The provision of early age reproductive organs education can prevent the occurrence of deviant behavior as well as protect children from dangerous influence in early childhood development.

A preliminary research programme was carried out in order to study the acoustic wave reflection or target strength (TS) of tuna fish using a quantitative echo sounder (QES). The relationships between TS to fork length (FL) and swimbladder volume, for bigeye tuna (Thunnus obesus) and yellowfin tuna (T. albacares) are investigated. The TS of bigeye tuna was about 3 dB higher than yellowfin tuna when comparing species at the same size. The result can be correlated to the swimbladder volume differencebetween species. The relationship between TS and swimbladder volume was quantified for both species.Keywords: tuna fish, target strength, quantitative echo sounder

Reproductive health is a major problem that occurs in Indonesian adolescents. The problem is caused by some factors, including free sex that could induce reproductive organ diseases such as cervical cancer, ovarian cancer, vulvar cancer, uterine cancer, prostate cancer and sexually transmitted diseases. Incidence of various reproductive health problems is caused by a lack of knowledge about reproductive health. This issue needs to get attention from various parties, including teachers. However, some teachers are less understood about how to deliver reproductive health materials properly. This study aims to determine knowledge and attitudes of teacher candidates about reproductive biology. This study is a descriptive analytic study. The subjects were students of biology education at Jambi University who are in 5th and 7th semesters of academic year 2011/2012 (174 students).  The data was collected using tests and questionnaires. The results show that knowledge of the biology teacher candidates about the reproductive health is categorized as low (43​​%).  The attitude of biology teacher candidates about reproductive biology is classified as positive (64%). The formation of attitudes toward reproductive health is influenced by several factors including knowledge, experience, guidance from parents, social environment, mass media, cultural, and social institutions.

Abstract Comparisons across 13 inbred strains of laboratory mice for reproductive organ (paired seminal vesicles and paired testes) weights indicated a very marked contrast between the C57BL/6By and NZB/BINJ mice. Subsequently these strains were selected to perform a quantitative genetic analysis and full genome scan for seminal vesicle and testis weights. An F2 population was generated. The quantitative genetic analyses indicated that each was linked to several genes. Sixty-six short sequences for length polymorphism were used as markers in the wide genome scan strategy. For weight of paired testes, heritability was 82.3% of the total variance and five QTL contributed to 72.8% of the total variance. Three reached a highly significant threshold (>4.5) and were mapped on chromosome X (LOD score 9.11), chromosome 4 (LOD score 5.96), chromosome 10 (LOD score 5.81); two QTL were suggested: chromosome 13 (LOD score 3.10) and chromosome 18 (LOD score 2.80). Heritability for weight of seminal vesicles was 50.7%. One QTL was mapped on chromosome 4 (LOD score 9.21) and contributed to 24.2% of the total variance. The distance of this QTL to the centromere encompassed the distance of the QTL linked with testicular weight on chromosome 4, suggesting common genetic mechanisms as expected from correlations in the F2. Both testis and seminal vesicle weights were associated with a reduction in the NZB/BINJ when this strain carried the YNPAR from CBA/H whereas the YNPAR from NZB/BINJ in the CBA/H strain did not modify reproductive organ weights, indicating that the YNPAR interacts with the non-YNPAR genes. The effects generated by this chromosomal region were significant but small in size.
