Reproductive biology Reproductive biology Reproductive biology includes both sexual and asexual reproduction. Reproductive biology includes a wide number of fields: Human reproductive biology is primarily controlled through hormones, which send signals to the human reproductive structures to influence growth and maturation. These hormones are secreted by endocrine glands, and spread to different tissues in the human body. In humans, the pituitary gland synthesizes hormones used to control the activity of endocrine glands. Internal and external organs are included in the reproductive system. There are two reproductive systems including the male and female, which contain different organs from one another. These systems work
Endocrine disruptor to a lot of controversy due its potential estrogenic effect in humans. Tributyltin (TBT) are organotin compounds that for 40 years TBT was used as a biocide in anti-fouling paint, commonly known as bottom paint. TBT has been shown to impact invertebrate and vertebrate development, disrupting the endocrine system, resulting in masculinization, lower survival rates, as well as many health problems in mammals. Since being banned, the average human body burdens of DDT and PCB have been declining. Since their ban in 1972, the PCB body burden in 2009 is one-hundredth of what it was in the early 1980s. On
