What Are Gynandromorphs?

Hermaphroditism is the opposite of hermaphrodite . That is, a female and a male are obvious in an organism. Androgynous means that the animal has both sexes. Usually refers only to normal phenomena, and is different from phenomena such as intersex and hermaphrodite. Plants also have hermaphrodites.

The more complex the animal structure and the higher the evolution, the more distinct its distinctive characteristics become. Therefore, higher animals-animals with vertebrae-mostly belong to the former; animals with simple structures, low evolution, or degraded animals belong to the latter. This is a general rule. Because of this relationship, we must first start to observe the problems of the sexes in higher animals, and then inferior animals. Investigating to the extreme, even in higher animals, it is impossible to find a source of bisexuality, and humans cannot be listed as exceptions.

Gender homosexuality is also not a very simple property, which can be understood in a few words. It has various forms and various levels: some belong to the morphological aspect and some belong to the physiological aspect. Some of the hermaphrodites and the ovaries are independent and grow separately; some of the hermaphrodites do not have a separate testis and ovary; their sperm and eggs grow within the common gonad. This should not be called the testis (although sperm are produced) nor the ovary (although oocytes are produced), and the name is the male and female gonads or bisexual glands, which is most appropriate. Some androgynous animals, the sperm produced by their own testes and the ovum produced by their ovaries can combine with each other to perform auto-fertilization. In some bisexual animals, the autologous sperm and ovum cannot be combined with each other, or there is no chance of combining. Allogeneic mating has become a necessary condition for their seeding. In the past, some people pretended to be homosexual animals, and they did not ask for people; but in reality, this name can only be given to the former category, and not to the latter category ^[1]

Human trouble will be more

Humans can be even more troublesome, and scientists have found that mammals are generally affected by chemical pollution. Two-thirds of male Sitka black-tailed deer in Alaska were found to have cryptorchidism and staghorn growth abnormalities, and a similar number of white-tailed deer in Montana were also found to have genital malformations. In South Africa, antelopes found in chemically polluted environments have found damaged testicles. In a contaminated nature reserve, scientists have found that male spot rats no longer emit sperm.

On the other side of the earth, scientists have found androgynous polar bears, and about one in every 50 female bears has two sex organs. Sex-distorted animals are also found in the remaining male polar bears, which reduce the amount of sperm they emit. The length of the penis is shortened. A relatively small number of endangered animals, the Florida Black Panther, have also been found to have abnormal sperm.

Other studies have found that otter living in contaminated areas have smaller testes; marten penis exposed to PCBs is shorter. Beluga whales on the St. Lawrence River in Canada and killer whales on the northwest coast-two of the most heavily PCB-contaminated wildlife-have poor reproductive performance, and contaminated baby whales, seals and dolphins also show These characteristics. Scientists point out that this wealth of evidence is a serious warning for humans and wildlife. Charles, an expert in endocrine disorders at the University of Exeter. Professor Taylor said that the evidence in the report was the alarm bell and that all wildlife may be at risk because their gene pool will be reduced, making them less resistant to disease and facing dangers such as global warming .

Male decline sharply

Peter, the chief scientist of the Environmental Health Sciences, the world's most important authority on gender-distorted chemicals. "We found 100,000 chemicals that interfere with the hormone balance system, so it's not surprising that we also saw some serious conclusions. It has caused the fastest evolution in evolutionary history," Myers said. One of the most respected scholars, Lu of the University of Florida. Professor Gillet warned that the report waved "a big red flag" on humans. "If we see problems in wildlife, we should focus on similar issues with the proportion of men in humans," he said.

New research from the University of Rochester in New York shows that some newborn baby boys have high levels of phthalates. These babies are likely to have short penis and cryptorchidism. The distance between their anus and genitals is also short, and the shortening of the distance between the anus and the genitals is a typical sign of animal feminization. Research from the University of Rotterdam at Erasmus shows that baby boys born to pregnant women exposed to PCBs tend to play with dolls and tea sets rather than traditional boy toys when they grow up.

In many places, such as Canada, Russia, and Italy, which are heavily polluted by gender-distorted chemicals, the birth rate of girls is twice that of boys, which may provide a clue to the mysterious change in sex ratios worldwide. For the entire human race, the sex ratio at birth for men and women is 52:48; in other words, for every 100 girls born, 106 boys are born, but this ratio has become unbalanced. In the United States and Japan alone, there are 250,000 babies who were supposed to be boys, in fact girls.

Sperm counts are decreasing dramatically

Scientific research in more than 20 countries shows that the number of spermatozoa per milliliter of sperm fluid has dropped from 150 million to 60 million in the past 50 years-hamsters produce sperm nearly three times as much as 160 million. Neil at the University of Michigan. According to Professor Basu, this adds "very convincing evidence" to the effects of human sperm ^[1] .
