Reviewed by Image Credit:linda_kar/Shutterstock.com Sex hormones are also known as sex steroids, gonadal steroids, and gonadocorticoids. These are steroid-based hormones that interact with vertebrate steroid hormone receptors. Sex hormones principally exert their effects to produce sexual differentiation and reproduction. In females, the ovary produces three classes of sex steroids. These include estrogens, progestins, and androgens. The effects of these three sacks hormones are mediated by slow rate genomic mechanisms acting through nuclear receptors and non-genomic mechanisms through membrane-associated receptors to elicit several signaling cascades in a fast response. The polypeptide hormones luteinizing hormone, follicle-stimulating hormone, and gonadotrophin-releasing hormone are associated with the sex hormones and can produce sex-regulated responses but are not regarded as sex hormones themselves. The gonads produce sex hormones, that is, the ovaries or the testes alongside the adrenal glands. Alternatively, they are produced due to the bioch...

As a clinical geneticist, Paul James is accustomed to discussing some of the most delicate issues with his patients. But in early 2010, he found himself having a particularly awkward conversation about sex. A 46-year-old pregnant woman had visited his clinic at the Royal Melbourne Hospital in Australia to hear the results of an amniocentesis test to screen her baby's chromosomes for abnormalities. The baby was fine—but follow-up tests had revealed something astonishing about the mother. Her body was built of cells from two individuals, probably from twin embryos that had merged in her own mother's womb. And there was more. One set of cells carried two X chromosomes, the complement that typically makes a person female; the other had an X and a Y. Halfway through her fifth decade and pregnant with her third child, the woman learned for the first time that a large part of her body was chromosomally male. “That's kind of science-fiction material for someone who just came in for an amniocentesis,” says James. Sex can be much more complicated than it at first seems. According to the simple scenario, the presence or absence of a Y chromosome is what counts: with it, you are male, and without it, you are female. But doctors have long known that some people straddle the boundary—their sex chromosomes say one thing, but their gonads (ovaries or testes) or sexual anatomy say another. Parents of children with these kinds of conditions—known as intersex conditions, or differences or di...

Stereotyping is a necessary evil. Stereotyping simplifies complex information so our brains can easily understand it, reducing the amount of processing we go through when seeing or meeting new people That said, it also causes us to generalize. If we see one hipster drinking PBR and wearing an “Everyone loves Grandpa!” T-shirt, our brain is like, #YesAllHipsters. When it comes to lesbians, I was curious if the stereotypes had a basis in reality, partly because I am a former gym teacher who drives a truck and loves cats and has a wardrobe that’s 90 percent flannel. I've probed the data to see if the old lines about U-Hauling, lesbian bed death and others had any statistical sway. The results were surprising. 1. U-Hauling. The most common lesbian joke is often attributed to comedian Lea Delaria, who once remarked: “What does a lesbian bring on a second date? A U-Haul.” This plays into the notion that queer women tend to move in together at lightning-fast speeds. While there are no significant statistics comparing the cohabitation speeds of queer vs. straight women, there is some science that pinpoints why a lesbian couple might move in together sooner than a hetero couple. Some of these reasons have to do with societal norms, financial benefits and hormones. “U-hauling happens for two reasons,” explains clinical psychologist Lauren Costine at And we all know what happens when you leave oxytocin floating around: trips to Bed, Bath and Beyond. 2. Processing. Another oft-recited...

Sexual trait (Sexual characteristic): A body part or characteristic that differs based on biological sex. Primary sexual traits are present at birth. They include body parts on the inside and outside of the body that are essential for reproduction. Secondary sexual characteristics are body parts that appear later. Secondary sex traits, such as facial hair, are not required to produce offspring. You go to a restaurant and look over the menu. Burgers, pizzas, tacos––it all sounds so good! Finally, the waiter comes around and it’s time to place an order: pizza it is.You tell the waiter your order, and they take it back to the kitchen and tell the cook. Once the cook knows what food you want, they can start making your pizza. Messengers can help make things run smoothly, whether in a restaurant where you're ordering pizza, or in the human body.Image by Aline Ponce via Pixbay. Wouldn’t it be easier if you just told the cook what you want yourself? Not really. The cook has lots of food to make, and not enough time to leave the kitchen or talk to every customer. That’s why the restaurant needs a specific messenger (the waiter) telling the cook what customers want. Our cells also use messengers, called hormones, to talk to each other. Hormones are like messengers that travel to different cells and tell them what to do. Hormones attach, or bind, to the outside of certain cells to deliver their message. The cell that receives the message will then change what it’s doing based on the...

Hormones which constitute the secondary sexual characters are called sex hormones. In general, hormones work instantly when they released in blood stream. Sex hormones are different because they start to work later on. They gradually prepare in the body for reproduction. The sex hormones are responsible for the fundamental change in growth & development and stimulate the developments of secondary sexual characters. The testes and the ovaries are the reproductive Organs and both are stimulated by the pituitary hormone during Puberty. That’s the reason these are called sex hormones. Functions of Sex Hormones: • In male, the testes produces the male sex hormone testosterone. This hormone helps in the development and maintenance of the primary and secondary sexual characters and production of sperms. • In female, the ovaries secrete oestrogen and progesterone responsible for the primary and secondary sexual characters.
