During a phalloplasty, the surgeon performs a vaginectomy and lengthens the urethra to allow for urination through the penis. Disadvantages of a phalloplasty include the number of surgical visits and revisions that may be necessary, as well as the cost, which is typically higher than that of a metoidioplasty. A person may decide to have a scrotoplasty — the creation of a scrotum — alongside a metoidioplasty or phalloplasty. In a scrotoplasty, a surgeon hollows out and repositions the labia majora to form a scrotum and inserts silicone testicular implants.
For example, smoking slows down recovery and increases the risk of complications following surgery. If a person smokes, vapes, or uses any substance with nicotine, a medical team may consider them less eligible for this type of surgery.
Following gender-affirming surgery, most people need to stay in the hospital for at least a couple of days. After leaving the hospital, the person needs to rest and only engage in very limited activities for about 6 weeks or longer. A person who undergoes a metoidioplasty may have erections and enjoy more sensation in their neopenis. However, the penis will be relatively small in size.
A neopenis that results from a phalloplasty is usually larger, though it may be less sensitive. To have erections, a person will need a penile implant.
If a person has urethral extension, the goal is to be able to urinate while standing after a full recovery from the procedure. Some studies report a high number of urological complications following phalloplasties. It is important to attend regular follow-ups with a urologist. Transgender men tended to report more frequent masturbation, sexual satisfaction, and sexual excitement than transgender women. Environmental, social and behavioral factors also influence hormones in both males and females, complicating the idea that hormones determine sex.
Progesterone changes in response to typically male-coded social situations that involve dominance and competition. Though testosterone levels are different between males and females on average, many external factors can change these levels, such as whether or not a person is raising a child.
Differing testosterone levels in both men and women can predict certain parenting behaviors. Even the content of a sexual fantasy can change testosterone levels. The fact is, behavior and environment—like cultural gender norms and expectations—influence sex-related hormones, and the biology of the body and brain itself.
While this is a small overview, the science is clear and conclusive: sex is not binary, transgender people are real. It is time that we acknowledge this. The trans experience provides essential insights into the science of sex and scientifically demonstrates that uncommon and atypical phenomena are vital for a successful living system. Even the scientific endeavor itself is quantifiably better when it is more inclusive and diverse.
So, no matter what a pundit, politician or internet troll may say, trans people are an indispensable part of our living reality. Transgender humans represent the complexity and diversity that are fundamental features of life, evolution and nature itself. That is a fact. It originally referred to participants as transgender. The views expressed are those of the author s and are not necessarily those of Scientific American.

Human sexual reproduction proceeds through the combination of sex cells of two different sizes, small gametes sperm and large gametes ova. Researchers across many disciplines take this as foundational to their work. Transwomen who have had sex reassignment surgery will lose the ability to produce small gametes, because such surgery removes their testicles, but they do not gain the ability to produce large gametes, because sex reassignment surgery cannot give them ovaries.
A male person could get testicular cancer and have to have his testicles removed. Sure, some people have penises and some people have vulvas, but this is no more significant than the fact that some people are fat and some are skinny.
This definition vindicates change of sex; you get it whenever you get a change in gender identity. This is at best a nuisance, because the replaced category have to develop a new term and fight for new legal rights to protect it, and at worst an injustice, because it erases a significant axis of oppression and precludes its mitigation.
The four primary sex characteristics are: external genitalia; internal genitalia; gonads; and chromosomes. For a male person these are penis and scrotum external genitalia , urethra and prostate internal genitalia , testes gonads , and XY chromosomes. There are many options for transitioning, including medical and nonmedical options.
Some transgender people in transition get surgery, some get hormone therapy, and some get a combination of both. These options may also include counseling. Many transgender people transition without using hormones or surgery.
Nonmedical options include:. Children form their gender identity early. Most children believe firmly by the age of 3 that they are either a girl or a boy. The feeling that they are different may start early in life. Many transgender adults remember feeling a difference between their bodies and what they felt inside at a young age.
Others didn't feel this way until later in life. Children and teens grow and develop quickly. Sometimes before and during puberty, they may feel more like one gender some of the time, and more like another gender at other times. That's why it's important to explore nonmedical or reversible options, such as allowing your child to live as their identity.
They may want to wear the clothes of their gender identity, use a different name, or ask others to use a different pronoun. You can also talk to your child's doctor about types of reversible hormone therapies that can help your transgender child to transition.
