Some ignorant people try to tell us that s*x is simple: XX means female, XY means male. But biology has shown us, again and again, that reality is much more complex. Here's a brief explanation:
In 1890, scientists discovered the X and Y chromosomes.
Testing showed that most men had 46 chromosomes, including one X and one Y, while most women had 46 chromosomes with two X’s.
The natural conclusion: the Y chromosome defines maleness.

By mid-20th century, it became clear that some men had 47 chromosomes (XXY), and some women had 45 (a single X). The model still held: the Y chromosome was seen as the defining factor.
Then research revealed that not all men were 46,XY — in fact, about 1 in 300 weren’t. And some women had XY chromosomes. So the neat picture began to break down.
+
After DNA’s discovery, researchers pinpointed the SrY gene on the Y chromosome as the critical switch. But sometimes the SrY gene was missing, or even translocated to another chromosome. This led to 46,XX men and 46,XY women.
The situation grew even more complicated:
Some people had XY chromosomes but developed as female due to Androgen Insensitivity Syndrome.
Others with XX chromosomes were masculinized by Conge***al Adrenal Hyperplasia.
In the 1970s, conditions like 5-alpha-reductase-2 deficiency were identified. In certain populations (such as villages in the Dominican Republic), about 1 in 50 children appeared female at birth but developed male characteristics at puberty ("guevedoces").
+
By the 1990s, scientists also discovered that hormone fluctuations in the womb could cause body parts to develop along different s*x pathways, regardless of genetic makeup.
Studies on brain structure refined this picture further. For example, research showed that male-to-female trans women had neuron counts in a limbic nucleus consistent with typical female patterns (Kruijver et al., 2000). In other words, ge***al s*x and brain s*x can diverge.
+
S*x differentiation is not a tidy binary. It is a complex, timing-dependent process during fetal development, and multiple biological systems (chromosomal, genetic, hormonal, neurological) interact in different ways.
Treating “XX = female / XY = male” as an absolute truth works as a basic rule — the way Newtonian physics works for everyday life. But just as Einstein’s relativity is necessary to explain extremes (the very big, small, or fast), the simplified chromosome model breaks down when we look at inters*x and trans realities.
+
Inters*x conditions are real. Trans people are real. Neither category implies mental illness.
Scientific reality shows that s*x and gender do not reduce to chromosomes — legislation cannot erase that, any more than declaring “Pi = 3” would change mathematics.
The takeaway: People don’t need “fixing” for existing outside binary rules. Biology itself proves it: diversity of s*x and gender is natural.
