All adults have some amount of both estrogen and testosterone. Having too much or too little of either can cause problems.
I think Hall's thoughts about the differences between men and women are a major stretch. She went from being a woman with a lifelong testosterone deficiency, to being a woman with normal levels from the treatment. Saying "men play life on easy" from that experience is a big leap to conclude from finding that's poker is easier after getting treatment.
Most activities become easier after getting treatment for a lifelong health issue. I experienced similar improvements in my field from reducing my T levels by about 90%. Can't reasonably conclude anything about gender from that. I can say, disorders suck, and effective treatments are pretty nice.
If you think low T is likely an issue, by all means get a blood test. Hormone levels are quite simple to check.
