Step 1: Understanding the Concept: 
The question asks to identify a hormone that is the "same" in both men and women. This can be interpreted as being present in similar quantities or having identical primary roles, which is not the case for sex hormones. 
Step 2: Detailed Explanation: 
- Progesterone and Oestrogen are primary female sex hormones but are also present in small amounts in men. 
- Testosterone is the primary male sex hormone but is also present in small amounts in women. 
- All three listed hormones are present in both sexes, but their concentrations and primary functions are vastly different between men and women. They are not "the same" in any practical sense. Many other hormones not listed here, such as insulin, thyroxine, cortisol, and adrenaline, are indeed the same and function similarly in both sexes. Since these are not options, and the listed sex hormones have very different profiles in men and women, the most accurate answer is 'None of these'. 
Step 3: Final Answer: 
While Progesterone, Testosterone, and Oestrogen are found in both men and women, their levels and primary roles are significantly different. Therefore, none of them can be considered "the same" in both sexes.
