Chemicals released during orgasm include
DHT
Acetylcholine
Dopamine
Serotonin
The overabsorbtion of serotonin in the brain leads to depression and anxiety as normal production of serotonin during the reward cycles of day to day activities have less of an impact on receptors compared to proportional serotonin release during orgasm.
Acetylcholine is directly linked to memory and concentration, and flooding the brain with it results in subsequent flushes. These flushes result in production of acetylcholine to make up for the deficit, and this cyclical production-flush interrupted by orgasm creates irregularities in otherwise regular cycles. Concentration and memory can be impaired by excessive masturbation.
