Some of my ex-partners have pointed out that I produce very little semen compared to other men. Is that normal? If the problem is related to cystic fibrosis, as the disease progresses, will I stop producing semen and will this affect my orgasms? Are there any drugs that increase semen production?
Regarding your first question, that is, whether it is normal for a man with cystic fibrosis to produce less semen than other men, the answer is yes. Semen is made up of spermatozoa and fluid secreted by the testes. This fluid is transported in the vas deferens and, just before it is expelled, secretions from the seminal vesicles and prostate are added. We know that in 97% to 99% of men with cystic fibrosis, the vas deferens canals have either atrophied or disappeared, most likely because of obstruction in utero, so the important contribution of the testes is missing in these men. However, although they produce less semen, production is constant, and the quantity and quality of orgasms are not affected in any way. To my knowledge, there are no drugs for increasing semen production.
