Some men have asked me why we cannot use HCG solely to make our own testicles produce testosterone without the use of TRT along with it. Using HCG as sole testosterone replacement option may not bring the same subjective benefit on sexual function as pure testosterone delivery systems do—even when similar serum androgen levels are produced from comparable baseline values. However, supplementing the more “traditional” transdermal, or injected options, testosterone with the correct doses of HCG stabilizes blood levels, prevents testicular atrophy, helps rebalance expression of other hormones, and brings reports of greatly increased sense of well-being and libido. But in excess, HCG can cause acne, water retention, moodiness, and gynecomastia (breast enlargement in men).
Sperm parameters can vary quite a bit from test to test for a couple of reasons. 1. Abstinance period plays a big role. if you abstain 2 days for 1 test and 5 for the next, things might be pretty differnt. 2. small things in life — like heat — can cause pretty big swings in sperm. So a 1 time exposure to something can knock you down for a few days. 3. semen analysis vary quite a bit due to the level of care and skill of the technician performing them. In an absolute best case, you are looking at a 10-20% difference if the same sample was divided and run by 2 different people. So a count of 10 million could really be 8-12. When you add natural varience to varience in testing you can get some pretty big swings.
The skin of the penis is an ideal environment for bacteria to multiply, but the amount of bacteria depends on whether the man is circumcised or not. A study in the journal American Society for Microbiology found there were fewer kinds of bacteria on the penises of a group of men who got circumcised, compared to the samples taken when they were uncircumcised. The Centers for Disease Control and Prevention notes several studies found circumcision changes the bacteria ecology of the penis, which may explain why snipping the foreskin reduces the risk of HIV infection. The theory behind this is that anaerobic bacteria — bacteria that do not live or grow in the presence of oxygen — could cause the immune system to react in a way that makes cells more vulnerable to HIV infection in uncircumcised penises.
