If you value your erections, perhaps try some lifestyle modification.
Most men are 46 XY. Rarely--or perhaps not so rarely--one out of 1000 baby boys have an extra-X chromosome. Their karyotypes, as seen above, are 47XXY.
These boys, most often, have totally normal appearances and grow up to be totally healthy men with normal male characteristics. Their only abnormalities are that they have very small testicles that do not produce sperm. These men are infertile.
While in the past these men were considered hopelessly infertile, now, due to advances in sperm detection procedures, fertility preservation, and assisted reproductive technologies, some of these men can now father their own biological children.
Finding sperm in a testis can be challenging. Several strategies exist, some more invasive (microTESE) and some less invasive (the TFNA mapping). I have adopted the TFNA mapping protocol because it is well tolerated and with very little risk of testis damage, it is also effective in locating pockets of sperm production within the testis, like findings apples on a branch. TFNA mapping provides a detailed "map" to tell me where to go to find the sperm when I do the actual sperm retrieval--the TESE.
Some cancers happen most often in people of reproductive age. Having cancer at any age is terrible but at young ages it is particularly awful. Not only do young cancer patients worry about surviving, they must also worry about long term problems from cancer treatments. One common problem is infertility post cancer therapy.
Most medical oncologists are well aware of post-cancer treatment infertility yet often do not refer patients for fertility preservation treatments such as sperm banking. Some reasons for the disconnect between knowledge of fertility preservation technologies and referral for them include price, inconvenience, time considerations, patient preference, and others.
Sperm banking is actually readily available in most communities, is not particularly expensive, and can have a tremendous impact on the future life of a young cancer survivor.
