If your work involves exposure to chemicals or toxins or a chance of injury, it's likely impacting your sperm health and future chances of conceiving a child.

Military work involves the possibility of combat-related injury and exposure to chemical warfare or toxins, both of which can negatively impact a male’s fertility or a couple’s pregnancy outcomes. A study of veterans of the US War on Terror found that rates of infertility were significantly higher—nearly twice as high—among veterans compared to civilians.
There are many chemicals, including endocrine disruptors and toxins, that can impact fertility and reproductive hormones. A brief, non-exhaustive list:
Mustard gas (sulfur mustard), associated with more than 4x the risk of male-factor infertility
Pesticides
Lead and other heavy metals
Microplastics and petrochemicals
Research shows that sperm-producing people who work in the agriculture, herbicides, construction, machinist, plastic production, printing industry, tobacco processing, and welding industries may see a negative impact on their fertility, including reduced sperm count and increased risk of miscarriage and birth defects.
Firefighters are at a higher risk of infertility than those who work in other professions. The scene of a fire may expose a person to a multitude of different chemicals, both in the burn and in the fire-suppressing foams (which typically contain PFAS). Exposure to PFAS is associated with decreased semen quality and reduced testosterone levels.
In addition, firefighters are at risk of increased scrotal temperature, either by being directly affected by the heat from fires or by heavy protective gear. Prolonged, increased heat around the scrotum can affect sperm production for months afterward.
The chances of conceiving with frozen sperm depend on several factors:
IUI pregnancy rates range from 10–25% per cycle; IVF success rates range from 5–50% per cycle. So, you may need multiple attempts to achieve pregnancy. The good news is that using frozen sperm doesn’t affect your chances of success. IUI and IVF pregnancy rates are the same for those using frozen sperm, compared to “fresh.”
Short answer: as many as you can afford. But the ideal number of samples to store also depends on your future plans. A few questions you might consider:
Do you have kids already? If you don’t, there may be a higher chance that you’ll want kids in the future, even if you’re sure you don’t want them right now. (Hence the vasectomy!)
How old are you? If you’re in your 20s or 30s, it’s more likely that your family plans may change in the future.
Generally speaking, one vial of sperm is used in each IUI or IVF procedure.
1 semen sample = 4 vials of frozen sperm
1 vial of frozen sperm = 1 IUI or IVF procedure
IUI pregnancy rates range from 10–25% per cycle; IVF success rates range from 5–50% per cycle. So, you may need multiple attempts to achieve pregnancy.
The process of sperm freezing is very quick with Legacy:
In theory, it can take as little as 3 days from start to finish. So, you don’t need to postpone your hormone therapy in order to accomplish your fertility preservation goals.
As long as sperm is kept frozen in a high quality cryogenic lab like Legacy’s, it can be stored indefinitely with no significant impact on its quality or the chances that it will result in a healthy pregnancy. That means you can keep your sperm frozen until you’re ready to start a family.
You can use your frozen sperm by transferring it to a healthcare provider or clinic for assisted reproductive methods such as IVF (in vitro fertilization) and IUI (intrauterine insemination). Transferring your sperm from Legacy to a provider is easy. You can start the process with a few clicks in your client dashboard.
We partner with several military-focused organizations to offer discounted and free services to members of the military and veterans. Learn more about Legacy’s military partnerships.
