But when you take testosterone&nbsp;produced outside the body, the&nbsp;body&nbsp;will&nbsp;sense that testosterone levels have gone up. In response,&nbsp;the testicles will&nbsp;lower or stop&nbsp;sperm production.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you want to&nbsp;maintain&nbsp;your fertility and treat symptoms of low testosterone, work with your healthcare provider. There are some medicines that will not&nbsp;lower&nbsp;sperm production&nbsp;and may even help boost sperm counts.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-h-2-font-size\">What causes&nbsp;testosterone&nbsp;deficiency?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Testosterone naturally declines with age. In addition, some conditions can cause testosterone&nbsp;deficiency&nbsp;in&nbsp;people&nbsp;of all ages,&nbsp;including&nbsp;children.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some conditions affect the testicles\u00a0directly, leading to low levels of testosterone\u00a0(primary hypogonadism).\u00a0This can include inherited conditions, certain illnesses, injuries, and some cancer treatments.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With<strong>\u00a0<\/strong>secondary hypogonadism, testosterone\u00a0deficiency\u00a0is due to damage to the pituitary gland or hypothalamus, which\u00a0control\u00a0hormone production in the testicles.\u00a0This damage may be from inherited conditions, or happen from aging, being overweight, or medicines including opioids and anabolic steroids.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-h-2-font-size\">How is it diagnosed?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Typically, a&nbsp;diagnosis of&nbsp;testosterone&nbsp;deficiency&nbsp;depends on two&nbsp;things:&nbsp;&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Having&nbsp;signs&nbsp;of testosterone deficiency<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Low testosterone levels&nbsp;(below 300 ng\/dL)&nbsp;in&nbsp;a&nbsp;blood&nbsp;test&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Two separate blood tests&nbsp;are needed for confirmation. They&nbsp;should be done&nbsp;in the early morning on non-consecutive days. This is because testosterone levels&nbsp;are at their peak in the morning&nbsp;and change throughout the day.\u202f&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-h-2-font-size\">What are the treatment options?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In general, things that are good for your health&nbsp;(such as eating healthy foods and&nbsp;staying at a healthy weight)&nbsp;can help boost testosterone levels.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Certain foods that are rich in vitamin D and zinc can help boost testosterone. Some examples include fish, low-fat milk enriched with vitamin D, egg yolks, oysters and shellfish, and legumes.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However,&nbsp;diet&nbsp;alone is&nbsp;often&nbsp;not a cure for&nbsp;testosterone&nbsp;deficiency.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Medicine&nbsp;is often necessary, and it can come&nbsp;in&nbsp;many different forms, including&nbsp;injections,&nbsp;pills,&nbsp;skin gels\/patches,&nbsp;pellets&nbsp;implanted under the skin,&nbsp;and&nbsp;nasal gels.&nbsp;<strong>Almost&nbsp;all&nbsp;of these&nbsp;will&nbsp;lower&nbsp;sperm production&nbsp;(lower fertility).&nbsp;<\/strong>&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-h-2-font-size\">Who diagnoses&nbsp;and&nbsp;treats&nbsp;testosterone deficiency?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Many&nbsp;primary care physicians&nbsp;don\u2019t&nbsp;have specialized training&nbsp;for testosterone deficiency.&nbsp;They may not be familiar with all of the hormone medicines available, especially the fertility-friendly options.&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your best\u00a0option\u00a0is to see a\u00a0reproductive urologist<strong>\u00a0<\/strong>who specializes in testosterone deficiency and male infertility.\u00a0They\u2019ll work with you to understand your history and goals to find the right treatment path for you.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your Progyny Care Advocate&nbsp;is&nbsp;also&nbsp;here to help provide&nbsp;more information&nbsp;and answer questions you may have&nbsp;along the way.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Disclaimer:<\/strong>&nbsp;The information provided by Progyny is for educational purposes only and is not medical advice.
