An abnormal sperm count may also indicate an underlying health condition. A normal sperm count ranges from 15 million sperm to more than million sperm per milliliter mL of semen. Anything less than 15 million sperm per milliliter, or 39 million sperm per ejaculate, is considered low. A low sperm count is often referred to as oligospermia. A high, or above average, sperm count is over million sperm per millimeter.

Low sperm count means that the fluid semen you ejaculate during an orgasm contains fewer sperm than normal. A low sperm count is also called oligospermia ol-ih-go-SPUR-me-uh. A complete absence of sperm is called azoospermia. Your sperm count is considered lower than normal if you have fewer than 15 million sperm per milliliter of semen. Having a low sperm count decreases the odds that one of your sperm will fertilize your partner's egg, resulting in pregnancy. Nonetheless, many men who have a low sperm count are still able to father a child. The main sign of low sperm count is the inability to conceive a child.

Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении. - Коммандер, - все же возразила она, - это слишком крупная неприятность, и с ней не стоит оставаться наедине.

И все же… секрет Цифровой крепости будет служить Хейлу единственной гарантией, и он, быть может, будет вести себя благоразумно. Как бы там ни было, Стратмор знал, что Хейла можно будет всегда ликвидировать в случае необходимости. - Решайтесь, приятель! - с издевкой в голосе сказал Хейл.  - Мы уходим или нет? - Его руки клещами сжимали горло Сьюзан.

Беккер посмотрел на него с недоумением. Панк сплюнул в проход, явно раздраженный невежеством собеседника. - Табу Иуда.
