Since sperm can only live for a maximum of 5 days in the female reproductive tract, only a small number of sperm will even survive the long journey through the female reproductive tract. Therefore, couples trying to conceive should plan to have intercourse a number of times in the days just prior to ovulation.
To do this means you must be able to predict when you will ovulate, a task that is sometimes more difficult than you might think. Fortunately, for those of us who need help, there are several reliable ways to predict when your most fertile days will occur during each cycle. In the first several days of the menstrual cycle called the follicular phase , certain hormones, specifically follicle stimulating hormone FSH , begin the maturation process of follicles the sacs that hold the egg in the ovaries.
In the second week of your cycle, FSH levels begin to decline and a single dominant follicle continues to develop. This growing follicle produces increasing amounts of estrogen, which initiates the ovulatory phase. Estrogen plays a key role in the ovulatory process and helps to prepare the body for pregnancy. This hormone helps build the lining of the endometrium, facilitates the secretion of fertile-quality cervical mucus which helps to protect and transport sperm through the reproductive tract and triggers the production of the luteinizing hormone LH.
By paying close attention to how your body responds to increased estrogen in the first couple weeks of your menstrual cycle, you can begin to predict ovulation. For example, many women know ovulation is just around the corner when they see an increase in production of fertile-quality cervical mucus.
Here is a brief introduction to some of the available tests and devices that can be used to help you pinpoint your fertility window. Error Include a valid email address.

Sperm that land on a dry surface would be lucky to last more than an hour. Additionally, our kits are insulated and extensively tested to ensure samples are not susceptible to sudden temperature changes in transit. These measures extend the lifespan of sperm outside the body to at least 48 hours, without significantly affecting the health of sperm.
Learn more about the science of at-home sperm testing. But while in storage, sperm quality is decreasing fairly rapidly. Studies indicate that DNA fragmentation and mitochondrial damage increase after 5 days of abstinence, and motility decreases as well after about 7 days.
A study examined the long-term effect of freezing on human sperm and pregnancy outcomes, looking at over , donor sperm samples. How long sperm live depends on where the sperm are deposited.
Sperm inside the vagina can live within cervical mucus or the upper genital tract for three to five days, allowing fertilization to occur so long as the sperm are living. This is why the fertile window is six days long — it includes the five days leading up to ovulation and the day of ovulation.
Once an egg is released, it is viable for 24 hours. Outside of the body, sperm can survive in semen for up to a few hours because they require precise conditions of warmth and humidity to survive.
