Ovulation is one of the most important times in the menstrual cycle, particularly if you're hoping to get pregnant. One of the most frequently asked questions in the course of discussions on fertility is: How many days egg live in the uterus after ovulation? It is important to know the duration of an egg's life and the path it takes through the reproductive tract to effectively schedule intercourse and maximise your chances of getting pregnant.
In this article, we examine the ovulation timeline, how long the egg stays in the body, and how long it is in the fallopian tube and uterus. We also examine the best timing for fertilisation and how that information can guide couples through their fertility journey.

Ovulation is the discharge of a ripe egg from the ovary. This happens at about the midpoint of the menstrual cycle, approximately 14 days before the start of the next period. The egg moves from the ovary into the fallopian tube once released, where it can be fertilised by sperm.
From this point, the next question most frequently posed is: How long does the egg stay in the fallopian tube?
The egg will stay in the fallopian tube for approximately 12 to 24 hours after ovulation. This is the time when fertilisation can happen. If sperm is already within the reproductive tract before ovulation or comes shortly afterwards, the probability of conception is greater.
It's well worth noting that sperm may remain alive in the female reproductive tract for as much as five days, more than double the life of the egg. For this reason, physicians tend to advise intercourse several days before ovulation to maximise timing.
If the egg is not fertilised within the 24 hours when it is in the fallopian tube, it will not survive when it reaches the uterus. Indeed, an unfertilised egg usually breaks down or gets reabsorbed by the body soon after 24 hours have passed.
So, when one queries how many days an egg survives in the uterus after ovulation, the simple truth is very few, if at all. The egg does not survive for days in the uterus if it is not fertilised. It either fails to get to the uterus or gets there already in the process of degeneration.
If the egg is encountered by a healthy sperm in the fallopian tube within its 12–24 hour lifespan, fertilisation is possible. The zygote formed makes its way towards the uterus. This process may take around 3 to 5 days. When it reaches the uterus, it tries to implant into the uterine lining, which signals the onset of pregnancy.
So while the unfertilised egg dies quickly, a fertilised egg has a much longer presence in the uterus, potentially turning into a successful pregnancy if implantation occurs.
If you’re trying to get pregnant, here are a few tips to keep in mind:
● Track Ovulation: Use ovulation prediction kits, monitor basal body temperature, or observe cervical mucus changes to identify your fertile window.
● Have Timed Intercourse: Because sperm may last longer than the egg, having intercourse 1–2 days before ovulation and on the day of ovulation is suggested.
● Understand the Egg's Duration: Keep in mind that the egg itself will only last 24 hours, so timing is everything.
● Don't Just Concentrate on the Uterus: As popularly misconceived, fertilisation does not occur in the uterus but rather in the fallopian tube, thus it is important to know for how long does the egg remain in the fallopian tube.
At Cloudnine Hospitals, we realise that the journey to parenthood is complicated with questions, feelings, and choices. If you are just starting to check your fertility or are going through assisted reproductive therapy like IUI or IVF, our experts at your side will guide you through it.
From hormone monitoring and ovulation tracking to cutting-edge fertility solutions, Cloudnine provides customised care aimed at increasing your probability of successful conception. We also educate you on every stage of your cycle—ranging from how many days an egg lives in the uterus to how many days it remains in the fallopian tube—so that you are more empowered and knowledgeable.
If you've been having trouble getting pregnant for more than a year (or six months if you're over 35), it might be time to see a fertility specialist. Consider the following signs as a sign to seek help:
● Irregular or missing periods
● Severe pain with menstruation
● Diagnosed reproductive health conditions, such as PCOS or endometriosis
● History of miscarriage
● Failure to conceive with timed intercourse
At Cloudnine, we provide thorough fertility evaluations and diagnostic tests to identify any underlying issues and customise the best solution for you.
Myth 1: The egg is alive in the uterus for a few days.
Reality: The egg can survive only 24 hours after ovulation. It won't live long in the uterus unless it gets fertilised.
Myth 2: Fertilisation occurs in the uterus.
Truth: Fertilisation is usually done in the fallopian tube, not the uterus.
Myth 3: If you do not have intercourse on the day of ovulation, you cannot become pregnant.
Truth: Sperm may survive up to five days, so having intercourse a few days before ovulation makes it possible to conceive.
To summarise, if you're wondering how many days an egg lives in the uterus after ovulation, the answer is quite brief. The egg has a lifespan of 12–24hours post-ovulation, mostly in the fallopian tube, not the uterus. If not fertilised, it breaks down quickly and does not survive in the uterus for more than a day.
Knowing the timing is vital for planning conception. Knowing how long the egg remains in the fallopian tube can guide you in having sex at the right time and help you conceive sooner.
At Cloudnine Hospitals, we provide the care, expertise, and support that you need to help you navigate each step of your fertility path. If you are planning naturally or thinking about fertility treatments, we are here to walk alongside you with kindness, transparency, and the best possible care.
