When you’re trying to conceive, timing is everything. One of the most frequently asked — and incredibly important — questions is: How long does sperm live inside the uterus? For many couples on the road to parenthood, especially those facing male infertility, this answer can be the difference between frustration and fertility success.
At SCI IVF Hospital, a leading fertility clinic in Gurgaon, we understand how overwhelming the fertility journey can be. That’s why we’re here to help you understand your body better and use science-backed knowledge to improve your chances of conception.
So, How Long Does Sperm Live Inside the Uterus?
Under ideal conditions, sperm can survive in the female reproductive tract for up to 5 days. This might surprise you—especially when you consider how quickly other cells die once outside the body. But inside the uterus, things are different.
The uterus, when primed for conception (around ovulation), provides a nutrient-rich, protective environment that allows sperm to live longer. Timing intercourse during this fertile window greatly increases the odds of sperm meeting an egg.
The Role of Cervical Mucus
Cervical mucus plays a big role in this. During ovulation, it becomes thin, stretchy, and alkaline—ideal conditions for sperm survival. This “fertile mucus” essentially acts as a sperm superhighway, helping them travel safely from the cervix through the uterus and into the fallopian tubes.
What Is the Fertile Window?
Because sperm can survive up to 5 days and an egg lives about 24 hours after ovulation, there’s a 6-day window each month where pregnancy is most likely. These are the five days before ovulation and the day of ovulation itself.
Understanding your cycle and pinpointing ovulation can significantly boost your chances of getting pregnant naturally.
The Incredible Journey of Sperm
From ejaculation to fertilization, only a few sperm out of the millions released make it to the egg. They face acidic vaginal fluids, immune system defenses, and anatomical challenges. It’s truly survival of the fittest.
That’s why sperm health matters—a lot.
How Long Does Frozen Sperm Live?
If stored correctly in liquid nitrogen at around -196°C, frozen sperm can remain viable for decades. In fact, there are documented pregnancies from sperm stored for over 20 years!
Frozen sperm is especially helpful for:
-
Men undergoing cancer treatment
-
Couples dealing with male infertility
-
Donor sperm for IVF or IUI procedures
Even though motility may slightly decrease after thawing, treatments like ICSI (Intracytoplasmic Sperm Injection) at top fertility clinics in Gurgaon can still result in successful pregnancies using frozen sperm.
Factors That Affect How Long Sperm Survive
Several internal and external factors can influence sperm survival in the uterus:
-
Sperm quality: Strong, motile sperm live longer.
-
Cervical mucus: Fertile mucus improves lifespan.
-
Timing: Intercourse close to ovulation increases conception chances.
-
Health conditions: Infections or hormonal issues in the female reproductive tract can hinder sperm survival.
Male Infertility: A Common Concern
Male infertility is responsible for roughly half of all infertility cases. If you’re struggling to conceive after a year of trying (or six months if the woman is over 35), it’s worth getting a full fertility assessment.
At SCI IVF Hospital, our specialists conduct:
-
Semen analysis
-
Hormonal testing
-
Genetic screening (if necessary)
Even in cases of low sperm count or poor motility, modern technologies like IVF and ICSI make conception possible.

Skip the hot tubs and tight underwear—sperm like it cool

Consider sperm banking before cancer treatments
