Kan man bli gravid vid samlag före ägglossning eller på ägglossningsdagen?

Ja, det är helt möjligt att bli gravid genom samlag både före ägglossning och på ägglossningsdagen. Faktiskt är detta de dagar när chanserna att befruktning ska ske är störst.

Hur sker befruktningen?

För att graviditet shall occur måste spermier come into contact med an eggcell. Eggcellen released from ovaries during ovulation, som normalt occurs approximately 14 days before nästa mens starts.

Spermier kan överleva i kvinnans fortplantingsorgan i upp till fem dagar. Det betyder that spermier from a samlag several days före ägglossning kan fortfarande befrukta en eggcell när den släppes från ovariet.

When är chanserna störst?

Samlag under dagen leading up to ägglossning increases your chances of becoming pregnant, eftersom there then finns more spermier present when eggcellen släppes. Befruchtning probability is greatest if you have sex på ägglossningsdagen or the day before.

However, it is also possible to become pregnant if you have sex a few days before or after ägglossning, although the chance is lower. This is because both eggcells and spermier have limited lifespans – eggcellen can only be fertilized during approximately 12–24 hours after ovulation.

Factors affecting your chances

It is important to remember that many factors affect your possibility of becoming pregnant, including:

• Your age
• Your overall health and lifestyle
• How regularly you have sex
• Whether your menstrual cycle is regular or irregular

Advice for those trying to become pregnant

If you are trying to conceive, it may be worthwhile to identify your fertile window by following signs such as cervical mucus changes or using ovulation tests. For individual guidance and advice on how you can increase your chances of becoming pregnant, it is always best to talk to your doctor or midwife.
