When is ovulation ?

Knowing when ovulation means that you know when your fertile time of the month is. The fertilisation window each month is actually quite small for women. If you are going to conceive, it is within 24 hours after ovulation.

Ovulation usually occurs approximately 14 days before your period is due ie the 2nd stage of the menstrual cycle (the luteal phase) is usually 14 days long. This is fixed for most women although it can vary between 11-16 days for some. The part of the cycle that more often varies is the first half ie the run up to ovulation or the follicular phase.

If your follicular phase is the same each month this makes knowing when ovulation occurs very easy and predictable using a calender. The problem occurs when the folicular phase of your cycle is erratic or unpredictable. Irregularity of the pre-ovulation phase are more common in young women under 25 years & in older women (over 40 years) often being shorter or longer and less predictable.

For some women the follicular phase can be very prolonged for example in polycystic ovarian syndrome or the cycle may be anovulatory (ie ovulation does not occur)

If the cycle is irregular ovulation predictor kits can be helpful if you are trying to conceive.

What is ovulation ?

Ovulation is the term used for the release of a viable egg from the ovary.

Conception can not occur until the viable egg is released, and starts its journey down the fallopian tube towards the uterus.

The trigger for ovulation to occur is a sudden increase in the blood levels of the hormone LH, released from the pituitary gland. Normally the egg is released 14 days before the 1st day of the next menstrual period is due to occur. If conception and implantation occurs the period does not occur and an early pregnancy is progressing.

It is possible to measure LH in urine using ovulation prediction tests

LH levels in blood can also be tested by hospital tests, normally on day 19 of the cycle.

FAQ-When is the best time to do a urine ovulation LH test ?

Determining the best time to collect your urine for LH testing 

For best results, collect your urine at about the same time each day, for example, between 10:00AM and 8:00PM. Some women have found that their best specimen is after 12 noon.

Do not collect your first urine after waking up.  Reduce your liquid intake approximately 2 hours prior to urine collection. 

You can store your urine for later testing in the day. Your urine can be stored at room temperature for up to 8 hours or in the refrigerator for up to 24 hours. Do not freeze it.

For best results, test your urine on the same day that it is collected. If you refrigerate your urine, let it reach room temperature before testing (about 30 minutes). Do not shake the container. If a sediment forms at the bottom of the collection container, allow the sediment to settle. Use only urine from the top of the container.

FAQ-What exactly is ovulation & how do urine LH ovulation tests work ?

 Access Diagnostics fertility

Thought it may be helpful to some readers to run over the basics of ovulation and when the most fertilie time occurs.

Ovulation is the release of an egg from the ovary. The egg then passes into the fallopian tube where it is ready to be fertilised. In order for pregnancy to occur, the egg must be fertilized by sperm within 24 hours after its release.

Immediately prior to ovulation , the body produces a large amount of luteinizing hormone (LH) ,which triggers the release of the ripe egg from the ovary.

This LH surge usuallly takes place in the middle of the menstrual cycle.

Ovulation Prediction Tests help you to predict the time of ovulation & therefore peak fertility.

It is during this fertile time that pregnancy is most likely to occur.

The ovulation prediction test detects the LH surge in urine, signalling that ovulation is likely to occur in the next 24-36 hours
