When planning the birth of a child, you need to know which days will be favorable for conception. This period is called ovulation, when the egg is mature and ready for fertilization. There are different ways to determine the ovulatory period. The simplest and most accessible is the application of the test. What systems are there, the best of them, and how much testing costs, is described in this review.
Content
The maturation of the egg falls on the 12-15th day of the cycle, it depends on its duration. Considering that most women have uneven cycles, it is impossible to guess on which day ovulation will move. In addition, stress, alcohol, exercise, antibiotics affect the female body.
The mature cell exits the ovaries into the fallopian tube to meet with the sperm. The possibility of conception depends on the life span of the egg, which is 12-24 hours. It is these two days that are optimal for fertilization.
The unfertilized germ cell loses its functions, dies off and is removed from the uterus along with exfoliating endometrial cells. Menstruation begins. The cycle is restarted.
Women may notice changes associated with ovulation. Sometimes they are expressed slightly, which makes it difficult to determine the fertile period.
Description of the signs of ovulation:
Ways to determine ovulation:
How do test systems work? The approach for all types is the same. They determine the level of chemicals in the analyzed sample: urine or saliva. Ovulation is regulated by luteinizing hormone (LH). Its level is determined using a reagent.
A high level means that the egg is ready. When a positive result is determined, it is advisable to have sexual intercourse no later than 48 hours, but not earlier than 2 hours after testing. This is due to the fact that diagnostic systems indicate the readiness of the release of the egg, and this takes time.
A low level of the hormone indicates that the egg is physiologically no longer capable of fertilization. The test result will be negative.
During pregnancy and menstruation, it is not advisable to diagnose.
From the frequency of use (single-use, reusable), the test material (urine, saliva) and other parameters, the following types of instruments are distinguished:
All research systems are medical devices, the production of which requires a registration certificate. It doesn't matter where you buy the tests: in online stores or pharmacies. With the help of the Internet, it is possible to control the issuance of permits for them.
How to choose the optimal combination in terms of cost and consumer characteristics is indicated below.
Disposable paper strip 2-3.5 mm wide, one end of which is treated with a reagent. It must be lowered into a container with urine no deeper than the designated border. The instruction indicates the dive time and waiting for the result. Until the result appears, the paper strip should be placed on a horizontal dry surface. If a second line appears on the test, the result is positive. The color intensity of the test strip is compared with the brightness of the control strip. If the test strip that appears is not sufficiently saturated, the peak of the LH surge will most likely occur the next day.
The release form can have a different number of testing tools. Typically a box of 1, 2 or 5 individually wrapped strips is offered.
It is disposable. It is used directly during urination, so urine collection is not required.The device has a fibrous rod that gradually fills with urine until it reaches the reagent. Before the result appears, it must be placed on a horizontal surface. Gives more accurate results than the strip test.
The general package usually offers 5 individually sealed strips.
One-time test, but allows the study to be carried out several times. It is a plastic case with special windows for each examination procedure. Inside is paper with reagent. A few drops of urine are applied to the cell. After a certain time, according to the instructions, the result appears. One strip in the window is control, the second is a test, which shows a positive result. Usually intended for 1, 5 or 10 uses.
Reusable device. But disposable replaceable strips are inserted inside it. The digital method got its name because it converts information into digital form and reflects it on the display.
How to do the research is detailed in the instructions. The test strip must be charged before use. The device closes with a click. Testing should begin after the ready-to-work indicator turns on.The tip of the test, on which the strip with the reagent is fixed, is placed inside the container with urine for a time determined by the instructions. Then it must be left on a flat horizontal surface until the results appear. If the result is positive, a smiley will appear on the display, if the result is negative, an empty circle will appear.
The kit contains a diagnostic device and replacement strips. Mostly their number is 7.
Reusable high-tech device. Externally designed, like a lipstick or powder box. In fact, it is a mini-microscope or a miniature biochemical analyzer for the study of saliva. The device operates on batteries. Some types of electronic devices need to be pre-ordered online.
You need to use the test within 5 days of the expected ovulation period, i.e. in the middle of a cycle. This period may be shortened after observing several cycles.
Testing is carried out in the morning and in the evening to obtain up-to-date information. Favorable time - from 10:00 am. until 20:00 h. This is the period when the main production of luteinizing hormone occurs.
Doctors give advice 3-4 hours before testing not to drink a lot of water, because. this can reduce the concentration of LH in the urine.
