How Contraceptive Monitors Make Your Birth Control Effortless
Although most people are unaware of the fact, fertilization and
conception can only occur during the 12 to 24 hours a women is
ovulation. Add to that the five days sperm can 'wait around' inside the
uterus for an egg to be released, and you have a short number of days,
often called 'the fertility window,' during which sex can lead to
pregnancy. Avoid sex or use a different method of contraption during the
fertility window and you have simple, natural birth control.
What stops more people from using this method? A big factor is
effort. Although studies have shown tracking your cycle can be an
extremely reliable method of birth control, the process of getting to
know the biological mechanisms taking place with in your body — and then
charting and graphing them — seems way too overwhelming.
This is where contraceptive monitors come in. Simply stated, they make natural birth control virtually effortless.
Persona: Introducing Test Stick Dependency
The
Persona monitor was the first mainstream contraceptive monitor to rely
on disposable urine test sticks to determine hormone levels. Hormones
levels in urine rise and fall indicating impending ovulation and when
ovulation has passed. When the urine sample stick is inserted into the
device, your fertility status is displayed with a green or red light.
Sixteen test sticks are used during the first ‘learning’ cycle', then
about eight sticks are used across eight days in future cycles. The
number of test sticks necessary may vary if there is a significant
variance in ovulation dates, or if ovulation is not identified. Persona
is said to have a 94% contraceptive reliability or a Pearl Index of six.
The Persona Brand is actually owned by THE mega pharmaceutical
company Procter and Gamble. They, of course, are looking to bring in big
money, so while the persona contraceptive monitor itself is quite
inexpensive, there is a catch. The continuous investment into test
strips, like ink cartridges for an ink jet printer, steadily increase
the actual amount you spend on the device.
Cost: £65 for the device. £14 a month for test sticks.
First 2 year cost: £401
Clearblue: The Upgraded Test Stick Monitor
The
Clearblue contraceptive monitor is basically the good old Persona in a
new shiny box with a very cool looking touch screen interface. It uses
the same Persona test urine test sticks, has the same quoted 94%
reliability, and even lights up with the Persona logo when it is turned
on.
In some countries, Clearblue is marketed as a fertility testing
device to aid conception, and in others it is marketed as a
contraceptive device. The same technology is used for both purposes.
This contraceptive device uses 2 x AA batteries which we are told
last for only 4-6 cycles due to having to power the touch screen, so the
cost of that should be factored in to the over all expense of the
computer
Cost: £99 for the device. £20 a month for test sticks (based on £40 for 20 sticks).
First 2 year cost: £579 plus batteries
The Old and New Lady-Comp a.k.a Baby-Comp
The
Lady-Comp a temperature only contraceptive monitor. It has been around
for about 25 years and uses BBT readings to identify ovulation. BBT is
taken with the integrated thermometer, and fertile and non fertile days
are calculated and displayed with red, green and yellow lights.
Readings are required every day and no extra fertility indicators can
be inputted. Its bright orange LED display can be seen in the dark,
although this drains a lot of power and a monthly charge is necessary.
A new Lady-Comp has been launched, also referred to as the Next
Generation Lady-Comp. We haven’t managed to get hold of a device yet but
we know it uses AAA batteries, therefore avoiding the need for the old
charger and the hassle of changing adapters during international travel.
It also now allows data to be transferred to a computer as opposed to
the old version where you needed to send the monitor in to receive a
print out back in the mail. The 99.3% quoted reliability suggests that
the internals of the Lady-Comp have not changed, but the user interface
has been upgraded.
Cost: £425 for the old Lady-Comp.
First 2 year cost: £425 plus batteries.
The Pearly: Cute and basic
Pearly,
is also produced by Valley Electronics, is touted as the mobile and
economical version of the Lady-Comp. It is defiantly smaller and cuter
than the original Lady-Comp which is quite cumbersome. The overall cost
of the pearly is still relatively high for this limited type of device.
The Pearly is a temperature only device, it requires daily BBT
readings throughout the cycle, and does not allow for any other
indicators to be imputed. It is quoted as having the same effectiveness
as the Lady-Comp, but can store less data and can't be downloaded
without mailing it in.
With the Next-Generation-LadyComp being launched we will have to see if the pearly continues to be offered.
An internal battery lasts for 2 years which can be sent in for exchanging with a small cost.
Cost: £290.
First 2 year cost: £290
Cyclotest: Effective, Affordable, Versatile.
Were not going to hide the fact that Cyclotest is our favorite contraceptive monitor. Here's a breakdown of why.
Sign up for an NFP course and they will teach you how to assess your
fertility using the Symptothermal Method. Modern medical professionals
insist that using just hormone tests or just temperature charts is not
as reliable as using more then one fertility indicator. The
Symptothermal Method, which uses both BBT alongside other indicators, is
the future of NFP. Cyclotest is the only monitor on the market that
allows, yet does not require, the to user to input cervical mucus
observations and LH test results. This small yet significant difference
blows all the other monitors out of the water.
Apart from increasing accuracy, using another indicator is important
if your sleep is disturbed resulting in a unreliable BBT reading. This
is especially critical around around the time of ovulation when an
inaccurate temperature reading could alter you projected fertility
window.
Cyclotest is also noteworthy because of the simple fact that it is
affordable. Many contraceptive monitors come with an astronomical price
tag, putting natural contraception out of the reach of the average
consumer. Cyclotest is reasonably priced, and even better, it does not
require test strips — so the low price remains low.
The low price however does not affect the functionality of the
monitor. It is 99% reliable, and the charts it produces can be
downloaded via USB. It has a flexible and highly accurate thermometer
and was awarded best fertility monitor by the German version of Which?
magazine.
Cost,: £149. £29 for the optional download software.
First 2 year cost: £149
Bioself: Retired With Honors
Bioself
was a very 1970s looking brown-beige device that was actually a pioneer
in contraceptive monitors. It used the very sound Symptothermal method
of charting fertility, had a quoted 99% reliability and included an
built in thermometer.
The downloaded charts were available via snail mail. Bioself was even
FDA approved, but sadly it never really took off in and production was
stopped.
The company ceased activities in mid 2013, although may still provide warranty support.
