5. iFertracker – Smart Fertility Tracker

The iFertracker is one of the first overnight basal body temperature (BBT) trackers. It measures BBT by placing the device under armpit during the night. It has a very slick white design and comes with a smart app which automatically records data, charts BBT trends and tracks physiological responses and movements. Customers have left mixed reviews about iFertracker. Many customers complained about its short battery lifespan which lasts only 5 days and sometimes dies in the middle of the night, making the recorded BBT impossible to retrieve. On the other side, small size and light and lightweight is something that makes this product convenient. Considering iFertracker’s low price tag, it might be worth giving it a shot if you’re low on budget.

How does pregnancy work?

If you are a sentient human being you’re probably somewhat aware of how babies are made. Plus if you’re looking at our fertility monitor reviews, you might even be trying to get pregnant yourself. Most people are aware that when a man meets a woman, and they feel attracted and have sex, nine months later a baby is born.

However, there is a lot more to this process than meets the eye. Fertility originates in the woman’s ovaries. The ovaries are two glands shaped like almonds that are attached to the uterus. When a woman is born, she has between 1 to 2 million eggs.

Right from the get-go, the eggs will begin dying off- women do not produce any more eggs throughout their lifetime. A woman likely will release around 400 eggs during her reproductive years. The reproductive years begin when she first has a period and then and with menopause. For most women, menopause occurs between the ages of 45 and 55. During ovulation, a woman’s egg will live for roughly 24 hours.

She has to be fertilized quickly for conception to actually occur. In the event that her egg connects with a man’s sperm during its travel to the uterus, the sperm and egg unite and conception occurs. If pregnancy does not occur then the woman’s ovaries will cease producing progesterone and estrogen. The uterine lining will be shed during the subsequent period.

How does a sperm reach the egg?

After you have had sex with your partner, there isn’t much you can do to facilitate or increase the chances of conception. Some health professionals claim that if a woman lies on her back with her buttocks elevated for between 20 to 30 minutes then gravity can aid the sperm’s travel to the egg.

Other than that, you and your partner will just have to let nature take its course. A variety of complex biological processes are underway. So sit back, watch some TV, catch up on Netflix, and let nature work its magic. The sperm is on a long journey. Millions of sperm are navigating the insides of the woman.

The first battle that they confront is the acids in the vagina. These can kill sperm. Cervical mucus can create an impassable frontier as well. When a woman is most fertile is when the cervical mucus actually clears, and it then allows the strong sperm deeper access.

Even at that point, they are still many difficulties ahead. The sperm is required to traverse about 7 inches- traveling from the cervix to the uterus and then on to the fallopian tubes.

If they are unable to locate an egg inside of the woman’s fallopian tubes, the sperm can actually exist inside of this reproductive tract on average for between 3 to 5 days. The odds of sperm actually reaching an egg are incredibly low. Only a few sperms will ever actually achieve access to it.

The other sperm dies along this journey. For the sperm that actually gets near the egg, they still must penetrate its outer shell and then reach its insides before its competitors do. Once sperm has entered the egg, the egg actually instantaneously changes, disallowing any other sperm from accessing its insides. The egg will then be fertilized within around 24 hours.

The genetic content of the sperm and the egg merge to create a new cell that then begins rapidly dividing. The new cells are then known as the embryo- you are not actually pregnant until this bundle will then travel down the fallopian tubes attaching to the uterine wall.

In rare cases, it will attach to something other than the uterus. This is called ectopic pregnancy. These are not viable pregnancies and a medical intervention is required to keep it from growing.
