Fertilization And Embryo Development
Following ovulation, the egg is capable of fertilization for only 12 to 24 hours. Contact between the egg and sperm is random.
Once the egg arrives at a specific portion of the tube, called the ampullar-isthmic junction, it rests for another 30 hours. Fertilization sperm union with the egg occurs in this portion of the tube. The fertilized egg then begins a rapid descent to the uterus. The period of rest in the tube appears to be necessary for full development of the fertilized egg and for the uterus to prepare to receive the egg.
Defects in the fallopian tube may impair transport and increase the risk of a tubal pregnancy, also called ectopic pregnancy.
A membrane surrounding the egg, called the zona pellucida, has two major functions in fertilization. First, the zona pellucida contains sperm receptors that are specific for human sperm. Second, once penetrated by the sperm, the membrane becomes impermeable to penetration by other sperm.
Following penetration, a series of events set the stage for the first cell division. The single-cell embryo is called a zygote. Over the course of the next seven days, the human embryo undergoes multiple cell divisions in a process called mitosis. At the end of this transition period, the embryo becomes a mass of very organized cells, called a blastocyst. It’s now believed that as women get older, this process of early embryo development is increasingly impaired due to diminishing egg quality.
Why Does Ovulation Pain Occur
It’s unclear why only some women experience ovulation pain, or why exactly it happens. Some theories include:
- Spasming of the uterus or fallopian tubes as ovulation draws nearer
- The sensation of the egg itself bursting from its follicle, causing sharp pain
- Swelling of the follicle on the ovary that can cause a dull, achy feeling
Occasionally, a small amount of blood will be expelled from the ruptured ovarian follicle. The blood and fluid from the follicle are released into your pelvis during ovulation which can irritate the lining of your abdomen and cause discomfort.
Where Does The Egg Go After It Is Released From The Ovary
The Fallopian tubes, which connect to the uterus at the top, are typically thought of as the hallways from the ovaries to the uterusan egg, once released, is pulled in by the finger-like appendages at the end of the Fallopian tube, through which it travels down into the uterus over a period of 1224 hours.
When does one ovary produce a queen egg?
The Queen Egg continues to grow in preparation for her release around day 14. Each month, only one ovary develops a Queen Egg. (Typically, that is.
What happens to sperm at the time of ovulation?
However, in the case of unprotected sex around the time of ovulation, the Fallopian tube rises to its higher purpose: it becomes the venue for fertilization. Sperm actually have a surprisingly long journey toward the egg.

Is Ovulation The Only Time You Can Become Pregnant
No. While the egg can only be fertilized in the 12 to 24 hours after its released, sperm can live in the reproductive tract under ideal conditions for about 5 days. So, if you have sex in the days leading up to ovulation or on the day of ovulation itself, you may become pregnant.
If you are not trying to get pregnant, using contraception is your safest option, at all times of your cycle.
Understand Your Monthly Cycle
When you know your menstrual cycle, you improve your chances of getting pregnant. The first phase starts with the first day of bleeding during your period. Your body releases hormones, like follicle-stimulating hormone , that make the eggs inside your ovaries grow. Between days 2 and 14, those hormones also help thicken the lining of your uterus to get ready for a fertilized egg. This is called the follicular stage.

Tips For Relieving Ovulation Pain
Fortunately, there are several options available for relieving mid-cycle pain. These include:
- Use NSAIDs: Anti-inflammatory drugs, such as naproxen sodium or ibuprofen, may help lessen discomfort.
- Apply heat: Use a heating pad or warm cloth on your abdomen to help relieve the pain. You can try taking a warm bath too.
- Rest: Getting off your feet and relaxing can be useful in alleviating discomfort. Try lying in bed to lessen symptoms.
- Consider birth control: These pills can suppress ovulation.
While over-the-counter pain relievers are effective in relieving ovulation pain, some studies have suggested NSAIDs may negatively impact fertility. That said, women with endometriosis are more likely to experience severe ovulation pain, so it’s unclear in these cases whether it’s the health conditions or medications that are impacting fertility.
If you do prefer to take a pain reliever, acetaminophen has the least evidence of interfering with ovulation.
On Which Day Of Period Egg Is Released
Ovulation happens about 14 days before your period starts. If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14. If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.

How To Know When Youre Ovulating
Knowing when you ovulate can help you plan for sex at the right time and improve your chance of getting pregnant. You can keep track of your menstrual cycles on a chart, in a diary, or on a free period-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the first day you start bleeding . This is day 1. The last day of your cycle is the day before your next period begins.
Some people think the menstrual cycle and a period are the same thing.
A period is when you bleed .
A menstrual cycle starts on the day when a period starts and ends the day before the next period. A cycles length is considered normal if its between 21 and 35 days. They can vary between women and from one cycle to the next.
- Working out your average menstrual cycle length
If your menstrual cycles are different lengths you can work out your average cycle length.
The number of days in a womans menstrual cycle can vary month to month. Periods are not always regular. It can be useful to work out an average cycle length, based on the length of three menstrual cycles, to estimate when youre most likely to be ovulating.
If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.
Sarah tracked her last three menstrual cycles by counting the time from the first day of one period, to the day before the next period.
Cycle 1 was 28 days Cycle 2 was 32 days Cycle 3 was 27 days
28 + 32 + 27 = 87
When You Are Most Fertile
The 5 days before ovulation, together with the day you ovulate, are the days when you are most likely to conceive. Sperm can live up to 5 days inside your body, so if you have sex up to 5 days before your egg is released, you can get pregnant. After ovulation, though, your egg can only live for 12 to 24 hours. After this time is up, your time for getting pregnant has gone for now till the following month.
Your chances of getting pregnant are at their highest in the 3 days leading up to and including ovulation.

What Is The Difference Between Ovulation And Fertile Days
While an egg only survives for up to 24 hours, sperm can remain active for up to five days. It may therefore be surprising to learn that a couple can conceive through sexual intercourse four to five days before the egg is released.The total fertility window, taking into account the lifetime of both the sperm and the egg, is about six days. The are all the days during your menstrual cycle when you have the ability to become pregnant if you have unprotected sex.
Identification of additional fertile days provides couples with more flexibility to plan intercourse around their lifestyle and also more opportunities to conceive, which may reduce the pressure that couples can experience when trying to get pregnant.

Its A Complicated Process
However, sometimes a fertilized egg doesn’t make it to implantation.
For every 10 fertilized eggs, between 4 and 6 wonât make it to implantation .
These losses generally aren’t considered miscarriages, as most healthcare professionals consider a pregnancy to have begun at implantation. However, people who think or know they lost a fertilized egg may consider this to be akin to a more traditional miscarriage.
As you can see, thereâs a lot of steps in this process, and if any of them donât go exactly right, pregnancy may not occur. Sometimes, the egg attaches somewhere else, like to the fallopian tube, and the pregnancy will not be viable. This is called an ectopic pregnancy and should be treated as a medical emergency.
Although it can be complicated, it’s pretty amazing how often our bodies do get it right.

What Are The Chances Of Pregnancy After Rupture Of An Egg
The key to getting pregnant has to be understood through a womans ovulation cycle. In this article, we will understand the chances of pregnancy after egg rupture and how it works. Ovulation is a process where a mature egg is released from one of the ovaries, usually on or near the 14th day of a 28-day cycle. Nonetheless, the 14th day of this cycle counts as an average.
