I am Sun Yi and everyone calls me Jojo.
I am a master of medicine, an attending doctor of obstetrics and gynecology in Shanghai 3A Hospital, a member of the Popular Science Group of Obstetrics and Gynecology of Shanghai Women’s Rehabilitation Medical Association, and a multi-platform We Media native. I am committed to sharing popular science knowledge on women’s health.
Many friends have plans to prepare for pregnancy, but they know very little about common sense of childbirth.
Jojo, a best friend of obstetricians and gynecologists, first gave everyone a wave of Amway, which only professional obstetricians and gynecologists know about fertility.
5 Little Knowledge of Fertility
1. The number of mature eggs that a girl can have in her whole life is already destined at birth, about 400 ~ 500.
2. Women’s fertility is inversely proportional to their age. With the increase of age, fertility will slowly decline. The peak of fertility is around 20-28 years old. After 32 years old, women’s fertility will slowly decline, and after 37 years old, it will rapidly decline. After 40 years old, fertility will be seriously damaged.
3. Normal menstruation is regular every 21-35 days, lasting for 3-7 days, with an amount of 20-60ml. If it is not in this range, then it is considered that menstruation is abnormal.
4. For women with completely normal fertility, the probability of successful pregnancy in one month is 20%, the success rate in six months is about 72%, and the success rate in one year is about 85%.
5. The longest survival time of sperm is 5 days, and eggs generally survive for 12-24 hours, so the time to conceive each month is mainly in these 6 days.
Including the day of ovulation and the first 5 days, also known as susceptible pregnancy. However, the probability of pregnancy is the highest if you share the same room within 24 hours of ovulation and 48 hours before ovulation.
Speaking of which, Jojo thought of one of my patients Lily, who had not been pregnant for half a year.
When I asked about the medical history, I found a detail problem. Lily’s husband works in a foreign country and goes home twice a month, at the beginning and at the end of the month.
However, Lily’s menstruation comes at the end of the month, regularly once every 30 days. I pointed out that their husband and wife had missed Lily’s ovulation period perfectly. Of course, pregnancy was delayed and there was no sign of it.
As it happens, there are also constant small partners asking Jojo backstage how to improve the probability of conception.
In addition to regular work and rest and balanced nutrition, because the survival time of eggs is limited, grasping the opportunity to share the same room is the key to success or failure.
Some studies have found that being vulnerable to pregnancy and having sex every day can significantly increase the success rate of pregnancy.
But, also want to consider for the body of male compatriots.
Therefore, most doctors recommend sharing the same room within 24 hours of ovulation or 1-2 days before ovulation, because this stage is the time with the highest success rate of pregnancy.
My little friend, I have to ask again, how can I know my ovulation time? The following methods can help you understand the information of ovulation.
Three Methods for Detecting Ovulation
Step 1 Measure basal body temperature
It is difficult to carry out, mainly because the sisters have said that they are lazy in the advanced stage of cancer and cannot insist on taking body temperature early in the morning.
At the same time, the basic body temperature is mainly to help sisters understand the ovulation situation, and the temperature rise occurs after ovulation, which is lagging behind. Therefore, this method is also recommended for ovulation monitoring in preparation for pregnancy.
2. Ovulation test paper and B-ultrasound were used to detect ovulation.
Generally speaking, the regular menstrual cycle lasts for 30 days, so monitoring starts on the 10th day of menstruation.
At present, these two methods are the most commonly used. B-ultrasound monitoring ovulation is more intuitive and reliable than ovulation test paper (because we can directly see the shape of follicles).
It can also be combined to monitor ovulation and guide pregnancy preparation.
Ovulation test paper showed strong positive when LH reached its peak, while women ovulated about 36 hours after LH peak appeared.
Therefore, small sisters who use ovulation test paper to guide pregnancy preparation should share the same room on the day when the test paper is strongly positive and the next day.
3. Detect progesterone level in mid-luteal phase
Progesterone level can prove ovulation in this cycle, but blood tests are required. Ordinary pregnancy preparation is not recommended for examination. If it is an infertile sister, it is another matter, because progesterone level is also used to detect ovarian corpus luteum function.
Through Jojo’s suggestion, Lily tried to monitor ovulation, and finally everything came to him who set his mind on it. He caught the last bus in 2018 and gave birth to Page’s baby with satisfaction.
Now the fairy who has a pregnancy preparation plan can also try the above methods to seize the opportunity and improve the success rate of pregnancy.
