What should I check if I can't get pregnant with my second child?

With the relaxation of these national policies, the number of people having a second child has gradually increased. However, some women of childbearing age are too old when they give birth to a second child, which leads to them finding that they cannot get pregnant at all when they want to have a second child. At this time, you need to consider whether there is some reproductive problem in your body. So what tests should be done to effectively detect the inability to conceive a second child?

What tests should I do if I can't get pregnant with my second child?

1. Check the patency of the fallopian tubes: Female infertility should first check the patency of the fallopian tubes, including fallopian tube ventilation or fluid permeation examination and hysterosalpingography, mainly to understand whether the fallopian tubes are patency, whether the development of the uterus and fallopian tubes is normal, and whether there are any deformities. It also has a therapeutic effect on those with poor fallopian tube patency, such as mild adhesion.

2. Endometrial examination: When necessary, a biopsy can be performed to understand the functional status of the endometrium. In addition, a menstrual examination is a reliable method to understand whether ovulation has occurred or the functional status of the corpus luteum. At the same time, it can also understand the size of the uterine cavity and rule out uterine cavity lesions, such as tuberculosis, uterine fibroids, etc.

3. Speculate whether ovulation occurs and predict the ovulation period: This can be determined by measuring basal body temperature, examining cervical mucus or measuring hormones.

4. Immunological examination: To understand the presence of anti-sperm antibodies, in addition to anti-sperm antibody testing, it can also be indirectly understood through post-coital tests, in vitro sperm penetration tests, etc.

5. Endocrine function measurement: For example, measuring serum estrogen and progesterone levels at different times of the menstrual cycle to understand the ovarian function. Measure basal metabolic rate to understand thyroid function. Adrenal function tests and serum prolactin measurements were performed.

Reproductive system diseases affect second pregnancy

Uterine factors: The entire complex endocrine changes, including the hypothalamus, pituitary glands and ovaries must work in a coordinated manner to achieve perfect reproductive function. The hormones secreted by the ovaries act on the endometrium, causing it to proliferate and thicken, mainly providing a fertile developmental environment for the fertilized egg so that it can take root and grow. If there is a problem with the reproductive endocrine system, it will affect ovulation or the fertilized egg will not be able to implant normally.

Some women have luteal insufficiency, which makes it too easy for them to get pregnant. The luteal phase of a normal woman should last 12-15 days. If the high temperature period is less than 10 days when measuring the basal body temperature, luteal insufficiency should be considered.

A small number of women have underdeveloped uteruses or congenital malformations, which often result in miscarriage or infertility. In addition, certain pathological changes in the endometrium, such as endometriosis, endometrial polyps, subendometrial fibroids, uterine cavity adhesions, endometrial tuberculosis, allergies, chemical toxins, malnutrition or infection, will also interfere with the normal implantation of the fertilized egg and cause miscarriage or infertility.

Fallopian tube factors: If the fallopian tubes are blocked, sperm and eggs cannot pass through smoothly, and of course pregnancy is impossible. There is even concern about ectopic pregnancy. This factor accounts for 20%-30% of all infertility causes and can be said to be the main cause of female infertility.

Only a very small number of women have congenital malformations that cause fallopian tube stenosis, blockage, or even absence of fallopian tubes. The vast majority of patients have fallopian tube blockage due to sequelae of bacterial infection, such as pelvic inflammation, tuberculosis transfer infection, or infection after induced abortion.

Peritoneal cavity factors: Since all female internal reproductive organs are located in the peritoneal cavity, if there are some physical or mechanical factors in the peritoneal cavity that hinder the conception process, it will also affect conception, such as pelvic adhesions, endometriosis, etc., which may cause changes and damage to the anatomical structure of the fallopian tubes and may cause infertility.

Most couples who are planning to have a second child are no longer in their golden childbearing period. For your second child plan, please go to a regular hospital for a pre-pregnancy check-up in time to find out the reasons and get pregnant with a second child as soon as possible.
