The relationship between IVF and ligation
Ligation is a common method of contraception. It can prevent sperm from combining with egg by blocking the vas deferens or fallopian tubes, so as to achieve the purpose of contraception. However, some families still hope to have their own children after ligation for various reasons. So they began to think about IVF as an assisted reproductive technology. Is there any relationship between IVF and ligation? Can IVF be performed after ligation? The following four aspects will be elaborated.
1. Effect of ligation on fertility
First, we need to understand the impact of ligation on fertility. The principle of ligation operation is to block the fallopian tube or vas deferens through surgical operation to prevent the combination of sperm and egg, so as to achieve the purpose of contraception. However, ligation itself did not completely destroy fertility, but temporarily blocked the pregnancy channel. Therefore, in a period of time after the operation, if you want to restore fertility, you can choose to perform tubal recanalization or sperm removal and other auxiliary means to achieve natural pregnancy.
However, if the time after ligation is too long, or the operation is improper, resulting in the destruction of the fallopian tube or vas deferens, then the possibility of natural pregnancy is very small. At this time, IVF becomes a feasible option.
2. Principle of IVF after ligation
In vitro fertilization embryo transfer (IVF-ET) is a kind of assisted reproductive technology that is separated from the natural mating process. The process includes the following steps: help women ovulate more through hormone therapy, and then in vitro fertilization of the taken eggs and sperm in the in vitro laboratory. After cultivating healthy embryos, the embryos are transferred to the female uterus to achieve pregnancy.
Although the ligation operation blocked the fallopian tube or vas deferens, it did not affect the normal production of eggs and sperm. Therefore, even if the fallopian tube or vas deferens are ligated, pregnancy can still be achieved through IVF technology. After ligation, women can still promote multiple ovulation of eggs through adjuvant hormone therapy, and then conduct in vitro fertilization embryo transfer, and finally realize the birth of IVF.
3. Applicable population for IVF after ligation
The contraceptive effect of ligation is reliable, but in some special cases, there are still some people who want to realize their reproductive dreams through IVF technology. Applicable groups include:
(1) Couples with shorter ligation time and no obvious damage to the fallopian tube or vas deferens.
(2) Couples who failed in fallopian tube recanalization or sperm removal after ligation.
(3) Couples who have undergone ligation for a long time and whose oviducts or vas deferens have been seriously damaged or destroyed.
After ligation, IVF can be selected as an assisted reproductive technology to help the applicable population realize their reproductive dreams.
4. Hospital selection for IVF after ligation
IVF is a complex assisted reproductive technology, which requires a professional medical team and good laboratory equipment. It is very important to choose a formal and reliable hospital.
There are many professional reproductive hospitals in China that provide IVF services, such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine. When selecting a hospital, factors such as the professional level, equipment and facilities, success rate, diagnosis and treatment experience, patient evaluation, etc. of the hospital can be considered, as well as factors such as the geographical location and transportation convenience of the hospital, so as to better accept treatment and follow-up.
Summary:
The effect of ligation on fertility is reversible. Fertility can be achieved by assisted means such as fallopian tube recanalization or test tube baby. IVF can still be performed after ligation because ligation does not affect the normal production of eggs and sperm. There are certain restrictions on the applicable population for IVF after ligation surgery, but there are still many couples who can realize their reproductive dreams through this technology. Choosing a regular hospital is the key to IVF, and only selecting a suitable hospital can achieve better therapeutic effect.
