Contraindications to IVF
In vitro fertilization (IVF) is a way to transfer the pregnancy process to the laboratory through in vitro fertilization (IVF) technology, and then re implant the fertilized eggs into the mother's body to help infertile couples achieve fertility. Although IVF technology has been widely applied and promoted, not all couples are suitable for IVF. There are some contraindications that need careful consideration. The contraindications of IVF will be elaborated from four aspects.
Contraindications related to reproductive organs
First of all, IVF technology needs to achieve pregnancy through women's healthy fallopian tubes and uterus. If women have irreparable oviduct obstruction or congenital abnormality, or suffer from uterine dysplasia, endometriosis and other diseases, it is not suitable for IVF. In addition, women with serious uterine fibroma, adenomyosis and other diseases also need to be contraindicated.
Secondly, in terms of men, if they suffer from hereditary infertility or serious semen abnormalities, IVF is also not applicable. Common contraindications include: very few or complete loss of sperm, significant decline in sperm vitality, abnormal sperm morphology, etc.
Finally, for couples with reproductive organ related contraindications, such as the absence or abnormality of the woman's uterus, the man cannot provide healthy sperm, nor can he carry out IVF.
Health related contraindications
In addition to reproductive organ related contraindications, the overall health status of the couple also needs to be considered. For women receiving IVF, there are some serious chronic diseases that may lead to IVF failure or increased risk of complications. Such as serious heart and lung disease, renal failure, serious immune system disease, etc. Similarly, for men, if there are serious chronic diseases, immune system diseases, etc., it is not applicable to IVF technology.
In addition, couples who have recently suffered from serious infectious diseases, such as tuberculosis and AIDS, also need to temporarily avoid IVF, so as to prevent infection from infecting the embryo or causing serious harm to the mother.
In general, couples in poor health need to undergo a comprehensive physical examination and assessment before IVF, to ensure that they can successfully complete the IVF process and ensure the safety of pregnant women and embryos.
Age related contraindication
The success rate of IVF is closely related to the age of the couple. Generally speaking, after the age of 35, the ovarian function of women begins to decline gradually, and the quality of eggs will also decline, with a relatively low success rate. Therefore, women over 40 years old are the relative contraindication of IVF.
In addition, the age of men also has a certain impact on the success rate of IVF. The increase of male age will lead to the decrease of sperm quantity and vitality, thus affecting the success rate of IVF. Therefore, men over 40 years old are also considered as one of the contraindications of IVF.
Age is an important factor in the success rate of IVF. The age of couples should be carefully considered when considering IVF to improve the success rate.
Psychologically related contraindications
The process of IVF has high requirements on the mental and psychological endurance of couples. If couples have serious psychological problems such as mental stress, anxiety and depression, it may have a negative impact on the success rate of IVF. Therefore, if a couple has serious mental illness or has had experience of treating mental illness before, it is necessary to make a comprehensive assessment before deciding whether to carry out IVF.
In general, IVF is not suitable for all couples, and there are some contraindications that need careful consideration. It includes reproductive organ related contraindications, health status related contraindications, age related contraindications and psychosocial related contraindications. Before considering IVF, couples need to understand their own situation in detail and accept the evaluation and guidance of professional doctors to ensure the rationality of the final decision and the improvement of the success rate.
