Inthe reproductive clinic, we often encounter some regrettable cases. For example, a couple with a long history of heavy smoking and drinking found that the woman's ovarian reserve was extremely poor during a fertility evaluation, and there were almost no viable sperm in the man's semen. This clearly shows that certain lifestyle choices are continuing to consume valuable reproductive resources.
Thousands of chemical substances such as nicotine, benzopyrene, and cadmium in cigarettes can cause direct and multiple damage to reproductive function.
Nicotine, benzo[a]pyrene, cadmium, and thousands of other chemicals found in cigarettes can cause direct and multifaceted damage to reproductive functions.
▶for men

,,,.More seriously, it destroys the DNA integrity inside the sperm, and this damage can accumulate, affecting fertilization ability and embryo health.
▶for women

.Toxic substances (such as cadmium) accumulate in the ovaries, poisoning follicular cells, causing premature decline in ovarian reserve function. Studies have shown that women who smoke may enter menopause 1-4 years earlier than non-smokers. Special attention should be paid to the fact that the harm of passive smoking is equally huge.
There is no safe "moderate" threshold for alcohol for fertility.

A common misunderstanding is that as long as you choose assisted reproductive technologies such as IVF, you can ignore the influence of basic living factors such as alcohol and tobacco.
,,.In fact, any advanced reproductive technology is inseparable from high-quality "seeds"(sperm and eggs) and good "soil"(maternal environment). Tobacco and alcohol are the primary factor in destroying these basic conditions at the source. When the quality of sperm and eggs itself is poor and the endocrine environment is disrupted, the success rate of the technology will be greatly reduced.
Maintaining fertility is a crucial health investment.
,.Quit smoking and drink not to "listen to the doctor." It is to give future children a healthier starting point and give yourself one more chance to succeed. If you are already preparing for pregnancy or preparing test tubes, it is still too late to start adjusting your lifestyle. Finally, I wish every expectant parent a happy pregnancy!
