What could be the reasons for a decrease in sperm count from 40 million to 2 million over the course of a month? Will this affect fertility?

Xiao Mei, 30~39 year old female. Ask Date: 2013/08/19

Dr. Xu Weikai reply Urology


Xiao Mei: Hello, with a budget of 40 million, natural conception is possible.
With a budget of 2 million, the chances of natural conception are lower.
The reasons may be related to health issues, such as staying up late, irregular sleep patterns, illness, malnutrition, or the effects of medications.
Additionally, it is important to consider the credibility of the laboratory and whether it is a qualified testing facility.
Generally, sperm production takes about 70 days.
During this period, any health issues or nutrient deficiencies can lead to defects or abnormalities in the sperm.
If there are any unclear points, feel free to ask again for further discussion and research.
Answers found online should only serve as a reference; it is essential to seek medical attention at healthcare facilities when necessary.

More Info


The significant decline in sperm count from 40 million to 2 million within a month is indeed concerning and can have a substantial impact on fertility. Sperm count is a critical factor in male fertility, and a count below 15 million sperm per milliliter is generally considered low, which can lead to difficulties in achieving pregnancy naturally.

Several factors could contribute to such a drastic decrease in sperm count. Firstly, lifestyle choices play a significant role. Poor sleep patterns, excessive alcohol consumption, smoking, and drug use can all negatively affect sperm production. Stress is another factor that can impact hormonal balance and subsequently sperm production.
Secondly, medical conditions can also lead to a decline in sperm count. Conditions such as hormonal imbalances, infections, or varicocele (enlargement of veins within the scrotum) can significantly affect sperm production and quality. Additionally, certain medications, particularly those that affect hormone levels or have side effects related to reproductive health, can also lead to decreased sperm counts.

Nutritional deficiencies should not be overlooked either. A diet lacking in essential nutrients, particularly vitamins and minerals such as zinc, vitamin C, and vitamin D, can impair sperm production. Moreover, exposure to environmental toxins, such as pesticides, heavy metals, and endocrine disruptors, can also adversely affect sperm health.

The reliability of the testing laboratory should also be considered. Variability in testing methods or equipment can lead to discrepancies in results. It is advisable to have multiple tests conducted over time to confirm any significant changes in sperm count.

Given that sperm production takes approximately 70 days, any lifestyle changes or health issues that occurred during that time could have influenced the results. If the individual experienced illness, significant stress, or changes in diet or lifestyle during that period, these could be contributing factors to the decline.

Regarding the impact on fertility, a sperm count of 2 million is significantly lower than the threshold typically required for natural conception. While it is still possible to conceive with such a low count, the chances are considerably reduced. In cases of severe oligospermia (low sperm count), assisted reproductive technologies such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) may be recommended to increase the likelihood of conception.

In conclusion, the drastic decline in sperm count from 40 million to 2 million can be attributed to various factors, including lifestyle, medical conditions, nutritional deficiencies, and environmental exposures. This decline can significantly impact fertility, making it essential to consult a healthcare provider for further evaluation and potential treatment options. Regular follow-up tests and lifestyle modifications may help improve sperm health and increase the chances of conception. If concerns persist, seeking the advice of a fertility specialist may provide additional insights and options for family planning.
