Semen Analysis MCQ Quiz Questions And Answers

Exposure to ionizing radiation, such as X-rays or radioactive materials, can indeed cause infertility. This is because radiation can damage the DNA in reproductive cells, leading to abnormalities in sperm or eggs and making it difficult or impossible for fertilization to occur. Additionally, radiation can also damage the reproductive organs themselves, such as the ovaries or testes, further impacting fertility. Therefore, it is true that exposure to ionizing radiation can cause infertility.

The correct answer is "morphology" because it refers to the study of the form and structure of organisms. In the context of the question, it specifically refers to the structure of sperm.

Chronic heat exposure and aniline dyes have been known to have negative effects on fertility. Prolonged exposure to high temperatures, such as in saunas or hot tubs, can affect sperm production and quality in men, leading to infertility. Similarly, aniline dyes, which are commonly used in industries like textile and leather, have been linked to reproductive issues and infertility in both men and women. Therefore, it is true that chronic heat exposure and aniline dyes can cause infertility.

The patient's history can be used to diagnose infertility because it provides important information about factors that may contribute to infertility, such as previous pregnancies, medical conditions, surgeries, medications, and lifestyle habits. By reviewing the patient's history, healthcare professionals can identify potential causes of infertility and determine the appropriate diagnostic tests and treatments.

Failure to conceive after 1 year of unprotected sex is considered infertility. Infertility refers to the inability to conceive or carry a pregnancy to term after a certain period of time. In general, if a couple has been actively trying to conceive for a year without success, it is recommended to seek medical advice to determine the cause of infertility and explore possible treatment options.

Diabetes and cancer can affect fertility because both conditions can disrupt the normal functioning of the reproductive system. In the case of diabetes, high blood sugar levels can damage the blood vessels and nerves that are essential for reproductive health. This can lead to complications such as erectile dysfunction in men and irregular menstrual cycles in women. Cancer, on the other hand, can directly affect the reproductive organs or require treatments like chemotherapy or radiation that can damage the reproductive cells. These factors can significantly impact a person's ability to conceive and have a successful pregnancy.

The specimen should be analyzed within 1 hour to ensure accurate results. Analyzing the specimen promptly helps to minimize any potential changes or degradation that may occur over time. Waiting longer than 1 hour may lead to inaccurate results and compromise the validity of the analysis. Therefore, it is crucial to prioritize timely analysis to obtain reliable and meaningful data.

Semen collection after a period of sexual abstinence is recommended in order to allow for the buildup of sperm in the male reproductive system. This period of abstinence allows for the sperm count and quality to increase, which improves the chances of successful fertilization. The suggested timeframe of 48-72 hours ensures that an adequate amount of sperm is present for collection.

The correct answer is "clean specimen container" because when collecting semen by masturbation, it is important to use a clean container to ensure the sample remains uncontaminated. Using a clean specimen container helps maintain the integrity of the sample for accurate testing and analysis. Therefore, the correct option is to collect semen in a clean specimen container.

Lubricants can indeed cause problems with fertility. Certain lubricants, especially those that are petroleum-based or contain chemicals, can interfere with the sperm's ability to swim and reach the egg, reducing the chances of conception. It is recommended to use fertility-friendly lubricants or alternatives such as natural oils or saliva, which do not harm sperm motility. Therefore, the statement "Lubricants cause problems with fertility" is true.

After a vasectomy, it is recommended to start testing for sperm presence in the semen after 2 months. This is because it takes some time for the remaining sperm to clear out of the reproductive system after the procedure. Testing every month allows for regular monitoring to ensure that the vasectomy was successful and no sperm are present in the semen.

The correct answer is 20 million sperm per ml. This is because a sperm concentration of 20 million or higher per ml is considered normal for fertility. Sperm concentration refers to the number of sperm cells present in a given volume of semen. A higher concentration indicates a higher number of viable sperm, increasing the chances of successful fertilization. Therefore, a sperm concentration of 20 million or more per ml is ideal for fertility.

Alpha blockers are a class of drugs commonly used to treat conditions such as high blood pressure and benign prostatic hyperplasia. They work by relaxing the smooth muscles in blood vessels and certain organs. While alpha blockers may have various side effects, including sexual dysfunction, there is no evidence to suggest that they directly cause infertility. Therefore, alpha blockers are the correct answer to the question as they do not cause infertility compared to the other listed drugs.

A semen analysis is a routine test for infertility. This test is performed to evaluate the quality and quantity of sperm in a man's semen. It helps to determine if there are any issues with the sperm that may be causing infertility. By analyzing factors such as sperm count, motility, and morphology, the test can provide valuable information about a man's fertility potential. Therefore, the correct answer is "a routine test for infertility."

Sperm motility refers to the ability of sperm to move and swim effectively. It is considered the single most important measure of semen quality because it directly affects the sperm's ability to reach and fertilize an egg. Even if a man has a high sperm count or fertility, if the sperm are not able to move properly, it can greatly reduce the chances of successful conception. Therefore, assessing sperm motility is crucial in evaluating male fertility and determining the likelihood of achieving pregnancy.

The normal variations in semen would not be changed day to day, but several days apart would show the normal changes needed to be seen for a fertility check

Two sperm analyses are needed to confirm sterility or fertility because it is important to have multiple samples to ensure accuracy and reliability of the results. A single analysis may not provide a comprehensive picture of the person's reproductive health, as sperm count and quality can vary over time. By conducting two analyses, any potential abnormalities or fluctuations can be identified more effectively, allowing for a more accurate determination of sterility or fertility.

Iodine is not known to cause fertility problems. Nitrofurantoin, cimetidine, sulfasalazine, and spironolactone are all medications that have been associated with fertility issues.

The given sequence shows a forward progression by increasing the numbers in consecutive order. Starting from 2, each subsequent number is obtained by adding 2 to the previous number. Therefore, the next number in the sequence would be 6.

The correct answer is "the lubricant has spermicidal agents." This is because spermicidal agents are substances that are designed to kill or immobilize sperm, thus preventing fertilization. In the given options, the other statements do not directly relate to the effects of diethylstilbestrol exposure on infertility.

The normal values for sperm motility are 50% to 60%. This means that, on average, half to slightly more than half of the sperm in a semen sample are able to move effectively. Sperm motility is an important factor in male fertility, as it determines the sperm's ability to swim towards and fertilize an egg. Having a motility rate within this range is considered to be optimal for achieving successful conception.

The interval for the semen analysis is 2 to 4 weeks apart. This means that the analysis should be conducted every 2 to 4 weeks in order to monitor any changes or improvements in the semen quality. Regular testing at this interval allows for a more accurate assessment of the individual's fertility and reproductive health.

The correct answer is 1.5ml and 5.5ml. This means that the ejaculate volume should be at least 1.5ml and no greater than 5.5ml.

Maintaining sperm at room temperature is not critical. In fact, it is important to keep sperm at a slightly lower temperature than room temperature, typically around 34-36 degrees Celsius. This is because high temperatures can negatively affect sperm quality and viability. Therefore, the statement is false.

Azoospermia refers to the condition where there is no measurable amount of sperm present in the semen. This means that there are no sperm cells present in the ejaculate, which can lead to infertility as it prevents the ability to conceive naturally.

The liquification time for semen refers to the time it takes for semen to change from a gel-like consistency to a more liquid state. The correct answer is 5 to 30 minutes, which means that it typically takes between 5 to 30 minutes for semen to liquify after ejaculation.

This question is asking for factors that can affect seminal analysis. The factors listed in the question are examination after 1 hour has passed, drug use, steroid use, and period of abstinence. These factors can all potentially influence the results of a seminal analysis. Examination after 1 hour has passed may not provide an accurate representation of the semen sample, as it may have changed in composition or quality. Drug use and steroid use can also impact the composition of semen and potentially affect the analysis. Additionally, the period of abstinence, or the length of time since the last ejaculation, can affect semen volume, sperm count, and other parameters measured in a seminal analysis.

Sperm morphology is not the most important measure of semen quality. While it is an important factor, other measures such as sperm count, motility, and volume also contribute to overall semen quality. Therefore, it is not accurate to say that sperm morphology is the most important measure.

Hormone assessment and semen analysis are useful in diagnosing infertility because they provide important information about the hormonal balance and reproductive health of both the male and female partners. Hormone assessment helps evaluate the levels of key hormones involved in fertility, such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, and progesterone. Abnormal hormone levels can indicate issues with ovulation or sperm production. Semen analysis, on the other hand, examines the quantity, quality, and motility of sperm, providing insights into male fertility. By combining these two diagnostic tests, healthcare professionals can gather comprehensive information to identify the possible causes of infertility and guide appropriate treatment options.

Semen viscosity refers to the thickness or stickiness of semen. When semen is of normal viscosity, it should not show evidence of stranding, meaning it should not form long strands or clumps. Therefore, the statement "Semen viscosity should show evidence of stranding" is false.

A semen analysis is performed to evaluate the quality and quantity of sperm in a man's semen. It can be used to verify sterility after a vasectomy, as the absence of sperm in the semen confirms the success of the procedure. Additionally, if a couple is unable to conceive after one year of unprotected sex, a semen analysis can help identify any potential male infertility issues. Therefore, the test can be used to diagnose infertility.

Approximately 14% of all sperm appear normal. This means that out of every hundred sperm, around 14 of them have a normal appearance. The rest of the sperm may have abnormalities or deformities that could potentially affect fertility or the ability to fertilize an egg. It is important to note that this percentage can vary among individuals and may also be influenced by factors such as overall health and lifestyle choices.

Caffeine and computer use are not directly linked to infertility. While excessive caffeine intake has been associated with fertility issues, moderate consumption is generally considered safe. Similarly, computer use does not directly cause infertility, although prolonged exposure to heat generated by laptops may affect sperm quality. On the other hand, ethanol, smoking, and cocaine have been shown to have negative effects on fertility, including reduced sperm count and motility, hormonal imbalances, and damage to reproductive organs.

The statement "motility is rated by percentage and quantity of sperm movement" is false. Motility refers to the ability of sperm to move and is typically assessed by measuring the percentage of sperm that are actively swimming and the quality of their movement, such as speed and direction. Quantity of sperm movement is not used to rate motility.

Pesticides and heavy metals can cause infertility. Pesticides are chemicals used to kill pests, and they can disrupt the hormonal balance in the body, affecting reproductive health. Heavy metals, such as lead and mercury, can accumulate in the body over time and have toxic effects on reproductive organs. Both pesticides and heavy metals have been linked to decreased fertility and increased risk of infertility. Protein shakes and "amazodine bio hazards" are not known to directly cause infertility.

Low ejaculatory volume may indicate retrograde ejaculation, obstruction of ejaculatory duct, incomplete collection, and androgen deficiency. Retrograde ejaculation occurs when semen is redirected into the bladder instead of being expelled through the penis. Obstruction of the ejaculatory duct refers to a blockage that prevents semen from being ejaculated properly. Incomplete collection refers to the inability to collect a sufficient amount of semen during ejaculation. Androgen deficiency, which is a lack of male sex hormones, can also lead to low ejaculatory volume.
