Male fertility is of paramount importance as it is vital for human reproduction. Unfortunately, there has been a concerning increase in male infertility cases in recent years. There has been a significant decline in male fertility rates worldwide, known as the “Male Fertility Crisis.” This crisis poses challenges for couples struggling to conceive – along with numerous causes and risk factors linked to male reproductive health. It is crucial to address this situation, and awareness of prevention and treatment options is essential.
What is Male Fertility Crisis?
The decline in the reproductive health of a male is commonly referred to as Male Infertility. This condition can be attributed to underlying issues, such as reduced sperm quality and quantity. Additionally, there is a correlation between sperm motility and Male Fertility Rate. In recent years, researchers have brought attention to a concerning trend – a rapid decline in the sperm count of males. This decline has not been observed in specific countries – but globally. Males are diagnosed with significant changes in sperm count, motility and semen quality. The crisis is generating a lot of discussion and concern regarding its possible long-term effects on human fertility and reproductive health.
Symptoms of Male Fertility Issues:
Male fertility can manifest in various ways. Several symptoms can indicate male fertility, including:
- Problems with Sexual Function – There is difficulty in ejaculation, whether it is a whole amount or little amount of semen. Also, there can be a decrease in sexual desire and an ongoing problem sustaining erection (This term is called Erectile Dysfuctioning)
- There is pain or swelling in the testicular region. You can also feel a lump.
- It’s possible that the respiratory system may have issues, causing the male to experience difficulty with smelling.
- There can be abnormal breast development, also called Gynecomastia
- Men may experience hair loss on their bodies or face, which could indicate a hormonal or chromosomal issue.
- There is a decreased amount of sperms (Normal Range = 15 million sperms / Liter of Semen OR Sperm Count = 39 million / Ejaculation)
- Male is facing continuous modifications in sexual drive, and libido fluctuates
Causes of Male Fertility Issues:
Various reasons can lead to male fertility issues. Some issues can be attributed to medical and others are due to environmental factors.
Medical Causes
Following are the common medical causes of Male Fertility;
Varicocele
Varicocele is mainly linked with the enlargement of veins within the scrotum of the testicles. The primary function of these veins is to transport the non-oxygenated blood out of the scrotum. When the veins did not pool out the blood – it ultimately led to enlargement and infertility.
Sexually transmitted infections (STIs)
Many sexually transmitted diseases can lead to male fertility issues. Gonorrhea, Chlamydia, HIV and HPV are common STDs that can affect the male’s reproductive system.
Hormonal Disorders
Male fertility is significantly linked with reproductive hormones. Testosterone is a male reproductive hormone that regulates sex drive and is essential for red blood cells and sperm production. The usual range of Testosterone hormone is 10 to 35 nanomoles per litre of blood.
Environmental Causes of Male Fertility:
Male fertility is also affected by environmental or extrinsic factors. The common environmental causes are;
- Exposure to harmful chemicals that are toxic to our bodies, like pesticides, heavy metals, and certain medications (Nitrofurantoin and Dapsone)
- Male fertility is also affected by Lifestyle, Smoking habits, consumption of excessive alcohol and spermicides
- Obesity and an imbalanced diet can affect sperm counts
- A high temperature in the environment can affect sperm motility
- Stress and psychological factors can also affect the growth and ageing of the sperm
Risk Factors for Male Fertility:
Various factors can raise the chances of male fertility problems; advancing age, persistent health conditions (like diabetes or hypertension), particular occupations – that expose one to chemicals, heat, or radiation, and a family history of previous reproductive disorders.
Types of Male Infertility:
Three primary types of male infertility exist; Pretesticular, Testicular, and Post-testicular.
Pretesticular infertility
This type of infertility is related to reproductive hormonal issues like production and regulation
Testicular Infertility
This type of infertility is caused by problems like testicular damage or genetic abnormalities – affecting sperm production and decreased quality.
Post-testicular infertility
This type of infertility occurs due to an obstruction or blockage in the reproductive tract – preventing the normal flow of sperm.
How to Check Male Fertility?
Male Fertility evaluation involves a comprehensive examination by a healthcare professional. He may ask for different tests – after analysing your situation. The most common tests are semen analysis tests, hormone level assessments, genetic testing, and imaging studies – ultimately evaluating the male reproductive organ.
How Common is Male Infertility?
It’s important to acknowledge that male infertility is a prevalent concern affecting around 7% to 8% of men globally. Infertility isn’t exclusively a male issue – it can often result from a combination of male and female factors.
Treatment and Prevention:
Different treatment options are available for male infertility – depending on the root cause. These options include medication, surgery, lifestyle changes, and assisted reproductive technologies (ART) like in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI).
Keeping ourselves healthy and safe is important – so prevention is essential.
Here are some tips by a Medical Writer from The Academic Papers UK to help prevent health issues:
Maintain a Healthy Lifestyle
Regular exercise, a balanced diet, and a healthy weight are essential – maintaining a healthy lifestyle. It is also noteworthy to avoid smoking and excessive alcohol consumption.
Minimize exposure to Environmental Toxins
Take precautionary measures to avoid harmful chemicals and substances – at the workplace and at home.
Practice Safe Sex
It’s essential to prioritise safety by taking precautions like using condoms to prevent sexually transmitted infections (STIs). Additionally, it’s beneficial to schedule regular STI screenings.
Manage Stress
Adopt techniques like exercise, meditation, or counselling. This can help reduce the impact of stress on reproductive health.
Conclusion:
The decrease in male fertility rates is a pressing issue – presenting significant challenges for couples desiring to conceive. Understanding male infertility’s causes, symptoms, and risk factors is imperative to ensure swift intervention and treatment. By implementing preventative measures, adhering to a healthy lifestyle, and seeking medical aid – one can mitigate the impact of male fertility problems and improve reproductive health outcomes.
