Varicocele and Male Infertility: Know more

A varicocele is an enlarged vein in the scrotum and testicle, usually found on the left side, but possibly found on both sides of the scrotum, and very rarely only the right side. Varicoceles are relatively common, occurring in up to 15% of men. They are the leading cause of male infertility, found in 40% of men with low sperm counts. Varicoceles are treatable, as long as other fertility problems aren’t present for the male or female partner.

Symptoms of Varicocele

Many people are unaware of a varicocele until they experience fertility issues. Doctors usually conduct an abnormal semen analysis, followed by a physical exam to determine varicocele. Some men may experience signs or symptoms besides infertility. These may include:

  • A dull ache or feeling of heaviness in the testicle, especially after exercise
  • A swelling or mass in the scrotum, sometimes described as feeling like a bag of noodles
  • One testicle noticeably smaller than the other

Diagnosis

A varicocele can be diagnosed during a physical exam. If a varicocele is present, it will be visible when the urologist asks you to stand up and bare down. It disappears when you are in a horizontal position. It is possible to have a varicocele that isn’t noticeable during a physical exam and only discovered with the use of ultrasound. However, a varicocele of this size is usually left untreated, as research has not found an association to infertility in these cases.

Varicocele and Infertility

The presence of a varicocele has been associated with lowered sperm count, an increase in DNA damaged sperm, poor sperm morphology (or shape), and poor sperm movement. It isn’t clear why varicoceles causes infertility, but there are some theories. The most popular theory is that the pooled blood raises the overall temperature in the scrotum and testicles. Increased scrotal heat can be damaging to sperm.

It is also believed that poor circulation leads to increased levels of toxins, which in turn leads to poor semen health. Some people also suggest the increased scrotal pressure harms semen health.

Treatment

Treatment of varicocele depends on its size. Whether it causes you pain, there are additional fertility factors at play, and what you and your partner’s recommended fertility treatment plan looks like.

Varicocele treatment options include:

  • Microsurgical varicocelectomy – A highly skilled surgery, performed inguinal, or sublinguinal, using a microscope to aid in the repair. This surgical technique has the fewest risks and the shortest recovery time, making it the surgical treatment of choice.
  • Laparoscopic varicocelectomy – A surgery where repair is done via the abdomen. Due to the increased risk and longer recovery time, this technique is rarely chosen.
  • Percutaneous embolization treatment – A non-surgical technique with fewer risks and pain than either of the above surgical treatments. It involves a radiologist injecting into the problem vein small coils or alcohol to block the vein that is causing the trouble.

Success rates will vary from person to person, but research has found improvement in semen health in more than two-thirds of patients. Also, 30 to 50% of couples will be able to achieve pregnancy naturally after surgery.

All treatments for varicocele carry some degree of risk. Our doctors at KIMS Cuddles will be able to help you with information on risks, success rates, and recovery times.

Irregular Periods: When to Investigate

Period irregularity is something many women experience at some point, and most learn to live with it, at least for a while. A late period during a stressful month, a lighter cycle after illness, a missed period after a long flight. These variations are common and usually self-correcting. The problem is that irregular periods are also how the body signals conditions that genuinely need attention, and because the irregularity can feel familiar, it is easy to keep waiting for things to normalise when they never will without proper evaluation.Knowing where the line sits between normal variation and something worth investigating is genuinely useful.What counts as irregularA normal menstrual cycle runs anywhere from 24 to 38 days, measured from the first day of one period to the first day of the next. Variation of up to eight days between the shortest and longest cycle is considered normal. Lengths ranging between 8 and 20 days of variation are considered moderately irregular, and variation of 21 days or more is considered very irregular.Changes outside the cycle length are also irregular. Periods that are either much heavier or lighter than normal, periods that are much longer or shorter than normal, periods between periods, and periods that are absent altogether, in a woman not pregnant, breastfeeding, or in menopause,

Fertility Decline: What Women Should Know

Conversations about fertility tend to happen too late. Women often begin thinking seriously about their reproductive timeline only when they are ready to conceive. At this point, some of the most important biological facts have already been playing out for years without their awareness. The decline in female fertility with age is one of the most consistently misunderstood aspects of reproductive health, and the gap between what women know and what the biology actually shows is significant.This is not about creating anxiety. It is about giving women accurate information early enough to make genuinely informed decisions.The Fundamental BiologyA woman is born with all the eggs she is going to have in her lifetime. Her eggs age with her, decreasing in quality and quantity. Age is the single most important factor affecting a woman's fertility.Females are born with a finite number of oocytes. The number of oocytes peaks in the womb at around 20 weeks of gestation and subsequently declines steadily until approximately age 32, after which the number decreases at a greater rate until age 37, beyond which oocyte numbers drop even more rapidly.This is not something that can be slowed by fitness, diet, or general good health. Even though women today are healthier and taking better care of themselves than ever before, improved

PMOS: Causes Beyond Hormones

Most patients understand Polycystic Metabolic Ovarian Syndrome, or PMOS, as a hormonal condition. Irregular periods, elevated androgens, and ovarian cysts on an ultrasound. The hormonal picture is real, but it is only part of the story. Decades of research have made it increasingly clear that PMOS is far more complex than a hormonal imbalance in isolation. It involves the metabolic system, the immune system, the gut, and genetics, all interacting in ways that produce a condition that looks different in every woman who has it.Understanding the fuller picture of what causes PMOS matters because it changes how the condition is managed and why lifestyle interventions work as well as they do.What PMOS Actually InvolvesPolycystic Metabolic Ovarian Syndrome is a complex endocrine and metabolic disorder, typically characterised by hirsutism, hyperandrogenism, ovulatory dysfunction, menstrual disorders, and infertility. The name itself reflects what the condition truly is. The metabolic component is not secondary to the ovarian and hormonal picture. It is central to it. Treating the hormonal symptoms without addressing the underlying metabolic drivers is one reason PMOS management often produces only partial results.Insulin Resistance Sits at the CentrePMOS insulin resistance, where cells throughout the body fail to respond normally to insulin, is considered the primary pathological basis for the reproductive dysfunction seen in PMOS.
