Male Infertility
Male infertility affects many couples who want to build a family. Studies show a male factor plays a role in about half of all infertility cases, either alone or together with a female factor.
At Riverstone Urology in Cypress, Dr. Russell Libby evaluates and treats male infertility with a clear goal. Understand the cause, protect long term health, and give couples a realistic path toward pregnancy with the least invasive plan that makes sense.
What Is Male Infertility?
Male infertility means a couple has trouble achieving pregnancy after regular, unprotected intercourse for at least twelve months, or six months when the female partner is older than thirty five.
Male Factor Infertility Relates To Three Main Issues
- Not enough sperm
- Sperm with poor movement or shape
- A blockage or problem with sperm delivery
Hormones, testicles, ducts, and sexual function all play a part in this system. Problems in any step reduce the chance of pregnancy.
Signs And Symptoms
Many Men Feel Normal And Notice No Symptoms Other Than Difficulty Conceiving. Others See Or Feel Changes Such As
- Trouble achieving pregnancy with a partner after a year of trying
- Low sex drive
- Difficulty getting or keeping an erection
- Ejaculate volume that seems lower than in the past
- Pain, swelling, or a lump in the testicles or scrotum
- A “bag of worms” feeling above the testicle, often from a varicocele
- Decreased facial or body hair or breast enlargement
- History of testicular injury, surgery, or cancer treatment
Any of these signs plus difficulty conceiving deserves a focused fertility evaluation.
Common Causes And Contributing Factors
Male infertility has many causes. Often more than one factor is present.
Sperm Production Problems
- Reduced sperm count
- Poor sperm movement
- Abnormal sperm shape
- Combination of these findings
Causes include genetic conditions, prior injury, infection, heat exposure, toxins, and some medicines.
Varicocele
Varicocele describes enlarged veins above the testicle. It often feels like a soft cluster of ropes in the scrotum. Studies link varicocele to reduced sperm quality and quantity. It appears in a large share of men evaluated for infertility.
Hormonal Disorders
- Low testosterone from testicular or pituitary problems
- High prolactin from pituitary tumors or medicines
- Thyroid disorders
- Metabolic issues such as obesity and diabetes
Sperm Transport Or Blockage Issues
- Prior vasectomy
- Congenital absence or scarring of the vas deferens
- Blocked ejaculatory ducts
- Scarring from infection or surgery
Sexual Function Problems
- Erectile dysfunction
- Premature ejaculation
- Retrograde ejaculation, where semen flows backward into the bladder
Lifestyle And Environmental Factors
- Tobacco use
- Heavy alcohol intake
- Anabolic steroids or testosterone therapy
- Heat exposure to the testicles from hot tubs or tight clothing
- Pesticides, heavy metals, and other toxins
- Obesity and inactivity
Unexplained Or Idiopathic Infertility
In some men, semen tests and hormone levels appear normal and no clear cause shows up on exam or imaging. Guidelines describe this group as idiopathic infertility. It does not mean nothing is wrong. It means current tests do not yet reveal the exact reason.
When To See Dr. Libby
You Should Schedule A Fertility Evaluation If
- You and your partner have tried to conceive for twelve months without success
- Your partner is over thirty five and you have tried for six months without success
- You have a history of undescended testicle, testicular surgery, cancer therapy, or significant trauma
- You notice a scrotal lump, varicocele, breast enlargement, low sex drive, or erection changes
- You have already started fertility workup on your partner and have no male evaluation yet
Early evaluation often reduces delays and helps couples avoid unnecessary treatment focused only on the female partner.
How Dr. Libby Evaluates Male Infertility
Male Infertility Care At Riverstone Urology Follows Current Aua And Asrm Guidelines.
Detailed History
Topics include
- Duration of infertility and prior pregnancies with this or other partners
- Sexual history and timing of intercourse
- Past infections, sexually transmitted diseases, or significant fevers
- Testicular injury, surgery, or torsion
- Childhood history of undescended testicle
- Cancer treatment, chemotherapy, or radiation
- Use of testosterone, anabolic steroids, or other hormone products
- Medicines, supplements, tobacco, alcohol, and drug use
- Family history of infertility, cystic fibrosis, or genetic disorders
Physical Exam
Focus areas
- Body build, hair pattern, and breast tissue for hormone clues
- Testicle size and firmness
- Presence of varicocele
- Penile anatomy and prostate exam when indicated
Semen Analysis
Semen testing is central to male infertility workup.
- Usually two samples collected on different days
- Collected after two to seven days of abstinence
- Lab evaluates volume, count, movement, and shape
- Results guide further testing and treatment choices
Hormone Testing
Blood tests often include
- Total testosterone
- FSH and LH
- Prolactin
- Thyroid function
- Additional labs based on findings
These help separate testicular causes from pituitary or hypothalamic causes.
Imaging And Specialized Tests
Depending on results, Dr. Libby may recommend
- Scrotal ultrasound to assess varicocele, masses, or structure
- Transrectal ultrasound for suspected ejaculatory duct blockage
- Genetic tests for very low sperm counts or absent sperm
- Cystic fibrosis gene testing when vas deferens is absent
- Testicular biopsy in select men with no sperm in the ejaculate
The goal is to define a cause when possible and map out realistic options.
Treatment Options At Riverstone Urology
Treatment depends on the cause, how severe the sperm problem is, the female partner’s age and health, and each couple’s timeline and values. Many causes are treatable or at least improvable.
Lifestyle And Medical Risk Factor Changes
Dr. Libby often starts with
- Stopping tobacco and anabolic steroids
- Reducing alcohol intake
- Weight loss for men with central obesity
- Better control of diabetes and blood pressure
- Treatment for sleep apnea
- Avoidance of high heat exposure to the testicles
These steps support general health and often improve semen results over time.
Treatment For Sexual Function Problems
When erectile dysfunction or ejaculation problems limit intercourse, Dr. Libby can
- Use oral medicines for erection support
- Offer injection therapy or other ED treatments described on separate Riverstone Urology pages
- Address premature ejaculation
- Work with counselors or sex therapists for performance anxiety and relationship stress
Better sexual function often raises natural conception chances, even before advanced fertility treatment.
Hormone Based Treatments
For men with clear hormonal causes
- Medicines that stimulate the body’s own hormone production, such as hCG or selective estrogen modulators, in selected cases
- Treatment of high prolactin or thyroid disorders
- Careful review of any outside testosterone use, because standard testosterone therapy often lowers sperm counts and is usually avoided in men trying to conceive
Hormone plans follow guideline based recommendations and require regular monitoring.
Surgery To Improve Sperm Delivery
Examples include
- Varicocele repair when varicocele links to poor semen parameters and an abnormal exam
- Vasectomy reversal in men who previously chose vasectomy and now wish to conceive
- Surgery to correct ejaculatory duct obstruction
- Reconstruction of blocked ducts where anatomy allows
Studies show selected men who undergo varicocele repair or reversal procedures often see improved semen results and higher natural pregnancy rates.
Sperm Retrieval And Assisted Reproductive Technology
When semen counts remain very low or no sperm appear in the ejaculate, Dr. Libby may work with fertility specialists to retrieve sperm directly. Options include
- Testicular sperm extraction or aspiration
- Epididymal sperm aspiration in some obstruction cases
Retrieved sperm then move into fertility treatment such as
- Intrauterine insemination, IUI
- In vitro fertilization, IVF
- Intracytoplasmic sperm injection, ICSI, where a single sperm enters an egg under a microscope
This approach often helps couples even when sperm counts in the ejaculate are extremely low.
Emotional And Relationship Support
Infertility Affects More Than Lab Numbers. Men Often Describe
- Guilt or shame
- Strain in the relationship
- Stress around timed intercourse and testing
- Worry about masculinity or sexual identity
Dr. Libby encourages couples to attend visits together whenever possible. He also supports referrals for counseling and support groups when stress rises. Research shows that attention to emotional health improves quality of life and often helps couples stay engaged with treatment.
