Dr. James Weinberger leads the Center for Male Fertility with a rare combination of surgical precision, advanced training, and patient-first compassion. Fellowship-trained in male reproductive medicine and microsurgery, he specializes in advanced diagnostics, fertility preservation, vasectomy and vasectomy reversal.


With a special focus on male reproductive health and hormone optimization, he’s one of the few male fertility specialists in the U.S. trained in high-precision reproductive microsurgery, with expertise that spans fertility preservation, hormone optimization, and supportive care for LGBTQIA+ family-building. Patients often describe him as approachable, thoughtful, and incredibly thorough: someone who listens closely and creates tailored plans that reflect both the science and the story behind each fertility journey.


“Fertility care is never one-size-fits-all. My job is to really listen, to understand what matters most to each person and help them move forward with a treatment plan that helps them build their family.” - Dr. Weinberger

Let’s Talk About Male Fertility

Male fertility matters. Period.


Male factor infertility plays a role in nearly 50% of infertility cases. That’s why a thorough male evaluation is a critical part of the reproductive process. With a dedicated center and fellowship-trained urologist on-site, we ensure that both partners receive the care they need - without delays or guesswork.

What To Expect

We start with a thoughtful evaluation and open conversation. We'll walk you through testing, explain your results in plain language, and design a treatment plan with your goals in mind.

What We Evaluate & Treat

We take a full-scope, individualized approach to care. Common conditions we help with include:


  • Low or zero sperm count (azoospermia)
  • Poor sperm motility or shape
  • Lifestyle optimization for sperm health
  • Elevated sperm DNA fragmentation
  • Varicocele (enlarged veins in the scrotum)
  • Blockages or structural issues
  • Prior vasectomy (with or without reversal)

Diagnostic Services

  • Semen Analysis: Measures sperm count, motility (movement), morphology (shape), and volume. This is often the first step in evaluating male fertility.
  • Hormone Testing: Evaluates testosterone, FSH, LH, estradiol, and prolactin levels to check for hormonal imbalances.
  • Ultrasound: A painless imaging test used to identify varicoceles (enlarged veins around the testes), blockages, or other structural issues.
  • Genetic Testing: Helps identify underlying genetic causes that could affect sperm production or quality.
  • Advanced Sperm Testing: evaluates the health of the DNA of the sperm (e.g. sperm DNA fragmentation) as well as how well the sperm functions and carries key genetic signals.
  • Testicular Mapping: Used to map sperm presence in the testicle when standard evaluations show no sperm. Performed by only a few fellowship-trained reproductive urologists in the country.
  • Sperm Cryopreservation (Sperm Freezing): Sperm cryopreservation offers an effective way to preserve fertility for future use. Whether you're planning for a family later in life, undergoing medical treatments that may impact fertility, or exploring family-building as a same-sex couple, our expert team ensures your specimens are collected, processed, and stored with the highest standards of care.

Treatment Options

  • Lifestyle Modifications: Guidance rooted in current research on modifiable factors affecting male fertility.
  • Medications: Tailored hormonal therapies that drive a patient to produce more of his own testosterone to optimize sperm production naturally.
  • Fertility-Specific Supplements: Evidence-based guidance on supplements such as CoQ10, L-carnitine, zinc, and antioxidants.
  • Post-Testosterone Fertility Restoration: Comprehensive management for men seeking fertility after anabolic or testosterone use.

  • TESA: Needle-based sperm retrieval from testicle (azoospermia).
  • TESE: Incision-based retrieval from testicle.
  • MicroTESE: Microscope-guided sperm retrieval in severe cases.
    These are combined with IVF and ICSI for maximum success.

A microsurgical procedure to reconnect the vas deferens, allowing sperm to be present again in the ejaculate. Best results occur when performed by a specialist like Dr. Weinberger with advanced microsurgery training and the ability to perform not just a vasovasostomy (vas to vas connection) but a vasoepididymostomy (vas to epididymis connection).

A minimally invasive surgery to tie off enlarged veins, improving sperm count and quality.

FAQs

It’s a good idea to consider an evaluation if you’ve been trying to conceive with a partner for 6 months or longer (if she’s under 35) or 3 months or longer (if she’s over 35), especially if you’ve had a history of medical conditions that could impact fertility - like past testicular injury, unexplained low sperm counts, or prior surgeries. Also, risk factors such as diabetes, varicoceles, hormonal issues, or lifestyle habits like regular vaping or obesity may warrant a check-up. We offer an initial consultation, hormone panels, and semen analysis to help determine where to go from here.

A general urologist treats a broad range of men’s health and urinary issues, while a reproductive urologist is a board‑certified urologist with subspecialty training focused on male fertility and reproductive health. They’re experts in male factor infertility and skilled in diagnosing conditions like low sperm count, hormonal problems, or anatomical blockages, and offering tailored treatments - from varicocele repair to assisted reproductive techniques.

Most men don’t require surgery. However, in cases of correctable conditions - like varicoceles, blockages in the reproductive tract, or undescended testes - surgery may be recommended to help improve sperm quality. Treatment decisions are always based on individualized evaluation and discussion of potential benefits and risks, and surgery is only one of several options we may consider alongside lifestyle changes or medical therapy.

Yes - fatherhood after vasectomy is possible. Options include vasectomy reversal, a microsurgical procedure to restore fertility, or sperm retrieval combined with IVF/ICSI (in vitro fertilization with intracytoplasmic sperm injection). Your reproductive urologist will review your medical history, timing of vasectomy, and personal goals to determine which path may work best.

Treatment timelines vary depending on the underlying cause and chosen approach. Lifestyle and hormonal optimization may start showing results within 3 to 6 months, while surgical interventions, healing time, and subsequent sperm improvement might span 6 to 12 months. Assisted techniques like IVF or ICSI generally take a few weeks from preparation through egg retrieval and embryo transfer. We’ll walk you through a personalized roadmap so you know what to expect.

Coverage depends on your specific insurance plan. Some plans offer partial or full coverage for fertility evaluations, semen analysis, hormone testing, or even surgical treatments. Others might classify certain procedures as elective. We’re happy to verify your coverage and provide guidance on flexible payment options and care packages, ensuring clarity before any decisions are made.
