Microsurgical Epididymal Sperm Aspiration (MESA) is a minimally invasive procedure designed to address male infertility. It involves the extraction of sperm directly from the epididymis, a coiled tube responsible for transporting and storing sperm. MESA plays a crucial role in overcoming various male infertility issues, such as obstructive azoospermia, vasectomy, and congenital absence of the vas deferens.

1. Microsurgical Epididymal Sperm Aspiration (MESA) is a minimally invasive
procedure designed to address male infertility. It involves the extraction of sperm
directly from the epididymis, a coiled tube responsible for transporting and storing
sperm. MESA plays a crucial role in overcoming various male infertility issues,
such as obstructive azoospermia, vasectomy, and congenital absence of the vas
deferens. This procedure is often performed in conjunction with In Vitro
Fertilisation (IVF), a widely recognised fertility treatment where retrieved sperm
are combined with eggs in a laboratory setting to create embryos for transfer to the
uterus.
Candidates for MESA
Several factors contribute to male infertility, making some individuals better
candidates for MESA than others. In this section, we will discuss the various
causes of male infertility, the process of clinical evaluation and diagnosis, and how
MESA compares to other sperm retrieval procedures.
Causes of Male Infertility
There are numerous potential causes of male infertility, but some of the most
common factors that lead to the need for MESA include:
● Obstructive azoospermia: A blockage in the male reproductive system that
prevents sperm from reaching the ejaculate.
● Vasectomy: A surgical procedure that involves cutting or sealing the vas
deferens, the tubes that carry sperm from the testicles to the urethra,
resulting in male sterilisation.

2. ● Congenital absence of the vas deferens: A genetic condition in which the
vas deferens fail to develop properly, preventing sperm from reaching the
ejaculate.
Clinical Evaluation and Diagnosis
Before undergoing MESA, candidates must undergo a thorough clinical evaluation
and diagnostic process to determine the cause of their infertility. This evaluation
typically includes:
● Semen analysis: A laboratory test that examines a man's semen sample to
assess sperm count, motility, and morphology.
● Hormonal evaluation: Blood tests to measure hormone levels, such as
testosterone and follicle-stimulating hormone (FSH), which can provide
insight into the functioning of the reproductive system.
● Genetic testing: Screening for genetic abnormalities that may be
contributing to infertility, such as chromosomal anomalies or gene
mutations.
Comparison with Other Sperm Retrieval Procedures
MESA is just one of many sperm retrieval procedures available to address male
infertility. Other procedures, such as testicular sperm extraction (TESE),
percutaneous epididymal sperm aspiration (PESA), and testicular sperm aspiration
(TESA), may also be suitable options depending on a patient's specific needs and
circumstances. Each procedure has its own set of advantages and drawbacks, and a
fertility specialist will help determine the most appropriate method for each
individual case.
The MESA Procedure
Microsurgical Epididymal Sperm Aspiration (MESA) is a delicate and intricate
procedure that requires expertise and precision. In this section, we will discuss the
steps involved in preparing for MESA, the technique employed during the
procedure, potential risks and complications, as well as postoperative care and
recovery.
Preparing for MESA
Before undergoing the MESA procedure, patients attend a preoperative
consultation to discuss their medical history and expectations. During this

3. consultation, a thorough medical history is taken, and a physical examination is
performed. This helps the surgeon understand the patient's specific needs and
determine the most appropriate approach for the procedure.
Step-by-Step Description of the MESA Technique
The MESA procedure is performed under anaesthesia, ensuring the patient's
comfort and safety. The surgeon begins by identifying the epididymal tubules,
which are responsible for transporting and storing sperm. Once the tubules have
been located, the surgeon carefully aspirated sperm using a specialised needle.
Throughout the procedure, the aspirated epididymal fluid is closely evaluated to
ensure that an adequate amount of sperm has been retrieved.
Risks and Complications
As with any surgical procedure, MESA carries some potential risks and
complications. These may include infection, bleeding, and damage to surrounding
tissues. However, the risk of these complications is generally low, and the
procedure is considered safe when performed by an experienced surgeon.
Postoperative Care and Recovery
After the MESA procedure, patients are provided with comprehensive
postoperative care instructions to ensure a smooth recovery. This may include
guidance on pain management, wound care, and follow-up appointments. The
recovery period can vary depending on the individual, but most patients can
resume normal activities within a few days to a week.
MESA Outcomes
One of the most important aspects to consider when evaluating the effectiveness of
Microsurgical Epididymal Sperm Aspiration (MESA) is its outcomes. In this
section, we will discuss the success rates of sperm retrieval, factors that can impact
MESA outcomes, and how the retrieved sperm is utilised in IVF treatment.
Success Rates of Sperm Retrieval
MESA has been shown to yield high success rates in terms of sperm retrieval. The
procedure is particularly effective for patients with obstructive azoospermia, with
success rates often exceeding 90%. However, it is important to note that individual
results may vary, and success rates are not guaranteed for every patient.

4. Factors Affecting MESA Outcomes
Several factors can influence the success of MESA outcomes, including:
● Surgeon's expertise: The skill and experience of the surgeon performing
the MESA procedure can greatly impact the success rate of sperm retrieval.
● Patient's medical history: A patient's medical history, including previous
surgeries or health conditions, may affect the success of the procedure.
● Severity of infertility: The severity of a patient's infertility issues, such as
the extent of damage to the reproductive system, can also impact the success
of MESA.
Utilisation of Retrieved Sperm in IVF Treatment
Once sperm has been successfully retrieved through MESA, it can be utilised in
various IVF treatment procedures. These may include:
● Intracytoplasmic sperm injection (ICSI): A technique in which a single
sperm is injected directly into an egg to facilitate fertilisation.
● Embryo transfer and implantation: Following successful fertilisation, the
resulting embryos are transferred to the uterus to facilitate implantation and
pregnancy.
In conclusion, MESA is an effective treatment option for overcoming male
infertility, with high success rates in sperm retrieval. However, individual
outcomes can be influenced by various factors such as the surgeon's expertise,
patient's medical history, and the severity of infertility. The retrieved sperm is often
utilised in IVF treatments, including ICSI and embryo transfer, to increase the
likelihood of achieving a successful pregnancy.
Cost Considerations
When considering Microsurgical Epididymal Sperm Aspiration (MESA) and its
role in fertility treatments, it is essential to understand the associated costs. In this
section, we will provide an overview of the costs involved in In Vitro Fertilisation
(IVF) and surrogacy, as well as compare MESA with alternative sperm retrieval
procedures.
Overview of IVF Cost
IVF is a complex and intricate procedure that can be expensive. Several factors can
influence the cost of IVF, such as the location of the treatment, the expertise of the

5. medical team, and the specific needs of the patients. Additionally, Surrogacy Cost
in Bangalore IVF treatments often require multiple cycles, which can further
increase the overall cost. However, potential financial assistance options may be
available to help offset the costs, including insurance coverage, grants, loans, and
discounted treatment packages.
Surrogacy Cost
Surrogacy, another fertility treatment option, also comes with its own set of costs.
Factors influencing the cost of surrogacy include the surrogate's compensation,
legal fees, medical expenses, and agency fees. Like IVF, financial assistance
options may be available to help mitigate these expenses, and it is essential to
research and explore these opportunities when considering surrogacy as a fertility
treatment option.
Comparison with Alternative Sperm Retrieval Procedures
When evaluating the cost of MESA, it is crucial to consider how it compares to
alternative sperm retrieval procedures, such as testicular sperm extraction (TESE),
percutaneous epididymal sperm aspiration (PESA), and testicular sperm aspiration
(TESA). Each of these procedures may have different costs associated with them,
depending on factors such as the surgical technique, the expertise of the surgeon,
and the complexity of the case. When making a decision about which sperm
retrieval procedure is most appropriate, it is essential to weigh the potential costs
against the benefits and success rates of each method.
