IVF Centre and Reproductive Care in Siliguri - Dr. Prasenjit Kr. Roy

Infertility is a medical condition that can affect both male and female partners. However, advancements in assisted reproductive technologies (ART) provide structured medical pathways for patients seeking clinical management. Backed by over two decades of clinical experience in reproductive medicine, Dr. Prasenjit Kr. Roy offers comprehensive fertility evaluations and specialized clinical treatments at his practice in Siliguri, combining evidence-based medical protocols with advanced laboratory standards.

Assisted Reproductive Treatments and Clinical Services

Because underlying etiologies vary among patients, individualized treatment protocols are established following thorough diagnostic evaluations. Dr. Prasenjit Kr. Roy tailors clinical management to each patient's specific diagnostic findings. Available clinical services include:

In Vitro Fertilization (IVF)

An established assisted reproductive procedure involving controlled ovarian stimulation, transvaginal oocyte retrieval performed under anesthesia, and co-incubation of gametes in a specialized laboratory environment.

Following fertilization and embryonic development through the blastocyst stage, a selected viable embryo is transferred into the uterine cavity to achieve pregnancy.

Intrauterine Insemination (IUI)

A clinical procedure indicated for mild male factor infertility or cervical factor conditions. The protocol involves monitoring the ovulatory cycle, occasionally utilizing ovulation induction agents.

On the day of ovulation, prepared, motile spermatozoa obtained via seminal processing are placed directly into the uterine cavity using a fine catheter.

Intracytoplasmic Sperm Injection (ICSI)

A specialized micromanipulation technique indicated for severe male factor infertility, such as oligospermia, asthenozoospermia, or teratozoospermia. ICSI involves the direct microinjection of a single selected spermatozoon into the cytoplasm of a mature oocyte.

This technique assists in overcoming specific fertilization barriers and may be utilized in cycles with previous conventional fertilization failure.

Surgical Sperm Retrieval (TESA, TESE, MESA, PESA)

Minimally invasive or microsurgical sperm retrieval procedures utilized in cases of azoospermia (obstructive or non-obstructive) to obtain spermatozoa for assisted reproductive procedures such as ICSI.

These techniques enable patients with severe male factor conditions to utilize their own gametes in assisted reproductive treatment.

Operative Endoscopy (Laparoscopy and Hysteroscopy)

Minimally invasive endoscopic procedures utilized to evaluate and treat structural abnormalities impacting reproductive function or embryo implantation. Diagnostic and therapeutic laparoscopy addresses conditions such as pelvic pathology, ovarian cysts, tubal occlusion, and endometriosis.

Hysteroscopy permits direct visualization of the uterine cavity via the cervix for the resection of polyps, adhesions, or septa, supporting clinical management.

Fertility Preservation

Cryopreservation protocols - including oocyte, spermatozoa, and embryo freezing - utilized for medical indications or elective preservation prior to gonadotoxic therapies.

Vitrification protocols utilize ultra-rapid cooling technology to ensure high post-thaw survival and clinical viability in subsequent assisted reproductive cycles.

Clinical Indications for Assisted Reproductive Consultation

Professional medical consultation is recommended when patients encounter challenges in achieving pregnancy after regular, unprotected intercourse. Early clinical evaluation facilitates accurate diagnosis and timely management. Indications for specialist evaluation include:

• Failure to achieve pregnancy after 12 months of regular, unprotected intercourse (or 6 months for female partners aged 35 years and older).
• Tubal occlusion or anatomical pathology impacting gamete transport.
• Severe male factor infertility, including oligospermia, asthenozoospermia, or azoospermia.
• Endocrine and metabolic conditions, such as Polycystic Ovary Syndrome (PCOS) or thyroid dysfunction affecting ovulation.
• Endometriosis and associated pelvic inflammatory pathology impacting reproductive health.
• History of two or more consecutive pregnancy losses requiring comprehensive diagnostic evaluation and potential pre-implantation genetic testing (PGT).

Professional Practice in Assisted Reproduction

Clinical practice in reproductive medicine combines structured medical protocols with specialized laboratory standards to support patient care. Key aspects of clinical practice include:

• Accredited Clinical Standards: Adherence to established healthcare safety, regulatory compliance, and laboratory quality control protocols.
• Specialized Fellowship Training: Fellowship training in Reproductive Endocrinology and Infertility completed at Tel Aviv University, Israel, under established international specialists.
• Advanced Laboratory Infrastructure: Controlled embryology laboratory environment equipped for precise gamete handling, vitrification, extended embryo culture, and specialized sperm preparation.
• Comprehensive Diagnostic Support: In-house diagnostic evaluations facilitating accurate clinical assessment and individualized treatment planning for both partners.
