Insights

Fertility preservation is crucial for young women facing gonadotoxic treatments for non-cancerous conditions. Immature oocyte retrieval, in-vitro maturation, and vitrification offer a viable fertility preservation option when ovarian stimulation is not possible.

Area of Science:

  • Reproductive medicine and endocrinology.
  • Oncology and hematology.
  • Genetics and immunology.

Background:

  • Gonadotoxic agents used for various non-oncological conditions, such as chromosomal abnormalities and autoimmune disorders, can cause premature ovarian failure.
  • Young women undergoing such treatments require fertility preservation strategies.
  • Ovarian stimulation may be contraindicated or impossible for some patients.

Purpose of the Study:

  • To highlight the importance of fertility preservation in young women undergoing gonadotoxic therapies for non-oncological conditions.
  • To present immature oocyte retrieval, in-vitro maturation, and vitrification as a key fertility preservation method.

Main Methods:

  • Retrieval of immature oocytes from patients.
  • In-vitro maturation (IVM) of retrieved oocytes.
  • Vitrification (cryopreservation) of mature oocytes.

Main Results:

  • Immature oocyte retrieval followed by IVM and vitrification is effective for fertility preservation.
  • This method is particularly beneficial for women who cannot undergo conventional ovarian stimulation.
  • It provides a crucial option when contraindications to ovarian stimulation exist.

Conclusions:

  • Fertility preservation is essential for young women treated with gonadotoxic agents for non-oncological conditions.
  • Immature oocyte retrieval, in-vitro maturation, and vitrification represent a valuable and accessible fertility preservation strategy.
  • This approach expands fertility options for patients unable to undergo ovarian stimulation.

Infertility in Males01:23

Infertility in Males

Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
Infertility in Females01:28

Infertility in Females

Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of endometrial...
Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
In Vitro Fertilization01:24

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
Meiosis II01:57

Meiosis II

Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each containing...
