Insights

Reduced expression of the leukaemia inhibitory factor (LIF) gene in the endometrium may cause unexplained infertility. This finding highlights LIF

Area of Science:

  • Reproductive biology
  • Molecular genetics

Context:

  • Unexplained infertility affects numerous couples worldwide.
  • Endometrial receptivity is crucial for successful implantation.
  • Leukaemia inhibitory factor (LIF) is a key cytokine involved in embryo implantation.

Purpose:

  • To investigate the expression of the endometrial leukaemia inhibitory factor (LIF) gene in patients with unexplained infertility.
  • To compare LIF gene expression levels between women with unexplained infertility and controls.

Summary:

  • Quantitative reverse transcription-polymerase chain reaction (RT-PCR) was used to measure LIF mRNA expression in the mid-luteal phase endometrium.
  • Women with unexplained infertility (n=35) showed significantly lower LIF mRNA expression compared to controls (n=20) (0.448 +/- 0.239 vs. 1.093 +/- 0.761, P < 0.01).

Impact:

  • Suggests that decreased endometrial LIF gene expression may be a significant factor contributing to unexplained infertility.
  • Highlights the potential role of LIF in the implantation process.
  • May inform future diagnostic or therapeutic strategies for infertility.

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...
