Spermatogenesis01:41

Spermatogenesis

124.1K
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...

Infertility in Females01:28

Infertility in Females

4.9K
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...

Nondisjunction01:21

Nondisjunction

5.3K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Oogenesis02:07

Oogenesis

70.6K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Birth Control Methods

7.1K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Infertility in Males01:23

Infertility in Males

621
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...

Summary

Anti-phospholipid antibodies (aPL) can impair female fertility by affecting implantation. While some studies show aPL are more common in infertile women, their direct link to reduced fertility requires more research.

Area of Science:

  • Reproductive Immunology
  • Obstetrics and Gynecology

Background:

  • Anti-phospholipid antibodies (aPL) are associated with autoimmune conditions.
  • The role of aPL in female infertility is an area of ongoing investigation.

Purpose of the Study:

  • To review the mechanisms by which aPL may cause female infertility.
  • To determine the prevalence of aPL in infertile versus fertile women.
  • To assess if aPL positivity correlates with reduced fertility outcomes.

Main Methods:

  • Literature review of experimental data and clinical reports.
  • Analysis of studies investigating aPL and endometrial function.
  • Examination of research on aPL association with infertility and assisted reproduction outcomes.

Main Results:

  • Experimental data suggest aPL interfere with endometrial decidualization and implantation, potentially impairing fertility.
  • Some studies indicate a higher prevalence of specific aPL tests in infertile women.
  • Evidence does not strongly support a link between aPL and poor outcomes in assisted reproduction techniques.
  • Some reports suggest a decreased ovarian reserve in aPL-positive individuals, though fertility may be preserved in conditions like SLE.

Conclusions:

  • aPL may negatively impact female fertility through mechanisms affecting implantation.
  • Further research is needed to definitively establish the relationship between aPL and infertility.
  • Clinicians should counsel female patients about fertility preservation strategies when aPL are detected.
