Summary
Insulin-like growth factor-1 (IGF-1) plays a key role in gynecological health, influencing cancer risk, benign tumors like myomas, and pregnancy outcomes. Understanding IGF-1 levels can aid in diagnosing and managing various conditions.
Area of Science:
- Gynecology
- Endocrinology
- Reproductive Biology
Background:
- Insulin-like growth factor-1 (IGF-1) is implicated in tissue proliferation, reproduction, and cancer development.
- Dysregulation of IGF-1 and its binding proteins is linked to gynecological conditions.
Purpose of the Study:
- To review the role of IGF-1 in gynecology, focusing on its involvement in cancer, benign proliferations, and pregnancy.
- To highlight the diagnostic potential of IGF-1 as a biomarker.
Main Methods:
- Literature review of studies investigating IGF-1 in gynecological tissues and conditions.
- Analysis of associations between IGF-1 levels and risks for breast, cervical, ovarian, and endometrial cancers.
- Examination of IGF-1's role in uterine myomas, endometriosis, polycystic ovary syndrome (PCOS), and IVF implantation.
Main Results:
- High IGF-1 and low IGF binding protein-3 (IGFBP-3) correlate with increased breast cancer risk in perimenopausal women.
- Elevated IGF-1 levels are associated with higher risks of cervical, ovarian, and endometrial cancers.
- IGF-1 promotes myoma growth, influences reproductive tissue differentiation, and is linked to PCOS and endometriosis, potentially explaining infertility.
- IGF-1 is crucial for embryo implantation and successful pregnancy, serving as a potential marker for pregnancy complications.
Conclusions:
- IGF-1 is a significant factor in gynecological health, impacting cancer development, benign tumors, and reproductive functions.
- Monitoring IGF-1 levels may offer diagnostic and prognostic value for various gynecological conditions and pregnancy outcomes.
- Further research is needed to elucidate the relationship between systemic and local IGF-1 levels in different conditions.

01:15Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

01:24Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

01:30Hormonal Control of the Ovarian Cycle
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

01:15Development of the Sexual Organs in the Embryo and Fetus
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...

01:28Infertility 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.
