Summary
Steroidogenic factor-1 (SF-1) is not expressed in ovarian endometriosis or normal endometrium glands and stroma. However, SF-1 is strongly expressed in adjacent ovarian mesenchymatous cells, suggesting a role in local steroidogenesis.
Area of Science:
- Reproductive biology
- Endocrinology
- Gynecologic pathology
Background:
- Steroidogenic factor-1 (SF-1) is crucial for steroidogenesis.
- A potential role for SF-1 in ovarian endometriosis has been hypothesized.
- In situ expression of SF-1 in ovarian endometriosis remains uncharacterized.
Purpose of the Study:
- To investigate the in situ expression of SF-1 in ovarian endometriosis.
- To compare SF-1 expression in endometriosis with normal eutopic endometrium.
- To explore the potential role of SF-1 in the pathogenesis of ovarian endometriosis.
Main Methods:
- Immunohistochemistry was employed to detect SF-1 expression.
- Samples included 30 cases of ovarian endometriosis (proliferative and secretory phases) and 10 normal eutopic endometria.
- Adjacent ovarian cortical and medullary mesenchymatous cells were also examined.
Main Results:
- No SF-1 immunoreactivity was detected in the glands or stroma of ovarian endometriosis or eutopic endometrium.
- Strong SF-1 immunoreactivity was consistently observed in adjacent ovarian cortical and medullary mesenchymatous cells.
- SF-1 expression in these ovarian cells was independent of the menstrual cycle phase.
Conclusions:
- SF-1 is absent in the glandular and stromal compartments of ovarian endometriosis and eutopic endometrium.
- The presence of SF-1 in adjacent ovarian mesenchymatous cells suggests their involvement in local steroidogenesis.
- These findings challenge previous hypotheses and highlight a potential novel mechanism in endometriosis-associated steroidogenesis.

02:07Oogenesis
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...
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...

01:22Hormonal Regulation of the Menstrual Cycle
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

01:27Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
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...

01:20Folliculogenesis
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...
