Oral hormonal contraceptives (OC) offer non-contraceptive benefits, including reduced risks for benign and malignant tumors like breast, endometrial, and colorectal cancers. They also alleviate endometriosis symptoms like dysmenorrhea.
Area of Science:
- Gynecology
- Oncology
- Pharmacology
Context:
- Oral hormonal contraceptives (OC) are widely used for their contraceptive effects.
- Emerging evidence suggests significant non-contraceptive health benefits associated with OC use.
Purpose:
- To comprehensively review the non-contraceptive benefits of oral hormonal contraceptives, focusing on their impact on various benign and malignant tumors.
- To evaluate the association between OC use and conditions such as endometriosis, fibroids, and specific cancer types.
Summary:
- OC use is linked to a diminished risk of benign breast tumors, uterine fibroids, and ovarian cysts.
- While not directly improving endometriosis, OC effectively decrease associated dysmenorrhea.
- Modern low-dose OCs do not elevate risks for liver adenomas/carcinomas or melanoma.
- Current data indicate no increased risk for breast carcinoma in OC users; long-term use correlates with decreased endometrial and colorectal carcinoma risks.
- OCs do not directly influence cervical cancer but may indirectly impact it via behavioral changes. No increased risk for vulvar or vaginal carcinoma is observed.
Impact:
- Highlights the multifaceted health advantages of oral contraceptives beyond contraception.
- Provides crucial information for healthcare providers and patients regarding the oncological and gynecological implications of OC use.
- Supports informed decision-making for individuals considering or currently using oral hormonal contraceptives.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
Hormonal Regulation of the Menstrual Cycle
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.
Birth Control Methods
Hormonal Control of the Ovarian Cycle
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...
