Birth Control Methods01:22

Birth Control Methods

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 vasectomy...
Testosterone: Functions and Regulation01:26

Testosterone: Functions and Regulation

The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
Target Cell Response to Hormones01:22

Target Cell Response to Hormones

Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
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 Cycle01:22

Hormonal 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.
Hormonal Regulation of Blood Pressure01:17

Hormonal Regulation of Blood Pressure

Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...

Summary
This summary is machine-generated.

Oral contraceptive (OC) use in women athletes is linked to lower baseline testosterone levels. However, competition robustly increases testosterone in both OC users and non-users.

Area of Science:

  • Sports Science
  • Endocrinology
  • Women's Health

Background:

  • Testosterone (T) influences athletic performance and behavior.
  • Oral contraceptives (OCs) are widely used by female athletes.
  • The impact of OCs on testosterone levels and exercise-induced changes in athletes is not fully understood.

Purpose of the Study:

  • To investigate the relationship between oral contraceptive use and salivary testosterone levels in women athletes.
  • To examine the effect of athletic competition on salivary testosterone in OC users versus non-users.

Main Methods:

  • Saliva samples were collected from women athletes (soccer, volleyball, softball, roller derby) before and after competition.
  • Salivary testosterone levels were measured and compared between oral contraceptive users (n=29) and non-users (n=51).

Main Results:

  • Women using OCs exhibited significantly lower mean salivary testosterone levels than non-users.
  • Athletic competition was associated with a significant increase in salivary testosterone for all participants.
  • Both OC users and non-users demonstrated comparable increases in testosterone following competition.

Conclusions:

  • Oral contraceptive use is a significant factor influencing baseline testosterone levels in women athletes.
  • Competition stimulates a similar testosterone increase in both OC users and non-users, independent of baseline differences.
  • Further research is needed to understand the mechanisms behind competition-induced testosterone increases and their implications for OC users.
