Produce hormones2
- The endocrine glands produce hormones, which are distributed by the vascular system to the many body tissues, subsequently these organs are richly vascularized. (edu.au)
- It contains several groups of neurosecretory cells called nuclei which produce hormones. (excellup.com)
Maturation1
- However, the question as to which hormonal factors are most essential for stimulating skeletal maturation in this condition remains controversial 7 13) . (e-apem.org)
Regulate2
- Androgens regulate the development of the embryo, determining whether it is a male or a female (male in the presence of androgens and female in the absence of androgens). (encyclopedia.com)
- These hormones reach the pituitary gland through a portal circulatory system and regulate the functions of the anterior pituitary. (excellup.com)
Abnormalities1
- 4 However, most cases of male undermasculinisation do not have molecular abnormalities in the androgen receptor gene or abnormalities in androgen receptor binding, and therefore remain undiagnosed. (bmj.com)
Insulin3
- First, it is important to note that insulin is a very important hormone in the human body and too much or too little of it leads to problems. (mum.org)
- An increase in insulin levels causes your ovaries to make and release male hormones (androgens). (clevelandclinic.org)
- On the other hand, steroid use can stimulate the production of insulin, which increases the amount of food and fluid that the muscles can absorb, anabolic steroid regimen. (madreality.tv)
Irregular1
- High androgen levels prevent your ovaries from releasing eggs, which causes irregular menstrual cycles. (clevelandclinic.org)
Graafian1
- Folliculogenesis is the process in which a recruited primordial follicle grows and develops into a specialized graafian follicle with the potential to either ovulate its egg into the oviduct at mid-cycle to be fertilized or to die by atresia. (glowm.com)
Receptor gene1
- Mutation analysis of the androgen receptor gene is now commercially available. (medscape.com)
Gene2
- In Kennedy disease (spinal and bulbar muscular atrophy [SBMA]), a motor neuron disease caused by a CAG expansion in the AR gene, androgen insensitivity appears later in life, with postpubertal gynecomastia being the most common sign. (medscape.com)
- Reduced or absent function of the receptor for follicle stimulating hormone associated with a mutation in the FSHR gene. (nih.gov)
Ovary1
Production2
- During puberty, there is an increased production of male sex hormones called androgens . (progressivehealth.com)
- These hormones change the nature of the sebaceous follicles and stimulate the increased production of sebum from the sebaceous gland. (progressivehealth.com)
Endocrine2
Atresia2
Reproductive hormones1
- This causes your reproductive hormones to become imbalanced. (clevelandclinic.org)
