Objectives:
Lipids and hormones levels in nonpregnant and pregnant with uneventful gestation (from I, II, III trimester) were estimated and its correlation was evaluated.
Methods:
The study group consisted of 219 women: 49 nonpregnant and 170 pregnant women (35 in I trimester, 35 in II and 100 in III trimester of gestation). All subjects were healthy. Following parameters were measured in blood serum: total lipids, LDL total fraction, (beta-lipoproteids), cholesterol both total and free, HDL cholesterol, LDL cholesterol. Percentage of free cholesterol contained on total cholesterol was evaluated. HPL and estrogens levels were estimated.
Results:
Serum levels of total lipids, phosphlipids, triglicerides, total fraction of LDL and its contains of cholesterol increase with gestational age (p < 0.001). During pregnancy positive correlation between estrogens, HPL and triglycerides was also observed (p < 0.001). Additionally in II trimester positive correlation of total cholesterol, phospholipids and HPL was noted (respectively r = 0.469 p < 0.001 and r = 0.452 p < 0.01).
Conclusions:
In case of women with uneventful pregnancy positive correlation between estrogens and total lipids, total fractions LDL and triglycerides was stated. Also positive correlation among lipids parameters and HPL concentration was noted. No correlation between HPL and free cholesterol, LDL, HDL cholesterol nor between estrogens and total cholesterol, free cholesterol and LDL cholesterol was found. Lipids status in case of nonpregnant women is multihormonaly influenced.

Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...

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...

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
01:22Target 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...
01:22Hormonal 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.
