Evaluation of the Quantitative Expression and Correlation between Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) During Follicular phase in Primary Infertile Women of Reproductive Age

Background. PCOS is one of the most common endocrinological pathologies in women of reproductive age, manifested by a wide range of clinical manifestations. There are many unresolved issues related to the pathogenesis, diagnosis and treatment of this pathological condition in different periods of reproductive age. Aim the objective of the study was to identify the features of the functioning of the pituitary-ovarian system in women with PCOS at different periods of reproductive age. Methods. Study was performed in 20172019 at the FSPSI SCFHHRP, and involved women aged 1845 years. The study groups included women (a group of women with PCOS and a control group) in the follicular phase from 1 to 12 days of the menstrual cycle. As a result of the survey, a group of 44 women with PCOS and a group of 56 healthy women were formed. PCOS was diagnosed according to ESHRE/ASRM criteria (Rotterdam, 2003). Next, subgroups of women in early reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 29) and a control group (n = 22). And groups of women in late reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 15) and a control group (n = 34). Conducted: questionnaire survey, general and gynecological examination, ultrasound examination of the pelvic organs, laboratory tests, statistical data analysis. Results. In women with polycystic ovary syndrome of early reproductive age (1835 years), we detected an increase in the level of testosterone by 2 times, DHEA-S by 1.3 times, 17-OH-progesterone by 2 times, sex steroid-binding globulin by 1.4 times, in comparison with control group. The ratio of luteinizing hormone to follicle-stimulating hormone increased by 52%. In women with polycystic ovary syndrome of late reproductive age (3545 years), we detected an increase in the level of testosterone by 1.5 times, 17-OH-progesterone by 1.9 times, luteinizing hormone by 1.4 times, sex steroid-binding globulin by 1.6 times, in comparison with control group, without any significant differences in DHEA-S. At the same time, the ratio of luteinizing hormone to follicle-stimulating hormone increased by 60%. Conclusion. The hormonal profile of women with PCOS of early and late reproductive period is characterized by series of age-related changes in the pituitary-ovarian system, which should be taken into account in preventive and therapeutic measures.

Stimulating Hormone

A normal menstrual cycle is the end result of a sequence of purposeful and coordinated events that occur from intact hypothalamic-pituitary-ovarian and uterine axes. The menstrual cycle is under hormonal control in the reproductively active female and is functionally divided into two phases: the proliferative or follicular phase and the secretory or luteal phase. This tight hormonal control is orchestrated by a series of negative and positive endocrine feedback loops that alter the frequency of the pulsatile secretion of gonadotropin-releasing hormone (GnRH), the pituitary response to GnRH, and the relative secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary gonadotrope with subsequent direct effects on the ovary to produce a series of sex steroids and peptides that aid in the generation of a single mature oocyte and the preparation of a receptive endometrium for implantation to ensue. Any derailment along this programmed pathway can lead to an abnormal menstrual cycle with subsequent impact on the ability to conceive and maintain a pregnancy.

ABSTRACTTwo groups of 19 Border Leicester cf × Scottish Blackface 9 ewes were fed so that ewes of one group were in a very high level of body condition at mating (mean score 3·35) and had a high level of intake. Ewes of the second group were in moderately high condition (mean score 2·74) and were given a live-weight maintenance ration. Ewes in the high group had a higher ovulation rate than those of the moderate group (3·36 v. 2·33) but a lower number of embryos per ewe mated (1·16 v. 1·42). Mean follicle stimulating hormone profiles were similar for ewes of the two groups during the luteal and follicular phases of the cycle before mating and during the subsequent oestrus. Mean prolactin concentrations were higher in ewes of the high group during the follicular phase and oestrus but not during the luteal phase. Mean luteinizing hormone (LH) concentrations were higher in ewes of the high group during the follicular phase and oestrus but not during the luteal phase. Mean LH concentrations were similar for the two groups at all times but the frequency of LH pulses was higher in the high group during the follicular phase.Ewes that were not pregnant at slaughter had abnormal progesterone profiles following mating, abnormal pre-ovulatory LH surges or failed to show oestrus. These abnormalities were not related to gonadotrophin profiles prior to oestrus.
