Female physiology before pregnancy is the prime focus of this sqadia.com medical V learning lecture. From a discussion on female reproductive system, gonadotrophins and ovarian cycle to menstruation, role of hormones and hypogonadism all the significant terms have been comprehensively explained. Moreover, feedback effects, release of GnRH, puberty and certain contraception methods have been illustrated.
Hormones and Reproduction
In the beginning, physiological anatomy of female reproductive system along with the primary oocyte and female hormone system has been highlighted. Furthermore, ovarian cycle and gonadotrophin hormones in addition to their functions and second messenger system has been elaborated. In the end, formation of corpus luteum has been conversed about.
Initially, an overview of ovarian and menstrual cycle has been put forth. Following this, follicular phase of ovarian cycle, development of antral and vesicular follicles in conjunction with the follicular development has been thoroughly explained. Moreover, cause of atresia, ovulation, hormones and hormonal initiation of ovulation has been shed light upon.
Primarily, luteal phase of ovarian cycle is explicated followed by a discussion on granulosa cells and corbica albicans. Furthermore, luteinizing function of LH, luteinisation, corpus luteum and follicular development. Besides this, estrogen, progestin, estrogen and progesterone transportation and role of liver in estrogen degradation has been elucidated.
Role of Hormones and Menstruation
Starting off from an elaboration of effect of estrogen on fallopian tubes to a broad explanation of estrogen effects on shoulder, breast and functions of progesterone. Stages of monthly endometrial cycle, menstruation, loss of hormonal stimulation alongside desquamated tissue have been brought under consideration. Moving further, menopause and its causes, treatment, leukorrhea and abnormalities of ovarian secretion have been highlighted.
Feedback Effects and Puberty
From an elucidation on secretion of GnRH, hypothalamic center for release of GnRH and feedback effects of estrogen and progesterone, hormone inhibin and HPA axis has also been elaborated. Additionally, pre and postovulatory secretion of ovarian hormones, puberty, pill method and contraception have been discussed. Conclusively, female sterility is interpreted.
