Question

match each factor with its role in infertility
role in infertility
thyroxine controls length and regularity of menstrual cycle
scars from infection(e.g., gonorrhea, pelvic inflammatory disease) block the path of the ovum
fsh, lh hormones are needed for follicle development and ovulation in women and sperm production in men
excessive estrogen may prevent ovum implantation, low progesterone makes pregnancy difficult to maintain
testosterone is necessary for the maturation of sperm cells
may increase temperature of the testis, reducing or stopping sperm production
having only one testis reduces testosterone levels and sperm count
causes scarring in uterus and tubes, making implantation impossible
factor
testes hormone imbalance
ovary hormone imbalance
varicocele
endometriosis
tubal scarring
agenesis (undescended testis)
pituitary hormone imbalance
thyroid hormone imbalance

Explanation:

Each factor is matched to its specific role in infertility based on reproductive physiology and known medical impacts of the condition/hormone imbalance.

Answer:

• Thyroid hormone imbalance → Thyroxine controls length and regularity of menstrual cycle
• Tubal scarring → Scars from infection (e.g., gonorrhea, pelvic inflammatory disease) block the path of the ovum
• Pituitary hormone imbalance → FSH, LH hormones are needed for follicle development and ovulation in women and sperm production in men
• Ovary hormone imbalance → Excessive estrogen may prevent ovum implantation, low progesterone makes pregnancy difficult to maintain
• Testes hormone imbalance → Testosterone is necessary for the maturation of sperm cells
• Varicocele → May increase temperature of the testis, reducing or stopping sperm production
• Agenesis (undescended testis) → Having only one testis reduces testosterone levels and sperm count
• Endometriosis → Causes scarring in uterus and tubes, making implantation impossible
